Mictomys-— Continued. 
Mictomys: uikrós, mixed; 4/2c, mouse—from the animal’s resemblance to Syn- 
aptomys in general appearance, skull, and teeth; and to Lemmus in having the 
thumb armed with a truncated, strap-shaped nail.

Midas: Midas, in Grecian mythology a king of Phrygia, who was endowed with 
the power of turning everything he touched into gold. The name was first 
used in mammalogy as a specific designation for Simia midas, evidently on 
account of the golden-yellow or bright-reddish color of the animal’s hands 
and feet, and was afterwards adopted for the genus.

“Tn the Journal de Physique, Dr. Leach has pointed out the generic differences 
that exist between the Black and the Red Orang-otans. The first genus, 
Mimetes, Leach ( Chimpanse), the nearest animal to man, has no intermaxillary 
bone; it has the last joint of the great toe perfect; and has the ligamentum 
suspensorium of the thigh bone. The type is Simia troglodytes" from West 
Africa (Ann. Philos. 104). "This is an error, as the generic name given to the 
‘Chimpanzé’ in the Journal de Physique (LXXXIX, 156, Aug., 1819) is 
Troglodytes, not Mimetes. 
“This genus was proposed by W. E. Leach about 1816,* and antedates both 
Troglodytes of Geoffroy and Anthropopithecus of De Blainville." (Covers. )
