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-
