12 MAMMALIA. 
M. Geoffroy calls those species which have inferior trenchant 
incisors placed on a straight line and less than the canines, Mrpas. 
Their tail is also more slender and not annulated. 
Sim. odipus, L.; 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.(1) 
Mid. rufimanus, Geoff.; Sim. midas, L.; Buff. XV, 13. (The 
Tamarin.) Black, the four extremities yellowish. From 
Guiana. 
Mid. ursulus, Geoff.; Buff. Supp. VIII, 32; Mid. fuscicollis, 
Spix, pl.20. (The Black Tamarin.) All black; reddish waved 
stripes on the back. 
Mid. labiatus, Geoff.; M. 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 Linnzus, 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 Annal. du Mus., XIX, p. 119—122. 
(1) Isuspect the Mid. bicolor, Spix, pl. 24, is merely a variety of the Sim. edipus, 
and his M. mystax of the M. labiatus. 4 
(2) The S. leonina, Humb. Obs. I. pl. 5, is brown, with white lips and black face, 
like this species ; but it appears the hairs of the neck are more thickly set, form- 
ing a mane like that of the Marikina.. Add Mid. chrysopygus, Natterer.
