an account of his observations on the structure of the chorion and 
micropyle in the eggs of insects. Professor A. S. Packard, 
Providence, R. I., desires alcoholic specimens of Poduridæ and 
other Thysanura with a view to a future monograph of this order. 
He will gladly name any specimens sent him for identification. 
Dr. Heylaerts publishes in the Compte-rendu de la Société 
entomologique de Belgique (p. ccvi1), remarks on the Psychides 
of the United States. He believes that other genera of these 
sack-bearing caterpillars will be discovered, such as the Epich- 
nopteryx, Bijugis and Fumea, though he adds that not an Eu- 
ropean species has yet been discovered here. He describes 
from Professor Riley’s collection Chala rileyi, and notices a 
series of seven cases of unknown species, all, except one from 
Brazil, being from the Southern and Western States and Territo- 
ries. An Asiatic species of Corydalus (C. asiatica) resembling 
in size and appearance our C. cornutus, is described and figured 
by J. Wood-Mason in the Proceedings of the Zoological Society 
of London (1884, p. 110). It occurred at the Naga hills, N. E. 
frontier of India. All the previously described species of this 
genus are American.

Tue Deep SEA EXPLORATIONS OF THE “ TALISMAN.”—The offi- 
cial report by M. A. Milne-Edwards, of the last expedition of the 
Talisman, has been published and translated by the /ndependent. 
The expedition of 1883 was divided into several distinct steps, 
the aim being to examine: 1. The coast of Africa as far as Sene- 
gal, then the shores of the islands of Cape Verde, of the Cana- 
ries and Azores, and, finally, to examine the Sargasso sea and 
study its surface fauna as well as the nature of its depths. 
In one of the first trials on the coast of Spain, the Talisman 
party found an accumulation of dead shells, having the aspect of 
the pliocene fossils of Sicily, and among which M. Fischer rec- 
ognized Cypridina islandica and Mya truncata, which are common 
in boreal seas and do not live south of England. They were as- 
sociated with some Mediterranean or pliocene shells. Off the 
coast of Morocco and the Sahara were found, at the depth of 500 
o 600 meters, numerous fishes (Macrurus, Melanocephalus, Hop- 
lostethus and Pleuronectes), crustaceans such as certain unde- 
scribed shrimps with an enormous rostrum, pointed like a sword, 
which was named Pandales ; other shrimps of the genera Penzus, 
Pasiphaea, some small crabs (Etalia, Portunus and Oxyrhynchus), 
some red Holothurians, examples of the soft-shelled sea-urchin 
(Calveria), which formerly lived in the chalk formation ; also many 
large-sized sponges, some in the shape of an enormous chapeau 
(Askonema), the others lamellated (Farrea), the others more or 
less globular. : 
Deeper down, toward 1000 and 1500 meters, fishes abounded ;
