sent specimens of "C terrestris", agrees with me in considering it iden- 

 tical with D. atropos Walck. 



Drassus segestriformis Duf. 1820 '), which Walckenaer cites under 

 D. atropos in his Ins. Apt., I, confounding it with the right Ccel. 

 atropos, is probably a different species; even if Dtjfour's statement, 

 that the thighs of his spider are entirely destitute of spines, be de- 

 serving of but little weight, yet his mentioning no markings on the 

 abdomen, but describing it as wholly Mack (Conf. Walckenaer's de- 

 scription of the male), seems to indicate that D. segestriformis is a 

 separate species. 



Cambridge has kindly sent me a cf and 9 °f saxatUis 

 Blackw."; the female agrees exactly with German examples of Ccel. 

 atropos (terrestris) ?, and the male presents no essential deviations. The 

 process of the patellar joint, viewed from above and a little from the 

 inner side, is perhaps somewhat more abruptly truncated at its apex 

 than in a German male specimen (for which I am obliged to L. Koch); 

 above, at the base, it is slightly thickened, which is hardly the case 

 in the German specimen. L. Koch however says that this process 

 is "constricted over the base".

 Westr. (Th. Ohlertii Thor.): vid. sup., p. 85. — In Sweden Th. 

 pallens has lately been met with by Dr Tullberg in Skane and by 

 Dr v. Porath in Smaland. — Mr Cambridge thinks that Th. albens 

 Blackw. is but a variety of Th. pallens, an opinion which appears 

 to me very probable.
