ZOOLOGY. 
Tue Crustacea or Laxe Titicaca. — In the Naturalist (x. 
380) we have called attention to the exploration of Lake Titicaca, by 
Messrs. Agassiz and Garman, and alluded to the marine nature of the 
crustacean fauna of this lake. Since then Mr. W. Faxon has published, in 
the Bulletin of the Museum of Comparative Zodlogy, descriptions and 
figures of the crustacea of the lake. “ Excepting,” he remarks, “a spe- 
cies of Cypris, all the specimens collected belong to one amphipodous 
genus, Allorchestes, which had hitherto afforded but one or two authentic 
fresh-water species, ranging from Maine to Oregon and the Straits of 
Magellan. Seven new species are described in this paper from Lake 
Titicaca. Several of them are remarkable among the Orchestide for 
their abnormally developed epimeral and tergal spines. Some are also 
noteworthy as comparatively deep-water forms of a family commonly 
regarded as preéminently littoral. I believe that no Orchestide have 
heretofore been found at a depth so great as sixty-six fathoms,’ unless 
it be Orchestia (Talitrus) Brasiliensis Dana, and Nicea media Dana 
1 The greatest depth of the lake is 154 fathoms.
