Subgenus Plectiscus, Gr< 
There is so much dissimilarity among the species included 
in this group that I would propose dividing it into two, and 
adding a third for the reception of some small species, which 
I formerly arranged with Xorides, but which agree with the 
genuine Plectisci except in respect of the wings.

Subgenus Acrodactyla (Barypus*, C. 490 b .) 
Abdomen basi attenuatum, segmentis intermediis obsoletissime im- 
pressis;/. ventre apice fisso, terebra exerta brevi. Areola nulla. 
Tarsi apice incrassati, unguibus lobo infero dilatato obtuso. 
The species of this little group are closely allied to the subg. 
Polysphincta (and to P. percontatoria in particular), but may 
be distinguished by the smoother abdomen attenuate at the 
base, the narrower stigma, and the structure of the claws. 
From certain Pimples of the typical subgenus which agree in 
this last respect, they may be known by the want of the areolet, 
in addition to the former characters.

This species differs from all the former in many respects. 
The spiracles are placed at the middle of the first abdominal 
segment : — the anterior face of the tibiae is beset with minute 
spines : — the proportions of the labial palpi are different, the 
intermediate joints being very short and the last very long. 
The antennae of the male are not crenulate in the middle. 
The areolet is either totally wanting, or if faintly indicated, it 
is triangular. Notwithstanding these and other differences I 
have left it in this group for the present, as it differs yet more 
widely from Ichneumon ; neither do I think it can with any 
propriety be referred to Mesoleptus, and I know no other 
group with which it is likely to be associated. 
Genus Lampronota. 
Abdomen subsessile laeve convexum, /. ; ventre apice fisso, valvula 
ventrali obtusa, terebra exerta longa. Thorax gibbulo-cylindricus, 
mesothoracis scuto bisulco, metathoracis spiraculis transversis. Ca- 
put oblatum, clypeo transversim impresso. Antennae longse graciles, 
articulo 3° praelongo, 5° et 6° in mare denticulatis. Pedes postici 
elongati validi. Areola nulla. 
I have adopted the group as restricted by Mr. Stephens in 
his synopsis of the genera. It has some resemblance to 
Echthrus, but is perhaps more nearly allied to Acoenites ; I 
have not a specimen of the latter genus to make the compa- 
rison.

XVI. — Communication respecting Fossil and Recent Infusoria 
made to the British Association at Newcastle. By Prof. 
Ehrenberg. 
To the Editors of the Annals of Natural History. 
Gentlemen, 
You w T ill much oblige me by inserting the subjoined notice, 
which has been occasioned by the erroneous report in the 
Athenaeum of the statements made by me at the late Meeting 
of the British Association in Newcastle, in the section of bo- 
tany and zoology, w r hich statements, so far as I can recollect, 
were to the following import : — 
For the purpose of physiological inquiries I have occupied 
myself with the investigation of microscopic organized beings, 
not only in Europe, but also upon several voyages for several 
years in other quarters of the globe. The results of my observa- 
tions had been hitherto scattered in single memoirs, published 
in the Acts of the Royal Academy of Berlin. Within these few 
weeks, however, my large work on this subject has been com-
