AET. 25 CHINESE AMPHIBIAISrS AND REPTILES STEJNEGER 51 



Variation. — Two additional speciments (Nos. 60864—5), collected 

 by Mr. Sowerby with the type, agree with it in most details as de- 

 scribed above; in fact, there is surprisingly little variation. In the 

 head scales the most noteworthly diti'erence consists in the relatively 

 smaller size of the fronto-nasal, the supranasals in both these speci- 

 mens being l:)roadly in contact behind the rostral. In both the sec- 

 ond loreal is in contact with the second and third labials. All three 

 specimens have a well-developed postnasal, two postmentals, two 

 pairs of nuchals, and 24 scale rows. The dorsal longitudinal rows 

 consist of 48 scales in one and 50 in the other; one has 15 scales 

 under fourth toe, the other has 13. The enlarged postfemoral scales 

 are more localized as " patches " and are scarcely as large relatively 

 as in the type. The postanal tubercle scale is scarcely recognizable. 



Remarks. — This northern species presents characters which in their 

 combination give it a central or, in appearance at least, an inter- 

 mediate position between the Eume^es of China and Japan. In some 

 respects it recalls E. latlscutatus., but the double postmental, longer 

 snout, fewer scale rows, and especially the different arrangement of 

 the two large temporals are features more than sufficient to sepa- 

 j-ate them. With E. elegans it shares the enlarged post femorais, the 

 postnasal, and the unspecialized granulation of the soles, but the 

 latter has only one postmental, one pair of nuchals, more numerous 

 scales under the fourth toe, and a temporal scalation like E. 

 Jatiscutatus. It agrees with E, chinensis in having two postmentals 

 and in the temporal scalation, but it has a postnasal, enlarged post- 

 femorals, and the unspecialized foot soles. 



This is the most northern record of a skink in China. It is pos- 

 sible that the E. marginatus reported by Elpatjewsky and Sabane- 

 jew,*- or E. Jatiscutatus^ as the specimens have been determined by 

 Xikolski,*^ collected at Olga and St. Vladimir Bays and at Imperator 

 Bay on the Ussuri coast of Siberia, may be this species. On the 

 other hand, it is not impossible that true E. Jatiscutatus may have 

 been accidentally introduced from Japan to the opposite coast of 

 the Sea of Japan.
