Dimensions of the type : — 



Forearm 60 mm. 



Head and body 89 ; fail 55. Metacarpus of tliird digit 63, 

 of fifth lU. 



Skull : greatest length 24'8 ; basi-sinnal length 10' 7. 



Although in all essential characters this hat appears to be 

 identical with the S.-European T. teniotis, the difference in 

 its colour is sufficiently marked to render a suhspecific name 

 advisable for it, especially when tiie immense difference in 

 locality is considered. 



3. Tupaia helangeri chinensis, And. 



S . 452, 453, 484, 534, 568, 570 ; ? . 415. Li-kiang 

 Range, 27° 30'. 9000-11,000'. 



(J. 626. Hills east of Li-kiang Valley, 27°. 10,000'. 



(?. 402. Mekong-Salween divide, 27° 30'. 9000- 

 10,000'. 



? . 30. Mekong Valley, 27° 30'. 5000'. 



Modern specimens from Ponsee, Kakhyen Hills, tlie type- 

 locality of chinensis, would be of service in identifying 

 Atiderson*s species with certainty ; but there is little doubt 

 that the present specimens are referable to it. 



4. Scaptonyx fusicaudatns affinis^ Thos. 



c?. 33. Mekong-Salween divide, 28° N. 7000-8000'. 



Practically a topotype of the subspecies, and oidy the 

 second specimen of this remarkable genus that the Museum 

 has received. 



5. Nasillus investigator, sp. n. 



cJ. 185; ?. 182, 183, 184, 186, 312. Kiu-kiang-Sal- 

 ween divide, 28° N. 11,000'. 



? . 217. Sahveen-Mekong divide, 28° N. 14,000'. 



P^xternally quite like N. gracilis — indeed, all tiie members 

 of the three genera Uropsilus^ Rhynckonax, and Nasillus are 

 hardly distinguishable from each other. 



Essential characters of the dentition as in JS. gracilis^ the 

 formula the same in all the specimens. Skull, however, 

 conspicuously larger, both longer and, especially, broader, 

 the brain-case much wider.
