3. Cheirogaleus smithii, Gray, Ann. & Mag. N. H. 1842; 

 Cat. Mam. B. M. 16. B.M. 



Microcebus pusilluSf^&terhouse, Cat. Mus. Z. S. ed. 2. p. 1 2. no. 89. 



Le Bat de Madagascar, Buffon, Supp. iii. t. 20. 



Pale bay ; chin and beneath pale yellow ; outside of ears pale 

 brown ; orbits blackish ; streak on nose and between the orbits white ; 

 the hairs are slate-colour at the base. 



Hab. Madagascar. 



Length of hind foot 1" 2'". 



This specimen is about one-fourth the size of the C typicus. It 

 may be the young of it ; but the teeth, so far as one can see in a 

 stuffed specimen, appear to be perfect. 



Le Rat de Madagascar (Buffon, Supp. iii. t. 20) well represents 

 this animal ; but it has been considered as the type of the genus 

 Microcebus, which is described as having a long slender hind foot. 



We have a specimen in spirits, from the Zoological Society, that 

 was named Microcebus pusillus by Mr. Waterhouse in the second 

 edition of the Catalogue of the Museum of that Society, which agrees 

 with this animal in almost all particulars ; but the ears appear larger 

 and bald, and the fur of the under part of the body whiter — perhaps 

 both particulars arising from its having been preserved in spirits. 

 The length of the feet and the teeth agree ; but the feet, and espe- 

 cially the hands, are white and hairy, while in the dry specimen they 

 are brown and nearly without hair. 



It is sad to observe the persistence with which an error may be 

 endowed. Vigors and Horsfield, in the ' Zoological Journal' in 1828, 

 described an American Douroucouli as a Lemur, under the name of 

 Cheirogaleus commersonii, believing that it came from Madagascar. 

 This error was soon corrected ; but Lesson retains it among the 

 Lemuridse, and re-named it Glicebus rufus ; Schinz, in his ' Systema- 

 tic Catalogue,' published in 1844, still retains it, and calls it Scartes 

 rufus (vol. i. p. 102); and Giebel, 'Die Saugethiei-e,' published in 

 1859, p. 1018, still regards it as a Cheirogaleus. 



10. Lepilemur? I. Geoff. 1851. 



Microcebus, Waterhouse & Peters. 



Cutting teeth "-^y the two front upper longer. Ears elongate, 

 membranaceous, prominent. Foot broad, shorter than the shank. 

 Tail cylindrical, covered with close-set short hair.
