Dr. Einar Loimberg — Notes on Arctonyx. 323 



Mr. D. Sjolancler. The skull of tliis one is provided with a 

 small j^ and a similar pi on both side.«, thus agreeing with 

 Milne-Edwards^s specimen. The latter is somewhat larger 

 than our specimen, which, however, may be due to the fact 

 that the specimen from Minshan is a female. The absolute 

 identity is not proved, but the close relationship is apparent, 

 andj as this Arctonyx is without nam % I take the liberty of 

 dedicating it to tlie author quoted. The specimen from 

 Kansu, whicli is to be regarded as the type, may be described 

 as follows : — 



General colour much darker even than that of A. I. ohscnrus 

 from Eastern Tliibet — in fact, black above, only grizzled, 

 with brownish-white tips to the hairs on a patch on the 

 upper neck and on the hind-quarters, the white underfur 

 being quite covered by the entirely black hairs. Thecreamy- 

 wliite fronto-nasal band practically ceases a little behind the 

 eyes, but is to some extent continued bj some whitish-tipped 

 hairs wliich are scattered mesially to the above-mentioned 

 grizzled patch on the upper neck. The black band through 

 the eye extends forwards to the edge of the upper lip, which 

 is brownish black to the angle of the mouth, and there con- 

 tinuous with the black of the chin and the interramial space. 

 The light mark below the eye consists of a horizontal 

 brownisli-white streak, more brownish in its posterior part. 

 Tiie ear-rim is rather broadly pure white. The light throat- 

 patch is creamy white, thus lighter or more whitish than the 

 same of A. obscuruSj according to Milne-Ed wards's figure of 

 the latter. The lower parts behind the throat are black, with 

 a sparse brownish-grey underfur on the belly. Legs and feet 

 black, claws pale horn-coloured. Tail brownish white 

 basally, quite white towards the tip. 



Head and body 68, tail 14 cm. 



Skull: condylo-basal length 123 mm.; basal length 112; 

 greatest breadth 70 ; interorbital breadth 27 ; palate-length 

 to one of the posterior corners 90*5, mesially 79; breadth 

 of brain-case 47'6 ; mastoid breadth 69; greatest diameter of 

 on' 13-8. 



Thomas, in 1911, described a new subspecies — Arctonyx 

 leucokennis orestes — from Tsin-ling Mountains, fS.W. Shen>i. 

 This is evidently very different from the Kansu race as well 

 with regard to the colour-pattern as with regard to size. In 

 opposition to the specimen from Minslian, !S. Kansu, which 

 appears to be one of the daikest, A. I. orestes is very light- 

 coloured, with white upper lip, white interramial space, etc., 

 and with the back "mure broadly W'ashed with whitish than
