,1905,] OF THE GEKTUS RHIXOLOPHUS. i 99 



(6) Light pliaso, : one ad. ; Darjeeling ; teeth slightly worn ; 

 skin : — Above inclining to " clay" ; a strongly marked, deep brown 

 horse-shoe patch ; base of hairs and fnr of under side almost 

 '' cream-buft'." 



(2) Specimens from Ceylon ami S. India. — [a) Bark phase: 

 thi-ee adult individuals ; Ceylon ; teeth rather slightly worn ; 

 skins : — Upper side a shade of brown, darker and duller than 

 "mars-brown"; horse-shoe patch more or less effaced; base of 

 hairs " drab," with a tinge of '• ecru-drab " ; under side " wood- 

 brown " or light " drab." — This is Kelaart's lih. cinerascens. 



A skin (ad., January, teeth xmworn) from Sirzi, Kanara, comes 

 extremely near to the last-mentioned specimen, being only a little 

 dai'ker. A spirit-specimen from Nilghiri seems to be of very 

 much the same coloiu-. 



{h) Intermediate stage : cJ ad. ; January ; Sirzi, Kanara ; teeth 

 unworn. Upper side between " russet " and " mars-brown " ; base 

 of hairs " ecru-drab " ; under side almost " clay." — This is Kelaart's 

 Rh. rammaniha. 



(c) Red, phase : one ad. ; Ceylon ; teeth worn ; skin : — Above 

 light " hazel " with a tinge of " orange-rufous " ; horse-shoe patch 

 almost obliterated ; base of haii-s and under side of body light 

 " orange- rufous." — This is Kelaart's Rh. ruhidus. 



A skin ( c? ad., Februaiy, teeth unworn) from Jella-pur, Kanara, 

 represents the extreme of light colour : uppei- side next to " tawny- 

 ochi-aceous" ; base of hairs and fur of under side almost " orange- 

 ochraceous." 



Conclusions : — The dark phase in specimens from the Himalayas 

 (Nepal, Darjeeling) is of a richer brown, more tinged with i-usset, 

 than in specimens from Ceylon and S. India (Kanara, ISTilghiri). 

 The light phase, in specimens from the Himalayas, seems to be 

 more inclining to " clay " ; in specimens from Ceylon and S. India 

 more " hazel " or " tawny-ochraceous." I do not think the series 

 examined affords evidence conclusive enough to justify the sepa- 

 ration of a Himalaj^an "race" and a southern (Ceylonese and 

 )S. Indian) " race." In all the other characters (external, cranial, 

 dental; variation in general size) there is no appreciable dif- 

 ference. If they were to be separated subspecifically, the southern 

 form would have to stand as " Rh. rouxi ruhidus Kelaart," the 

 Himalayan as " Rh. rouxi typ)icus." 



Measurements. On p. 100, 



Distribution. Himalayas (Darjeeling, Nepal, Masuri). S. India 

 (Nilghiri, Kanara) and Ceylon. 



Remarks. Of the two forms here recognised, Rh. rouxi sinicus 

 and Rh. rouxi typicus, the former, as coming nearest to Rh. 

 horneensis, is no doubt the more primitive. The rouxi-tj-^e, 

 thei'efore, has spread from an eastern point of the continent 

 westwards, through the Himalayas, down the Indian Peninsula,, 

 to Ceylon.
