792 The American Naturalist. [September, 
fishes enumerated are chiefly those of the Atlantic streams. They are 
included in the following orders: Nematognathi, 23 sp.; Plectospon- 
dyli, 14 sp.; Holostomi, 1 sp.; Percomorphi, 8. A new Gobius is 
described. The Mammalia number 92 species, of which 11 are Marsu- 
pialia, 5 Edentata, 23 Glires, 16 Chiroptera, 20 Carnivora, 17 Diplar- 
thra, 3 Quadrumana, and 2 Cetacea. An interesting feature is the 
number of species of Didelphyidae, of which a new species is described. 
The author includes without hesitation the Felis braccata Cope in the 
F.jaguarondi, probably because in the original description it is said to 
be allied to that species. As matter of fact, however, it is very little 
allied to that species, and has no close relationships to any other. It is 
remarkable for the large size and pointed outline of its ears, which are 
sharply bicolor on the upper surface. The mounted skin shows faint 
oblique bands on the sides. Its very obscure colors render it easy of 
concealment, which, perhaps, with its apparent rarity, accounts for its 
having so long escaped the observation of naturalists. Von Ihring also 
asserts the identity of the Sphingurus sericeus with the S. villosus. If 
the latter is, as generally asserted, identical with the S. insidiosus, the 
S. sericeus is distinct enough.—E. D. Corr.
