A very large species of a buffy-yellovvish colour, with sliort 

 velvety fur. 



Size very large, the skull decidedly larger than tliut of 

 O. Mechowi, the largest species of the genus hitherto described. 

 Fur close, short, and crisp ; hairs of back about 7 mm. in 

 length. A few scattered longer bristles present on sides and 

 rump. General colour above uniform buffy (between buff 

 and clay-colour of Ridgvvay), the hairs whitish at their 

 extreme bases, then dull slaty, then buffy, their extreme tips 

 inconspicuously darker. Under surface dull greyish white, 

 with a silvery gloss, not defined at all from the colour of 

 the sides, the hairs whitish to their roots. Head like body, 

 but the muzzle darker, with soiled patches on each side of 

 the mouth, as in G. Mechoici, Upper surface of hands and 

 feet almost naked, the few hairs whitish. Tail-hairs long, 

 dull whitish ; extreme tip of tail naked, warty, but whether 

 this is natural or due to accidetit we are not able to say. 



Skull as compared with that of O. J\Iechowi decidedly 

 longer, although in the single specimen the basilar suture is 

 not closed, while it is in the two adult specimens of G. Mechowi 

 before us. Nasals broad and heavy. Supraorbital region 

 rounded, broad, and expanded, the region just behind the 

 rudimentary postorbital processes markedly inflated; as a 

 result the greatest interorbital breadth is greater than the 

 least breadth across the brain-case above the meatus, the 

 converse being the case in G. Mechowi. Zygomata broadly 

 expanded, thicker and heavier than in the allied species. 

 Anteorbital foramina about equally broad and high. Palatal 

 foramina minute, situated about a quarter of an inch in front 

 of the anterior cheek-tooth (close to it in G. Mechowi). 

 Posterior palate short, parallel-sided. Bullae with the part
