The spicier here described by Westring is, according to his type- 

 specimens, which he kindly sent to me, identical with that which 

 L. Koch describes under the name of C. trivialis C. Koch, and of 

 which I possess specimens identified by Dr Koch himself. This spe- 

 cies is also by Cambridge considered as the real C. trivialis C. Koch, 

 and it would therefore seem best to preserve to it that name, in 

 preference to C. pollens, which has been assigned by L. Koch to 

 quite another spider. Of C. fallens Ohl. , Dr Ohlert has furnished 

 me with specimens of both sexes; darker specimens of the same species 

 he has sent me under the name of C. phragmitis. (Vid. sup., p. 218). 



Concerning C. trivialis Westr. or C. borealis n., see above p. 

 223. — In C. trivialis C. et L. Koch the tibial joint of the male's 

 palpus has at its extremity, on the outer side, a single, somewhat short 

 anal broad process, tapering towards the apex, which is rounded off 

 and has a slight depression above. This process is of a black or 

 brown colour, except in young specimens (as e. g. Westring's) which 

 have lately changed their skin. The vulva forms a brown or black 

 area, the posterior edge of which, formed by the rima genitalis, 

 is somewhat produced and sinuated (its middlemost portion being 

 larger and more projecting than the lateral); in front of the edge 

 are seen two depressions, and at the very apex of it generally also 

 a small pointlike fovea. 



As regards C. pollens Hahn (Die Arachn., II, p. 10, Taf. 40, 

 fig. 101), it is utterly impossible with any certainty to identify it; 

 nor is it much easier to recognize the spider, which C. Koch (loc. 

 cit., VI, p. 19, Taf. CLXXXV, figg. 443, 444) took to be C. pollens 

 Hahn, and to which he preserved that specific name. The species, 

 which L. Koch (loc. cit.) calls C. pollens Hahn, and which may 

 keep the name, is according to specimens with which he has fur- 

 nished me, identical with C. diversa Cambr. 2 ), of which I possess an 

 English $ ad. through the kindness of Mr Cambridge. The species, 

 as this eminent arachnologist observes, much resembles C. trivialis 



1) According to specimens, with which I have been provided by Mr Cambridge.
