SCIENTIIIC RESULTS FROM THE MAMMAL SURVEY. 729 



palmarum group as compared with the rougher, more ragged- 

 looking, fur of the jungle dwellers is a better guide to diagnosis 

 than size of the respective skulls. 



The following are descriptions of the two new forms : — 



FUNAMBULUS THOMASI, sp. nOV. 



A Funambulus of the tristriatus group, slightly smaller than F. 

 tristriatus and numarms, and considerably smaller than F. wroughto7ii. 



Fur about 8 mm. long, fine but not so silky as in tristriatus, the 

 coat having a rougher appearance. General colour of body apart 

 from the dorsal area grey grizzled with ochraceous, less warm in tone 

 than in wwrnarms ; saddle patch, approaching "chestnut brown," 

 showing evidences, in two specimens, of the presumably seasonal 

 change to black ; three longitudinal dorsal stripes, white or cream, the 

 central continued farther forward than in tristriatus, more as in 

 numarius. Under surface bufiy white. Face mixed golden and 

 ferruginous. Tarsus faintly buffy. General tint of hind-feet a 

 colder grey than the ground colour of the body ; fine fringe of hairs 

 edging the soles greyish or silvery white, not buffy or ochraceous, 

 as in tristriatus and numarius. Tail less bushy than in tristriatus, as 

 in ntimarius, and relatively shorter than in either species ; above, 

 darkly grizzled ; below, with the characteristic orange midrib. 



Skull of about the same size as in numarius, biit rather broader 

 and lower ; braincase less arched. Upper tooth-row consistently 

 shorter, and breadth of palate conspicuously less, than in numarius. 



Dimensions of type (as recorded by the Collector) : — 



Head and body, 147 ; tail, 130 ; hind-foot, 35 ; ears, 15. 



Skull: greatest length, 41; condylo-incisive leng*th, 37*6; 

 zygomatic breadth, 24-2; length of nasals, 13; breadth of brain- 

 case above meatus, 17 ; interorbital breadth, 13; palatilar length, 

 18-1 ; breadth of palate between molars, 5-2 ; diastema, 9-5 ; length 

 of bullee on an antero-posterior line, 7*8 ; upper tooth-row, 7*2. 



Hah. Khandalla, Bombay Presidency. Alt. 2,000 feet. 



Type. Adult female. B.M. No. 19. G. 3. 50. Original No. 107. 

 Collected 11th April 1918, and presented to the National Museum 

 by Captain Philip Gosse, R.A.M.C. 



Captain Gosse collected five specimens, two males and three 

 females, in addition to which we have examined two specimens from 

 Thana, in the National Collection, unfortunately without date, 

 which seem to be referable to this species. Of the five Khandalla 

 specimens, collected between February and April, two April speci- 

 mens are already beginning to assume the dark " summer " cDlouring ; 

 while the two additional specimens from Thana are in full " summer " 

 coat, with black saddle-patch and deep ferruginous colouring on 

 the face. 



We have pleasure in naming the species aftei Mr. Oldfield Thomas .
