238 Rev. 0. P. Cambridge on new 



yet published as Irish no more than eight are peculiar to Ire- 

 land ; and some even of those are obscure and perhaps doubt- 

 ful species. Thus no general work can at present, without 

 a serious misnomer, be entitled either " British Spiders " or 

 " Spiders of Great Britain and Ireland." Our knowledge of 

 Scotch spiders is rapidly advancing, thanks to the fine collections 

 kindly sent to me by Mr. James Hardy and Mr. J. H. W. 

 H. Traill ; will not some resident entomologists in Ireland 

 pay some attention to spiders during their collecting-expedi- 

 tions ? The trouble of collecting and bottling spiders is very 

 slight compared with that of the preservation and setting-out 

 of the Insecta ; and a few bottlefuls collected, even indiscrimi- 

 nately, at different times of the year and in different localities, 

 would soon make us acquainted, at least, with the commoner 

 species. A published list of these might then possibly stir 

 up some one to collect and investigate Irish spiders more 

 thoroughly and systematically. 



I need scarcely add that it will give me great pleasure to 

 receive and determine any spiders sent to me from Ireland.

The determination of the European species of the genus 

 Atypus seems to be a matter of considerable uncertainty, and 

 the subject must be said to be as yet somewhat confused. 

 Upon a close comparison made by Dr. Thorell in 1873 of the 

 type specimen of Mr. Blackwall's figure and description of the 

 male of his A. Sulzeri, sent to him by myself, with the type 

 specimen of A . anaehoreta, Auss. (the latter lent to him by 

 Dr. L. Koch), Dr. Thorell decided that A. Sulzeri, Bl., £ , 

 and A. anaehoreta, Auss., are identical, and (on other grounds) 

 that both are identical with A. affinis, Eichw. 



A female sent to Dr. Thorell, taken by myself in Portland, 

 was decided to be identical with A. piceus, Sulz., and the 

 same as the female of Mr. Blackwall's A. Sulzeri. 



In accordance with the above determination I included two 

 species in my systematic list (I. c. supra), viz. A. piceus, 

 Sulz., = yl. Sulzeri, Bl., $, and A. affinis, Eichw., — A. 

 Sulzeri, B1.,<J .
