(ii.) Some of ray arguments depend, as Prof. Blake points 
out, on the homology of the lamellae in the pad of Sepia with 
the septa in the Belemnite-phragmocone. This homology is 
doubted by Prof. Blake, who now suggests that the lamellce 
of the pad are homologous with the calcified membranes of 
the nacreous layer in the shell-wall of Nautilus. His argu- 
ments are three. He claims first that his observations on 
shell-structure do not countenance my view : my readers will 
decide whether Prof. Blake's description is valid evidence one 
way or the other. He states secondly that the lamella of 
Sepia " have no siphuncle, and they are not even perforated : " 
now each later-formed lamella is like an elliptical figure with the 
posterior part cut away by another broader ellipse ; the earlier 
lamellaB are of more circular outline, but are similarly incised ; 
if this incision represents the siphuncular space, then from this 
form to the form of the septa in Belosepia is a mere step ; even 
in the Belemnite the siphuncle is so external as hardly to be 
surrounded by the septum. Lastly, he states that there is no 
trace of a " cap " or of a protoconch in Sepia : the explana- 
tion of this was given by Prof. Lankester in his " Observa- 
tions on the Development of Cephalopoda" (Q. J. M. S. xv. 
p. 37) in 1875, and to the arguments of that authority no 
opposition has hitherto been offered. 
The view taken by me as to the homologies of the Sepion 
was first put forward by Voltz (Mem. Soc. Hist. Nat. de 
Strassbourg, i. p. 1) in 1830 ; I am not aware that his argu- 
ments have ever been refuted ; the view is adopted by Prof. 
Gegenbaur in his well-known text-book ; it has been con- 
firmed by recent observations, and, though I arrived at it 
independently from a study of the facts, I had no wish to 
retell an old tale. 
I accept with gratitude the support and welcome of Prof. 
Blake, and only regret that his article should necessitate a reply 
so full of controversy. For this 1 apologize to the readers of 
the ' Annals,' but would remind them of the Rabbinical 
proverb, " By the contention of students science is advanced." 
LIX. — Descriptions of two new Species of Indian Soricidse. 
By G. E. Dobson, M.A., F.R.S. 
As Mr. W. T. Blanford is about to print his work on the 
mammals of British India, and is anxious to include every 
known species from that region, he has requested me 
428 Mr. G. E. Dobson on two new Indian Soricidge. 
to publish diagnoses of the following species, of which full 
descriptions are to be found in the manuscript of the still 
unpublished part iii. of my ' Monograph of the Insectivora.' 
The following two species of Crocidura belong to the so- 
called subgenus PacJiyura^ having the dental formula 
""•^'trd.a"- '-' = 30 teeth. 
Crocidura leucogenys^ sp. n. 
Somewhat larger than C. aranea. The ears are short and 
clothed with a few short whitish hairs only ; the tail is thick 
and fusiform, and clothed as in C. murina^ numerous long, 
fine grey hairs arising out of the shorter fur ; the feet com- 
pared with the size of the body are small and slender, thinly 
clothed with short greyish-brown hairs ; a very large lateral 
gland, like that in G. onurina, is found in the usual position. 
The fur is short throughout ; above light cinnamon-brown, 
with a reddish tinge intermixed with grey, the basal half of 
the hairs bluish ; the sides of the head between the angles of 
the mouth and the ears, the chin, and part of the chest are 
dirty white, the remainder of the ventral surface greyish ; the 
up})er surface and sides of the tail are brown, the lower sur- 
face grey. 
The skull and teeth closely resemble those of C. murina on 
a much reduced scale ; they also resemble those of C. Stolicz- 
'kana., Anderson ; but skulls of quite immature specimens of 
the latter species, although much smaller, have longer upper 
tooth-rows. 
Length (of an adult male preserved in alcohol) : head and 
body 75 millim., tail 47, ear 8, elbow to end of middle digit 
(without claw) 17, manus 7, pes 12 ; skull, occipital crest to 
front edge of premaxillary bone 19, greatest width of skull 
9, length of upper tooth-row 7, length of lower tooth-row 8, 
length of mandible from condyle to tip of anterior tooth 12^. 
Hob. India {Ajmir). 
Type an adult male collected by Sir O. B. St. John. 
Crocidura Dayi, sp. n. 
Smaller than C. ruhicunda^ but with a longer tail and 
nearly as large a foot. Fur and integument dark brown 
throughout, the ventral surface slightly paler, the basal three 
fourths of the fur on both surfaces dark bluish grey Tail 
long and clothed with very short hairs ; in the single speci- 
On the Fishes of the Yangtsze-Kiang. 429 
men there are scarcely any long fine hairs to be seen ; feet 
slender and similarly thinly clothed. No trace of a lateral 
gland. 
The skull differs conspicuously from that of C. ruhicunda 
in its smaller size. The teeth differ in the shape of the first 
upper incisor as well as in the large size of the penultimate 
premolar. The first upper incisor has a large basal process 
provided with an internal basal cusp, the anterior principal 
cusp of this tooth is short and does not equal that of the 
second incisor in vertical extent ; the third incisor is smaller 
and shorter than the anterior maxillary tooth ; the small 
penultimate premolar is much larger than usual in the genus, 
being about three fourths the size of the third incisor in cross 
section at the base, and its cusp slightly exceeds in vertical 
extent the anterior basal cusp of the last premolar ; the ante- 
rior mandibular tooth has two notches. 
Length (of a skin) : head and body 74 millim., tail 60, 
pes 15^ ; skull, occipital crest to front edge of premaxillaiy 
bone 17^, greatest width of skull 9, length of upper tooth- 
row 9, length of lower tooth-row 8^, length of mandible from 
condyle to tip of anterior tooth 12. 
Hob. Madras Presidency, India (exact locality unknown). 
Collected and presented to the British Museum (Natural 
History) by Dep. Surgeon- General F. Day, CLE. 
LX. — Contrihution to our Knowledge of the Fishes of the 
Yangtsze-Kiang. By Dr. A. GiJNTHER, Keeper of the 
Zoological Department, British Museum. 
Since I had the pleasure of reporting on a collection of 
Reptiles* made by Mr. A. E. Pratt at Kiu-Kiang, on theYang- 
tsze River, he has proceeded further inland, to Ichang, a distance 
of 1000 miles from the mouth of the river. He was fortunate 
enough to obtain there a specimen of the porpoise, the exist- 
ence of which had been mentioned by several travellers 
(Blakiston, A. J. Little), and of which I especially desired 
* See mite, p. 165. I regret not to be able to make use of the notes on 
Chinese lishes in ' La Pisciculture et la Peclie en Cliiue par P. Dabry de 
Thiersant,' as the figures as well as the accompanying notes are the work 
of persons not conversant with the rudiments of descriptive ichthyology, 
and as likelv to lead to misconceptions as to assist in the deterniiuation 
of the species.
