Compare on these two species my remarks in Tijdschr. voor nat. Gesch. 

 Till. 1841, bl. 337 348, with figures.

c) Tail none (Loris GEOFFR. Body slender ; eyes very large, almost 

 contiguous. Nose acute, sub-ascending). 



Sp. Stenops gracilis, Loris gradlis GEOFFR., Lemur tardigradus L. (Mus. Ad. 

 Frid. 1754, Lemur <f cauda omnino nulla" p. 4), BUFF. xni. PI. 30, 

 ADDEB. Loris, PL 2 ; in the island of Ceylon, smaller than the preceding 

 species. On the vascular plexuses of the limbs in this genus see above, 

 p. 586. Under the tongue in this genus and the following is situated an 

 aponeurotic lamina, which is divided at its anterior, thinner end, into 

 filaments or slips. This arrangement (a development of the frenum of 

 the tongue) has been described, incorrectly in my judgment, as though the 

 tongue were double, or even as if a bird's tongue were present under the 

 mammalian tongue. 



Lemur L. (excl. of Lemur tardigradus and Lemur volans). 

 Teeth as in the preceding genus. Snout produced. Eyes lateral. 

 Ears short. Index of hand longer than thumb. Tail very long, 

 hairy throughout.

 Mus. II. pp. 15 seq. (with an excellent figure), Diet. univ. d'Hist. nat., 

 Mammif. PI. 6 B, fig. 2 ; grey, ruddy on the back, white below ; the tail 

 ringed white and black. Lemur Macaco L., Lemur niger GEOFFR., 

 EDWARDS'S Gleanings, Tab. 217 (fig. copied in SCHREB. Tab. 40 A), 

 variegated : Lemur Macaco auctor., BUFF. xni. PI. 27, AUDEB. Makis, 

 PI. 5, 6; Lemur Mongoz L., BUFF. xni. PI. 27, (cop. in SCHREB. 39 A); 

 To these species, known to LINNJEUS, various others have been since 

 added : Lemur albifrons GEOFFR., AUDEB. Makis, PI. 3, GUER. Traite elem. 

 tfHist. nat., Zool. PI. 2, fig. 3, &c. All the species are from the island 

 of Madagascar. 



Chirogaleus GEOFFR. (A scarcely distinct genus, with head 

 shorter, the inter/orbital space and ridge of nose convex.) 



Sp. Lemur griseus GEOFFR., BUFF. Suppl. viz. PI. 34, AUDEB. Makis, PI. 7 ; 

 Chirog. Milii GEOFFR., Myspithecus typus Cuv. Mammif. ed. 4to, 

 PI. 83. The figures of COMMERSON (Ann. du Mus. xix. PI. 10), on which 

 GEOFFR. (ibid. pp. 171 175) originally founded this genus, cannot be 

 referred to these species, which were discovered later. 



B. With tarsus elongate. 



Otolicnus ILLIG., Galago GEOFFR. (Teeth 36, as in Lemur). 

 Eyes large. Ears large, naked. Tail long (mostly longer than 

 body), villous.
