JJentition and sla'dl (figs. 47 A', E', C, D', jj. 579), — Canines 

 shorler than in other species of the genus, tliose in upper jaw 

 barely exceeding p^ in height, those in lower jaw conspicuously 

 lower than p^ (see fig. 47 D'). p^-m' and Pj-m^ much larger than 

 in other species (compare figs. 47 A' and B' with A and B) and with 

 considerably higher and sharper cusps. Outer and inner ridge of 

 j)^ completely fused anteriorly (as in other species), those of p^ 

 obscurely separated (fused iu other species), those of p^ deeply and 

 widely separated (fused in other species, compare fi^. 47 C with 

 C) ; inner ridge of p^ raised anteriorly as a conical cusp nearly as 

 liigh as outer ridge, inner ridge of p"* similarly conical and about 

 half as high as outer ridge; antero-internal base of p^ more pro- 

 minent and ledge-like than in other species, m'-^ little more than 

 twice the size of p\ m^ subequal to p,. — Skull in general aspect and 

 even in size very similar to that of M. junnir/Jttoui, but postdcntal 

 palate distinctly narrower and with lateral margins more rapidly 

 converging antero-posterioily, interorbital region broader, and (no 

 doubt owing to Ihe much heavier dentition) temporal ridges fused 

 in median line to form a low sagittal crest, zygomatic arches deeper 

 and tQOre stronglj" curved uiiward posteriori}- (stronger fascia tem- 

 poralis), coronoid process higher and broader, and angular process 

 more prominently developed. 



Fur. — Slightly longer and fuller than in foregoing species. 

 Length, back 12, belly 8, foreneck 12 mm. ( $ yg. ad.). Distri- 

 bution of fur as in M. wroughioni. 



Colony ( 2 yg. ad., type). — Back njjproximately Prout's brown, 

 gradually lightening to a somewhat paler tinge of brown on nape 

 of neck and crown ; bases of hairs dull isabella or wood-brown. 

 Breast and belly drab. Foreneck similar, but washed with a very 

 pale tinge of tawny-olive.

ih/pe, in the Lisbon Museum (Reg. no. 449), a mounted young 

 adult female, skull separate, collected by Sr. Pires (received in 

 1868). The type is the only specimen on record (March, 1911).
