26 Rev. F. O. Pickard-Cambridge on British Spiders, 



Including, then, only those species which are described or 

 recorded in this paper, we have three species new to science 

 and seven species added to the British list. 



Through the courtesy of Mr. W. A. Luff, of Guernsey, I 

 have been enabled to draw up a list of the spiders of the 

 Channel Islands, which will be published in the ' Transactions 

 of the Guernsey Society of Natural Science and Local 

 Research.' 



This list will include the names of all species recorded 

 from the year 1863 up to the present time, with localities, 

 the names of the captors, or the authority who vouches for 

 the occurrence of each species. 



Though not geographically, nor even geologically, really 

 connected so closely with the British Islands as with the 

 coast of Normandy, it has been deemed advisable to include 

 the Aiachnidal fauna of these islands in a list supplementary 

 to that of Great Britain. 



There are at present 116 species recorded, while one only 

 of these {Heho^yhanus Cambridgei, Sim.) has not been 

 hitherto found on the English side of the Channel. 



Several new species have been added to the list by 

 Messrs. Warburton, Luff, and others, noticeably Salticus 

 formicarius^ Wlk., Scytodes thoracica^ Latr., and Asagena 

 phalerata^ Panz. 



Three Species new to Science and Seven neio to the 

 British List. 



Genus Agrceca, Westw. 



Agrceca littoralis, sp. n. (PI. III. figs. 15, a, b, c, d, e.) 



Length of adult female 6 millim., or 2| lines. 



Ceyjhalothorax, caput, legs, and sternum pale orange. 

 Abdomen dull brown, with three narrow pale bands con- 

 verging towards the spinners. 



Cephalothorax oval-elongate, with two dusky bands on 

 either side of the deeply indented central stria, formed by 

 suffusion of the lateral strige. 



Eyes small, occupying a transverse oblong area. Posterior 

 row curved, convexity backwards ; eyes equal, equidistant, 

 rather more than one diameter apart. x\nterior row strongly 

 curved, convexity backwards, occupying a narrower transverse 

 space than the posterior row, almost equidistant ; centrals 

 much smaller, a quarter of a diameter apart. Ocular area 

 set with curving black bristles. All eight eyes situate on 

 black spots.
