576 THE AMERICAN NATURALIST.  [Vou. XXXIV. 
eral references! which relate pointedly to the large, bear-like, 
bushy-tailed ant-eater, popularly known as the great ant-bear 
or great ant-eater. The habitat given is Brasilta, Cap. b. spei. 
The description of M. ¢ridacty/a in this edition is enlarged, and 
brings in more points belonging to M. jubata, but it retains all 
its old references but one, and includes two more — Brisson's 
Quad., p. 27, and Bout. /ava, p. 320, the latter of which I cannot 
examine. Brisson’s description shows us the same beast of 
mixed character as above. The habitat, according to Linnzus, 
is now ndia orientali. 
As M. jubata is generically distinct from M. tetradactyla, and 
no old name being available, I propose the name “ Falcifer." ? 
The species of Myrmecophagidz, therefore, would stand as 
follows : 
Cyclopes Gray, 1821. 
C. didactylus (Linnaeus). 
Myrmecophaga Linnzus, 1758. 
M. tetradactyla Linnaeus. 
M. tetradactyla straminea (Cope). 
M. longicaudata Wagner. 
M. sellata Cope. 
Falcifer, Rehn, 1900. 
F. jubata (Linnaeus). 
II. DipErPuis. 
Under this generic name in the tenth edition are described 
five species, z.e., Marsupialis, Philander, Opossum, Murina, and 
Dorsigera. Of these, three have been since separated generi- 
cally; Philander becoming Philander philander (1808), Opossum 
becoming Metachirus opossum (1854), and Murina becoming 
Marmosa murina (1821). The species Dorsigera is a synonym 
of Murina, and Marsupialis is unrecognizable (see Alston, Biol. 
Centr. Amer., p. 196, footnote, and Allen, Bull. Amer. Mus. Nat. 
Hist, Vol. EX, p. 43). 
1 Two of these references are inaccessible to the writer. 
2 From falx + fero, ‘sickle-bearing,’ referring to the sickle-shaped claws of the 
fore feet.
