spots; sometimes the vertehral Jine is li^lifer (lian the rest of the 

 ground-colour, which varies iruiu buff to i;rev. There are also 

 specimens without ocelli. Thus, ii female from Chefoo has only two 

 more or less interrupted whitish streaks on eiich side, Ijordered by 

 larger dark brown spols, and a male iVom the same locality resembles 

 very closely the type of E. hrcnrlileijl in its coloration, a continuous 

 white streak extcndiuL;- from lielow tlie eye to the L;roin, edged above 

 by a dark brown baud, which is continued on thi! tail; a second 

 (dorsolateral) white streak above, continuous on (he neck, broken up 

 into ocellar spots on the body. Other specimens are intermediate 

 between these striated examples and the more fre({uent type with 

 nothing but ocelli. Lower parts white.

The sexes are difficult to recognize externally in this species. The 

 males have a larger head and a rather shorter body, biit tlie tail 

 is not or but scarcely swollen at the Ijase and the femoral pores are 

 not larger than in the females. 



Habitat. — Manchuria, Corea, Mongolia, Northern China.

Only about a dozen specimens of this form are known to exist in 

 collections, and it is therefore difficult to decide whether it should 

 rank as a variety of E. ((/v/h.n- or as a distinct species. Co/isideriug 

 the characters which have been adduced in favour of its specific dis- 

 tiuction as either too slight or as occurring also in annectant specimens 

 of E. arguis, I prefer, for the present, to treat it as a variety. 



The latest dehnition is that given l>y Bedriaga (I.e.), and is here 

 repeated, the structui-al characters frmn his synopsis (p. o05), the 

 coloration from his diagnoses (pp. 64:6 and 655) : —
