upon the same scale (viz. l-24tli to l-1800th inch), it must not 
be assimied that the trapezoids are as regularly formed through- 
out the mass ; hence they must, to a certain extent, be viewed 
more or less as diagrammatic.

X. — List of the Species of Crustacea collected hy tJie Rev. A. 
E. Eaton at Spitzhergen in the Summer of 1873, with their 
Localities and Notes. By Edward J. Miers, F.L.S., 
F.Z.S., Assistant in the Zoological Department, British 
Museum. 
A SMALL collection of Crustacea, made by the Kev. A. E. 
Eaton during a voyage with B. Leigh Smith, Esq., to Spitz- 
hergen, in 1873, was presented to the Trustees of the British 
Museum in the following year. The species are most of them 
well-known Arctic forms ; but the specimens generally are of 
a large size and in an excellent state of preservation. The 
value of the collection is further enhanced by the exact loca- 
lity of nearly every specimen being recorded. 
The crustacean fauna of the Scandinavian and adjacent 
arctic seas appears to have been investigated more thoroughly 
than that of any other great region of the globe, if we may 
judge from the amount of literature relating to it ; for in the 
Introduction to his ' Skandinaviske og Arktiske Amphipoder ' 
(Christiania, 4to, 1872), A. Boeck enumerates no less than 273 
publications in which animals of this order alone are referred 
to in connexion with this area. 
In 1863 A. V. Goes published a list of the Decapoda inha- 
biting the region mentioned, with remarks on the geographical

distribution of each of the species (in (Efvers. Kongl. Vetensk. 
Akad. Forhandl. p. 161) ; in addition to all which are men- 
tioned below, be records many others from Spitzbergen. 
The long-known and widely distributed Isopod JEga psora. 
Pennant {2Ega emarginata^ Leach), has not, to my knowledge, 
been obtained in these seas before. 
In 1865 the Spitzbergen Amphipoda were dealt with by 
A. V. Goes (in (Efvers. af K. Vet. Akad. Forh. 1865, pp. 517- 
536, pis. 6). Anonyx bidenticulatus, S. Bate, is the only one 
in the present collection that is unnoticed by him. Mr. 
Spence Bate, in the Catalogue of Amphipodous Crustacea in 
the collection of the British Museum (1862), referred to this 
species as synonymous with A. nugax^ Phipps ; but a careful 
comparison of the two forms leads me to diifer from him in 
opinion, and to consider them to be quite distinct from one 
another *. 
The cirriped Balanus porcatus, Da Costa, is another addi- 
tion to our knowledge of the Spitzbergen fauna ; and so is one 
of the two species of Pycnogonida collected, Nymphon gracile.

which were sent to the Rev. A. M. Norman for examination. Fragments 
of Vertumnus serratus. Fab., and of Byblis Gaimardi, Kroyer, were

Hah. Green Harbour ; Lomme Bay, in 15 fathoms. 
A large series of specimens of various ages is in the collection. 
There is a median longitudinal series of four spines on the carapace, 
of which the second and third are placed near to one another and 
are sometimes united. In the adult specimens the lateral ridges 
are less strongly defined, and the spines upon the carapace and first 
and second abdominal segments are more obtuse or even obsolete. 
The largest specimen (a female with ova) has a length, from tip of 
rostrum to extremity of telson, of nearly 4 inches.

Hah. Carl Island and Cape Torell, in 12-18 fathoms. 
In nearly all the specimens that I refer to this species the three 
or four teeth on the inferior margin of the rostrum are very ob- 
scurely defined. In one specimen they are entirely obsolete. The 
upper margin of the rostrum in this species is always smooth, entire, 
and unarmed.

ffab. Near Carl Island and Cape Torell, in 12-18 fathoms. 
In the single specimen of this species in the collection the ros- 
trum is oLtusely pointed and reaches beyond the peduncle of the 
short superior antennae, 'fhe coxae of the second pair of pereiopoda 
have the anterior margin straight, and are produced posteriorly to a 
distance equalling twice the width of the coxa at its upper margin. 
The bases of the fifth pair of pereiopoda have the postero-lateral 
margins rounded. The third segment of the pleon has the posterior 
margin regularly concave excavate. The colour is dark olive-green, 
with a small faintly marked white spot on each side of every seg- 
ment of the body.

Hah. Carl Island and Cape Torell, in 12-18 fathoms. 
Several specimens are in the collection. They all have the ros- 
trum acute and shorter than the peduncle of the superior antennae. 
Coxae of the second pair of pereiopoda hatchet-shaped ; the anterior 
margin slightly concave, the postero-lateral lobe acute and produced 
to a distance not exceeding the width of the coxa at its upper 
margin. Bases of fifth pair of pereiopoda with the postero-lateral 
angle acute. Third segment of the pleon with the posterior margin 
angularly excavate. Colour yellowish white, with transverse series 
of brown patches on each segment and coxae.

The specimens which I refer to this species are distinguished by

Boeck, in his ' Skandinaviske og Arktiske Amphipoder,' refers Mr. 
Spence Bate's figure of Z-. nugax to Socarnes VoJdii, Kroyer — wrongly, 
I think ; for in that species the inferior angle of the third segment 
of the pleon is " valde rotundatus " (see also Kroyer's figure of S. 
Vahlii in the ' Voy. en Scandinavie,' pi. xiv. fig. 1).

Acunthozone hystrix, Boeck, Forhandl. Vidensk. Selsk. p. 184 (1870). 
Hah. Carl Island and Cape Torell, in 12-18 fathoms. 
This species has been referred by Boeck to the Oniscus cuspidattis 
of Lepechin (Acta Acad. Sci. Petrop. p. 249, pi. viii. fig. 3, 1780) ; 
but the species figured by that author diifers in having vertically 
projecting spines upon only the first four segments of the pereion. 
The species figured by Buchholz (Zweite deutsche Nordpolarf. 
Zool. Crust, p. 362, pi. xi.) as Acanthozone hystrix diff'ers from that 
figured by Owen in the more numerous and closely placed spines 
upon the posterior margins of the basa of the pereiopoda, and in 
the form of the rostrum, and is, I think, distinct. 
The name Acanthozone has been substituted by Boeck for Acan- 
thosoma, the latter name being preoccupied in entomology.

Polyzoa. Colour in life reddish brown. 
Now and then a moving speck might be seen on the smooth sur- 
face of the water from the boat. Sometimes close inspection would 
enable the cause of the minute disturbance of the sea to be detected 
in the form of a Caprella making strenuous efforts to swim, throwing 
itself about like a letter S in agonies.

Hah. Carl Island and Cape Torell, in 12-15 fathoms. 
The colour of the animal is light brown, with very short cinereous 
hairs, which render it scabrous to the touch ; the legs are banded 
with very fine longitudinal lines of a deeper brown. The joints of 
the tarsi are subequal ; the second joint of the palpi is rather longer 
than the third. This species is evidently very nearly allied to N. 
grossipes, Fabr., as described by Kroyer (Nat. Tidsskr. n. R. i. p. 108, 
1844) and figured (Voy. en Scand. pi. xxxvi, fig. 1) ; but in that 
species the third joint of the palpi is much longer than the second, 
and the animal is described as glabrous. 
Leach's specimens of N. gracile in the collection of the British 
Museum are much smaller and slenderer than the specimens from 
Spitsbergen; but the proportional length of the joints is the same, 
and it is evident that the animal becomes more robust as it increases 
in age.
