ON NEW AND RARE BRITISH ARACHNIDA. 135 



In E. errata the general colouring is Cephalothorax dark 

 brown, legs dull orange yellow, and the abdomen dull yellow- 

 brown ; the colours of E, omissa being of a darker brown 

 hue on the cephalothorax, the legs clearer yellow, and the 

 abdomen jet black. These colours, however, may in some 

 measure depend upon the age of the specimen and the length 

 of time it had been in spirit of wine. 



The examples of E. errata were found by Dr. A. R. Jackson 

 on Scawfell Pike and Bowfell, Cumberland, at height of 3,210, 

 and 2,960 feet, while so far E. omissa has only been found 

 in a marsh or marsh-like habitat. 



Genus Nov. Collinsia. 



Cephalothorax nearly as broad as long, rounded behind, and 

 tapering to its fore extremity, which is broadly and roundly 

 obtuse; the lateral marginal impressions are obsolete, or almost 

 so ; upper convexity normal ; profile almost uniformly 

 convex ; a very slight impression at the junction of the 

 caput and thorax. The height of the clypeus, which is rather 

 prominent, exceeds half that of the facial space. Eyes in 

 normal position of two transverse curved rows, posterior 

 row slightly curved, the convexity of the curve 

 directed backwards. Those of the central posterior 

 pair appear to be slightly largest of the eight. Legs 

 moderately strong, rather short, 4, 1, 2, 3! (1, 2, and 3 

 do not vary greatly in length) furnished with hairs, excepting 

 a slender bristle-like spine at the extremity of each of the 

 femora, and on each of the genual joints and tibiae. The 

 digital joint of the male palpus has a strong obtuse concave 

 prominence directed backwards at the base of the upper side. 

 Fakes rather long, moderately strong, straight, perpendicular, 

 and furnished with a small single tooth (ending with a slender 

 bristle) on the inner side near their extremity, besides the 

 normal teeth near the fangs.
