into nearly equal coste. The pygidium and ventral surface 
are rather thickly clothed with stiff brown hairs, and extremely 
minute hairs may be detected also upon the upper surface, but 
these are not at all evident. 
This insect brings the number of described species of the 
genus Myoderma to eight, of which seven have been discovered 
since the publication of the Munich Catalogue.

Zoological Gleanings from the Royal Indian Marine Survey Ship 
‘ Investigator. By A.W. Axcocx. Simla, 1901. 4to. (Reprint 
from the Scientific Memoirs by Medical Officers of the Army, 
India. Part XII., pp. 35-76.) 
Many of the biological observations made through the medium of 
the ‘Investigator’ are buried in reports not readily accessible, and 
many are scattered among systematic papers where they are easily 
overlooked. Major Alcock therefore has thought it advisable to collect 
and classify them in a summary, together with other hitherto un- 
published facts selected from his Journal. 
Biological students are much indebted to Major Alcock for thus 
having brought this miscellaneous information within their reach, 
and we think it but right to assist him in this service to science by 
placing before the readers of the ‘Annals’ a list of the eontents of 
this collection of observations :— 
I. Illustrations of Commensalism among: 1. Sponges; 2. Zoo- 
phytes; 3. Echinoderms; 4. Crustaceans; 5. Mollusca; 
6. Fishes. 
II. Notes on Sexual Characters, Pairing, and Viviparity 
among Marine Animals :— 
. Pairing and Parental Care among HKchinoderms. 
. On Secondary Sexual Characters and Pairing among 
Crustaceans. 
. On certain Primary Sexual Characters in certain Bony 
Fishes. 
. On certain Secondary Sexual Characters in certain Bony 
Fishes. 
. On Pairing among Eels. 
. On Viviparous Bony Fishes. 
. On Viviparous Elasmobranch Fishes. 
III. On the Sounds made by certain Marine Animals: 1, by 
Crustaceans; 2, by Fishes. 
IV. Miscellaneous Notes on Stalk-eyed Crustaceans :— 
1, The early Larval Stages of Hippa asiatica, Thenus orien- 
talis, and Nephrops andamanica. 
2. On some curious Habits of Land Hermit-crabs.
