HAPALEMUR SIMUS. 47 



"II. Nose broad and truncated. Skull — nose very 

 broad, square, truncated in front; palate scarcely wider 

 behind ; series of grinders wide apart and nearly parallel ; 

 lower jaw weak and narrow in front, with a short sym- 

 physis. Prolemur. 



""Hapalemur simus, sp. nov. (PI. 52) B. M." 



"Back iron-grey , with a rufous tinge ; the hairs black , 

 with a subapical rufous band , and the lower part lead- 

 coloured ; throat whitish ; spot on rump at base of tail 

 yellowish." 



««Hab. Madagascar." 



"This may be Hapalemur olivaceus; but that species is 

 very imperfectly described , and it is said to have a differ- 

 ent form of the hinder parts of the lower jaw; but what 

 the difference is , is not mentioned , and I do not see any 

 difference in the hinder part of the lower jaws of the two 

 species. The front of the jaw in H. griseus is very much 

 more slender and weak than in H. simus. 



"The skull rather solid; nose broad, truncated in front: 

 palate slightly concave, nearly as broad before as behind, 

 the teeth series being nearly parallel : cutting-teeth ^ ; the 

 upper subcylindrical , close by the front side of the ca- 

 nine; inner rather the smallest; lower shelving, in two 

 groups, the four inner much compressed: canines ^ ■ \; 

 upper triangular , conical ; lower rather compressed , with 

 a conical lobe on the front edge. 



"The animal on which the species is established is full- 

 grown but the state of the hinder grinders shows that 

 it had not reached adult age; it shows no sign of sexual 

 organs, but is most probably a female." 



"It died soon after its arrival at the Gardens, and un- 

 fortunately had not had time to recover the effects of its 

 confinement on the voyage." 



"The tips of the long hairs of the fur of the greater 

 part of the body have been Avorn off, leaving only a 

 lead-coloured cottony wool. The head, neck, and outside 

 of limbs , where the tips of the long hairs remain , are
