278 Rev. O. P. Cambridge on some neio 



the females of which I am not acquainted. The margins of 

 the cephalothorax in E. spinosa are granulose only. 



This spider was received in 1870 from Mr. E. Whymper 

 (witli whose name I have connected it) . It was found in two 

 localities of North Greenland in June and August 1867, at 

 and near Jacobshavn, among moss floating on the surface of 

 freshwater pools near the seashore.

I have concluded a specimen of this group, received from 

 Spitzbergen (from the Rev. A. E. Eaton) in June 1874^ to be 

 the Micrypliantes arcticus of Adam White [I. c. supra). It is 

 very similar and very nearly allied to E. longipalpis, Sund., 

 but differs from it in various slight particulars, especially in 

 the much shorter radial joint when compared in length with 

 the cubital ; the digital joint of the palpus is also propor- 

 tionally smaller ; and the spider Itself was rather larger than 

 any example I have yet seen of E. hngipalpis.

So far as a crushed specimen enables me to judge, this 

 spider is larger than E. hngipalpis^ Sund., but closely re- 

 sembles it in colours, general structure, and appearance. 

 One very remarkable character, however, is furnished in the 

 male by the great length and curved form of the spur beneath 

 the fore extremity of the cubital joint of the palpus. This joint 

 considerably exceeds in length the radial; and the spur 

 alluded to is directed forwards, strongly curved, and tapering 

 to a rather fine point ; its length considerably exceeds that of 

 the joint to which it is attached; and its point extends to the 

 middle of the palpal organs, which appeared to be less complex 

 than those of E. longipalpis and others. The specimen from 

 which these notes were taken had been crushed in the process 

 of mounting on a microscopic slide ; so that possibly the 

 apparent near contact of the extremity of the spur with the 

 palpal organs may have arisen merely from the mode of 

 mounting. The great length and form of the spur alluded to 

 distinguishes this species from all others of the group as yet 

 known. 



This spider was one of those found in the late Arctic 

 Expedition. There was, however, no note connected with
