PTEROPODA. 
A rather large number of Pteropods and some other pelagic 
shells (51 species) caught in the tow-net in the Pacific and At- 
lantic are enumerated, with exact statements of the longitudes 
and latitudes, and with some additional remarks, by Commander 
Hugh II. Knocker. Several species are stated to occur in both 
oceans, in their southern parts as well as northern, viz. Hyalcea 
lo7igirostris (Lesueur), quadridentata (Lesueur), Creseis clava 
(Rang), (Rang), Spirialis bulimoides (Orb.), and others. 
The hours between sunset and sunrise, especially on moonlight 
nights, are the most favourable for this object. The Atlanta 
are the first to come to the surface, then the species of Creseis, 
and finally the Hyalace and Cleodora, which appear usually an 
hour after sunset. Proc. Zool. Soc. 1868, pp. 615-622. 
Hyalcea, Cleodora, Creseis, Cuviera, and Spinalis. A great number of 
localities for several species of these genera are given by 11. Knodver j he 
tliinks Cl. pyramidata (Peron) and lanccolata (Rang) to be distinct, having 
found both equally large, and describes some other species without giving 
them new names. L. c. 
Clio borealis (Pall.) and other pteropods are stated to occur chiefly in 
those portions of the Arctic sea which abound in Diatomacete, and owe to 
these a dark hue. Brown, Journ. of Botany, March 1868; and Quarterly 
.loiirnal of Microscopical Science, viii. 1868, p. 244.
