can, therefore, be little doubt that the true description of 
Cocytus will be as follows :— 
Adolias Cocytus, Fabricius. 
¢d. Alis integerrimis falcatis, supra nigro-fuscis, lineolis discoideis 
nigris, margine externo viridi-ceruleo extts violascente, posti- 
cis lato: subtus omnibus ochreis; anticis lineolis quinque discoi- 
deis, striga sexlunulata submarginali, nebula marginali vio- 
lacea; posticis lineolis basalibus vix distinguendis, striga sub- 
marginali lunulata fusca. 
Exp. alar. unc. 2,!,-2,9.. 
The Indian species will of course have to be described ; and 
I therefore propose for it the name of A. lepidea. 
Adolias lepidea, sp. nov.

Figures of Characteristic British Fossils ; with Descriptive Remarks.

Tris first instalment of a work of good promise, well planned and 
well begun, is very acceptable to geologists, both amateur and pro- 
fessional. The heavy task that lies before the geological inquirer 
who wishes to set eyes on any large group of fossils peculiar to a 
system of strata often checks his progress, and is always a trouble. 
He may have recourse to Bronn’s comprehensive ‘ Lethewa geognos- 
tica,’ but it is cumbrous, expensive, and German; nor does it place 
before him the fossils of the several ‘‘ formations” of each geological 
“system,” as is proposed to be done in the work before us. The 
still more voluminous ‘ Paléontologie francaise’ is further beyond 
_ his requirements, being arranged to give every known species in de-
