112 QUADRUMANA. 



the head and limbs, mouse-color on the shoulders, and a grayish-red on 

 the tail ; its total length is about fourteen inches, the tail being about 

 three inches. 



Mr. Sclater writes of two specimens in the Zoological Gardens in 

 London: "Our Pottos never voluntarily appear by daylight, but come 

 out early in the evening for their food ; they are then ver}- active and leap 

 about the perches of their cage all night long. Their food is ripe fruit 

 of all kinds, cooked rice, milk and bread sweetened, and cooked meat 

 chopped fine. They catch very cleverly little birds that are put in their 

 cage, and tear them to pieces at once ; they seem to be delighted with 

 such a change of diet." 



X.— GENUS ARCTOCEBUS. 



The Angwantibo, Arctoccbus Calabarcnsis, the only species, is a qative 

 of Old Calabar. It is remarkable for the total absence of the forefinger, 

 for the possession of a long claw on the first toe, and for an almost rudi- 

 mentary tail. A thick and long woolly fur — somewhat shorter on the 

 face and the backs of the paws — covers the body. It is of a brownish- 

 gray on the back, but on the lower surface of the body and on the inner 

 side of the limbs it is dark-brown. 



Althougii the Angwantibo has been known since the year 1680, little 

 has been ascertained respecting its habits. 



XI.-GENUS GALAGO. 



This solitary genus of the sub-family Galagin.e comprehends fourteen 

 species, all ft)und in Africa from Senegal to Zanzibar and Natal. While 

 the Lemuridx' hitherto described are remarkable for the development 

 of the power of sight, the Galagos are distinguished by the acuteness of 

 their hearing. The body is slender, but looks stouter from its possession 

 of a thick fur; the comparativclv large head is remarkable for the largely 

 developed naked ears, and by tlie close-placed large e3-es. The limbs 

 are of moderate length, the forefinger, the second toe, and in some 

 species the middle finger and toe as well, are furnished with claw-like 

 nails. The tarsus is elongated, the tail bushy. The dental formula is
