Ten specimens of this species have been collected by Sowerby on 

 three of his expeditions to the Mongolian frontier, namely, two (Nos. 

 39340 and 39341) from the province of Kansu, the first at a locality 

 6 miles south of San-chow-fu (about 5,100 feet altitude) on June 21, 

 1909, and the second one near Ching-yang-fu (about 3,100 feet) on 

 August 8, 1909; one (No. 49644) at Kuli-hua-cheng, northern Shansi, 

 during May, 1912; and seven at the Imperial Hunting Grounds, 

 Chilili, 65 miles N. E. of Peking during August, 1917. 



They show the usual variations of this species, but none have the 

 subocular forming part of the labial edge, as in the so-called E. 

 hrenchleyi^ nor do any of the specimens approach the other charac- 

 ters attributed to this much debated form. In all the specimens the 

 fronto-nasal is divided, except in No. 49644, nor do':s this specimen 

 have any small scales or granules intercalated on the snout ; in addi- 

 tion, it possesses an unusually small interparietal. Among the other 

 specimens, No. 39340 from LanChow, Kansu, which I have examined 

 very closely for possible relationship to E. multiocellata^ which has 

 also been recorded from Kansu (type specimen of E. planiceps 

 Strauch), has a divided fronto-nasal, and the length of the anterior 

 large supraocular is not greater than its distance from the second 

 loreal. 



It is true that an occasional specimen of E. multiocellata is found 

 with a divided fronto-nasal (Petrograd Mus. No. 5124, from Bal- 

 gantai-gol, Tian-shan, Col. Przhevalski, collector) and that the gran- 

 ules filling the anterior supraocular triangle are unusually large and 

 coarse, but this space itself is not smaller than in typical E. argus^ 

 and the specimen does not otherwise differ from normal individuals 

 of this species. ^^^.^^ ANGUIDAE
