SOME NEW AND RARE TRTSH SPIDERS. 



BY DP:NIS R. PACK-BERESFORD, M.R.I. a. 



In the last uutcs on Irish Spiders, which I contributed to 

 the Irish Naturalist in November, 1922, there were unfor- 

 tunately several misprints. This was owing to the fact 

 that my corrected proof was lost in the Post Office fire 

 in the Old Rink shortly before that date. Most of the 

 misprints were sufficiently obvious, but there was one which 

 I should like to take this opportunity of correcting, inas- 

 much as it made a unique little spider, Maro persimilis 

 Camb., of which species only a single specimen has yet 

 been found anywhere, into the quite different genus of 

 Maso. 



I desire next to thank that indefatigable collector, Mr. 

 R. A. Phillips, for a large number of most interesting 

 collections from the South and West of Ireland. Thanks 

 to his industry I am now able to give a long list of new 

 localities for many of the rarer species, and to add three 

 species new to the Irish list. 



I have also to thank Mr. A. W. Stelfox, Mr. Nevin H. 

 Foster, Mr. R. J. Welch, Mr. E. O'Mahony and my brother, 

 Mr. R. J. Pack-Beresford, for collections they have kindly 

 sent me at various times. I wash also specially to thank 

 Dr. A. R. Jackson for naming for me the three species new 

 to Ireland, for confirming many others, and for his invalu- 

 able kind help at all times. In the list which follows the 

 three species new to the Irish list are — 



Oxyptila sanctuaria Camb. 

 Cnephalocotes elegans Camb., and 

 Centromerus arcanus Camb. 



all of which were found by Mr. R. A. Phillips. 



Prosthesima apricorum L. Koch — P. subterranea Koch (Carpenter, 

 List Spid. I.). — Nowhere a common spider, it has occurred mostly as single 

 specimens in Ulster, Leinster and Munster, but has not previously been 

 recorded for Connaught. Mr. R. Welch, however, took a female on Lough 

 Derg, Co. Galway, in 1908, and Mr. N. H. Foster another at Belclare, Co. 

 Mayo, in 1 9 10. I also found three females and several immature males 

 at Ballyquinton Point, Co. Down, in June, 1910, this being the only spot 

 in Ireland I have come across where it seems to be fairly numerous.
