ON THE LEMURID&. 195 



to the former. Both species are figured in Buffon, the first under the title 

 Loris (Hist. Nat. xii.), the second under that of Loris de Bengale (Hist. NaV 

 Supp. vii.). 



It will be seen that with the genus Microcebus we leave Madagascar, and, 

 with a modification of the Lemurine form, enter upon other portions of the 

 globe ; namely, Africa and India, with the Indian Islands. The genus Loris is 

 exclusively Indian ; there has, however, been associated with it, or rather with 

 Nycticebus, by Geoffroy, an animal from Sierra Leone, termed Potto by Bosman 

 (Lemur Potto, Linn., Galago Gruneensis, Desm.), of which, until very recently, 

 the characters were but imperfectly understood. The acquisition of a specimen 

 in spirits, by the Zoological Society, enabled the late Mr. Bennett to characterize 

 it afresh as the type of a distinct genus, to which he gave the name of Pero- 

 dicticus; and from his paper in the Proceed, of the Zool. Soc. for 1831 (p. 109) 

 we shall make a few extracts, premising that our own examination of the spe- 

 cimen in question leads us to coincide with the views of that naturalist.

Geoffroy's Perodicticus (Perodicticus Geoffroyi, Benn.). — General colour 

 chesnut brown, slightly tinged with grey, becoming paler beneath ; the fur soft 

 and woolly, interspersed with a few cinereous hairs. Length of head and body 

 eight inches and two-tenths ; of the tail, including the hair, two inches and three- 

 tenths, without the hair one inch and six-tenths. " The head is. rounded, with 

 a projecting muzzle ; the nostrils are lateral, small, sinuous, with an intermediate 

 groove extending to the upper lip ; the tongue is rough, with minute papillae, 

 rather large, thin, rounded at the tip, and furnished with a tongue-like upper 

 layer, which is shorter than the tongue itself, and terminates in about six rather 

 long, lanceolate processes, forming a pectinated tip. The eyes are small, round, 

 somewhat lateral, and oblique ; the ears moderate, open, slightly hairy, both 

 within and without. The body is rather slender. The limbs are nearly equal, 

 long, and slender ; the fingers moderately long. On the fore-hands the index is 

 excessively short, the first phalanx being concealed, and the ungueal phalanx 

 (the only phalanx free) being barely large enough to support a rounded nail."
