of Monkey was obtained dead from the proprietor of a Mena- 

 gericj who had purchased it in France, and was ignorant of the 

 country from which it was originally procured. It was a female 

 not fully grown, and had been in his possession for two years, 

 during which period its habits were described as docile, cunning 

 and quiet, a disposition which was not the result of disease, as the 

 yiscera were perfectly sound, and its death was caused by severe 

 cold. With regard to its affinities, Dr. Otto appears somewhat 

 doubtful, whether to constitute from it a new genus characterized 

 by the want of cheek-pouches, by the peculiar form and dis- 

 position of its teeth, and more especially by the singular con- 

 formation of its stomach which we shall presently notice. Taking, 

 however, into consideration, that it agrees in many particulars 

 with several of the species which form M. F. Cuvier's new genus 

 Semnopithecusy and in the expectation that this agreement will be 

 found still more complete when the latter shall have been more 

 thoroughly investigated, he prefers for the present referring it to 

 that groupe of Asiatic Monkeys, with the following generic 

 character : " Bgdy, limbs, and tail, elongated and slender ; face 

 flat; great toe very short ; hairs rather long, very soft, shining; 

 hindermost molar teeth of the lower jaw with five tubercles ; 

 cheek-pouches wanting ; stomach extremely large, cellulous.'* 

 The character of the new species, leiicoprymnus^ is as follows : 

 '' Face, trunk, and extremities blackish ; upper part of the head 

 and back of the neck brown ; throat whitish-cinereous ; crupper 

 and tail whitish ; outer incisors of the lower jaw alate ; surfaces 

 of the molar teeth oblique." 



The entire length of the animal from the end of the snout to 

 the root of the tail is 1 foot 8 inches ; the tail, the extremity of 

 which is eroded, measures 1 foot 6 \ inches; the forehead is 

 broad, and the snout projects comparatively little, forming a 

 facial angle of rather more than 60°. The abdomen is remarkably 

 slender, as are also the fingers and toes in general. Dr. Otto 

 enters with all the minuteness of detail so characteristic of a 

 German description, into every particular of outward form and 

 colour, as well as of internal and anatomical structure. The 

 latter in one essential point, the size and conformation of the
