Elliot New Mammals from Mexico and San Domingo. 235 



Skull : Total length, 59 ; Hensel, 50 ; zygomatic width, 26 ; interorbital 

 width, 12; palatal length, 26 ; median length of nasals 23; width poste 

 riorly, 4; width anteriorly, 7; length of upper toothrow, 8; length of man 

 dible, 47 ; of lower toothrow, 8. 



Remarks. This species does not seem to require comparison with any 

 other known. It belongs to that section of the genus without nasal pads 

 and is about the size of 0. latifrons but with somewhat differently propor 

 tioned tail and feet. The specimens were procured by Messrs. Heller and 

 Barber.

 lector's No. 4092.

 heavy; nasals long, widening greatly anteriorly; zygomata broad ante 

 riorly ; palatal arch pointed but not acute ; pterygoids graduated to acute 

 point; incisors large, heavy, curved ; mandible heavy, compact. 



Color. Entire upperparts and sides blackish seal brown, more black 

 than brown ; underparts dark hair brown ; numerous white hairs on rump 

 at base of tail and all over the underparts, so thickly gathered toward base 

 of tail beneath as to cause that part to appear white. Hands and feet very 

 dark seal brown ; tail blackish, naked ; claws very long, curved, horn 

 color. 



Measurements. Total length, 361 ; tail vertebrae, 90; hind foot, 54 ; ear,

 width anteriorly, 10 ; length of upper toothrow, 14 ; length of mandible to 

 tip of incisors, 53 ; of lower toothrow, 13. 



Remarks. This species by its peculiar soft woolly coat differs from the 

 other described forms and would seem to be easily recognizable. It is 

 somewhat larger than H. hispidus, but the hair of that species is harsh as 

 its name indicates. The specimens were obtained by Messrs. Heller and 

 Barber.
