This animal closely resembles the preceding. The most 

 conspicuous points of distinction exist in the round form 

 of the eyes of this species ; in the first pair of legs, the 

 wrist of which has not the infero-distal extremity pro- 

 duced quite so long ; and in the second pair the hand is 

 not so oval, but tapers more to the extremity, and has the 

 palm defined and marked by a few indentations rather 

 than teeth. The terminal caudal plate narrows suddenly 

 for some distance before it approaches the apex. 



This species was first taken by Savigny when in Egypt 

 with the French army. In this country a specimen, 

 taken by Mr. Edward of Banff, was described by Mr. 

 Spence Bate in the Synopsis of the British Edriophthal-
