1144 Recent Literature, [ November, 
and of Gammarus limneus and Hyalella dentata are given, the stu- 
dent’s attention being drawn to those points not requiring dissec- 
tion. The figures might have been better drawn and engraved, 
so that the dent should have a better model of such work be- 
fore him, but the brochure will be useful, and we are glad to see 
such a publication adapted for the use of American students. 
Mogsius AND HEINCKE’s FISHES OF THE GERMAN OCEAN— 
This appears to be an excellent brief account of the marine 
of the German ocean prepared for popular use, and issued by the 
Commission for the scientific investigation of the German ocean, 
whose headquarters are at Kiel. Every species pee is ac- 
companied by a good outline figure. There is a map 
their geographical distribution. It is published by Paul pe 
Berlin, 1833, and contains 206 pages.
