series. I call Westring's species Cryphceca arietina, with reference 

 to the remarkable palpi of the the bulbus projects from its apex 

 an upward- and backward-curved spine, at least as long as the whole 

 of the animal! s body and about as thick as the tarsi; these spines 

 together resemble a pair of rarns-homs, as Westring remarks. 



Hahnia pratensis C. Koch 1841 (Die Arachn., VIII, p. 64, PI. 

 CCLXX, fig. 639) is by Blackwall (and Menge) referred to Ag. 

 elegans Blackw., by Westring to his H. pratensis or Crypha'ca arie- 

 tina nob. It appears to me probable, that Blackwall and Menge 

 are right; but as this is not quite certain, for Koch was not acquaint- 

 ed with the male, and says nothing either about the relative size 

 of the eyes or about the spine-armature of the legs, I think it is 

 best to drop Koch's specific name, and to accept the nearly contem- 

 poraneous one of Blackwall, and thus to call Blackwall's and Men- 

 ge's species: Hahnia elegans (Blackw.) 1841. 



Westring has kindly sent me for examination the only hitherto 

 discovered specimens of his H. pratensis; Cambridge has obligingly 

 given me a ? of H. elegans from England. 



Among some unidentified spiders communicated to me by Prof. 

 Canestrini, is a male specimen of a Cryphceca, which also is pecu- 

 liarly remarkable for the structure of its palpi: the lamina bulbi 

 is very large and exhibits, in the upwards turned inner edge, to- 

 wards the apex, a large and very deep excision, from the bottom of 

 which proceeds a very long and slender process, broadest and lamellar 

 at its base, and curving upwards and backwards, that reaches about 

 to the middle of the tibial joint: above this joint it is met by a 

 long, fine, black spine proceeding from the posterior extremity of the 

 bulbus, at first curving upwards, but immediately afterwards forward, 

 inside the tibial joint, which spine joins the process, lying close to 

 (within?) it; the tibial joint has a blunt tooth near the apex, on 

 the outer side. I call this species Cryphceca miraMis ')•
