17. Otomys cUvinoram^ sp. n. 



? . 1151. Rombo, 5300'. 



A member of the irror.itus group, with broad nasals and 

 seven laminje in m*. 



Oolour quite different from that of the previous species, 

 the whole back being of a uniform dark cinnamon-brown 

 instead of the coarsely lined and more butFy colour of the 

 common form. Dark rings to the hairs scarcely apparent, 

 brown, not black ; light rings cinnamon. Basal four-tifihs ot' 

 the hairs of a rather paler shade of grey than in aiujoniensis. 

 Tail shorter than in average specimens of that animal. 



Skull with a markedly broader interorbital space than in 

 other forms, the su[)raorbital beads almost obsolete for their 

 anterior half, where they are so strong and well defined in 

 angi niensis. Posteriorly they are well developed and strongly 

 and an-^'ularly divergent over the front part of the brain-case, 

 from which point they again evenly converge backward. In 

 angonieusis they form an even ovnl outline, a postorbital 

 angle being but rarely indicated. Nasals very broad ante- 

 riorly, the transition to the narrower part marked by a more 

 distinct angie than in the previous species.
