72 MAMMALIA. 



M. Geoffroy calls those species which have inferior trenchant 

 incisors placed on a straight line and less than the canines, Midas. 

 Their tail is also nnore slender and not annulated. 



Shn. cedipics, L.j Buff. XV, 17. (The Pinche.) Grey, 

 waved with brown ; long white hairs on the head which hang 

 behind the ears ; tail slender and red. From the banks of 

 the Amazon.(l) 



3Iid. nifimanus, Geoff.; Sim. midas, L. ; Buff. XV, 13. (The 

 Tamarin.) Black, the four extremities yellowish. From 

 Guiana. 



Mid. ursuluSf Geoff, j Buff. Supp. VIII, 32 j Mid. fuscicoUis, 

 Spix, pi. 20. (The Black Tamarin.) All black ; reddish waved 

 stripes on the back. 



Mid. labiatiis, Geoff.; 31. nigricollis, Spix, 21. (The White- 

 lipped Tamarin.) Black; crupper reddish; circumference of 

 the nose white. (2) 



Sim. rosalia, L.; Buff. XIV, 16. (Lion Monkey or the 

 Marikina.) Yellowish; the head surrounded with a yellow 

 mane ; end of the tail brown. From Surinam. 



Hapale chrysomelas, Pr. Max. lib. ii. (Black Marikina.) 

 Black fore-arms ; upper side of the tail and mane of a golden 

 yellow. 



Sim. argentatus, L.; Buff. XV, 18. (The Mico.) Silver grey, 

 sometimes all white ; tail brown. From the Amazon. 



Lemur, Lin. 



The Lemurs, according to Linnseus, comprehend all the Quadru- 

 mana which have in either jaw incisors differing in number from 

 four, or at least differently directed from those of the Monkeys. 

 This negative character could not fail to embrace every different 

 beings, while it did not even unite those which should be combined. 

 Geoffroy has established several divisions in this genus which 

 are much better characterized. The four thumbs of these animals 

 are well developed and opposable, and the first hind finger is armed 

 with a pointed, raised nail ; all the other nails are flat. Their fur 



collar all white. In some of them, on the contrary, all the white has disappeared. 

 See Anna!, du Mus., XIX, p. 119122. 



(1)1 suspect the Mid. bicolor, Spix, pi. 24, is merely a variety of the Sim. cedipus, 

 and his M. mystax of the M. lahiaius. 



(2) The S. leonina, Humb, Obs. I. pi. 5, is brown, with white lips and black face, 

 like this species ; but it appears the hairs of the neck are more tliickly set, form- 

 ing a mane like that of the Marikina. Add Mid. ckrysopygus, Nattcrer.
