CHIRACANTHIUM NUTRIX. 



Chiiuoanthium Nirraix, Westr., Aran. Suec, p. 878. 



Non. Clubiona nutrix, Blackw., Spid. Great Brit, and Irel. 



About the same size as the f orogoing, and nearly resembling it 

 in form and structure. It may, however, be distinguished by 

 the cephalo-thorax having no markings upon it ; the abdomen 

 also is of a brownish-yellow colour, tinged with red, and has, on 

 the upper side, only an elongated, reddish yellow-brown marking 

 along tho middle of the fore part. The falces are shorter and 

 loss divergent than those of C. carnifex. The digital joint of 

 the male palpus is as long as, or even a little longer than, the radial 

 and cubital joints together, the radial being nearly double the 

 length of the cubital. The digital spur is loss strong, but rather 

 longer, and the angular prominonce on the outer side is less 

 developed, and furthor from the extremity of the joint than in 

 C. carnifex ; the radial apophysis is also stronger and longer, 

 but is similarly cleft at its extremity, which is likowise a little 



An immature female was found by my son, Eobort Jocelyn, 

 among heather at Blox worth, in September, 1877. 



I had previously only met with this spider in Lancashire, and 

 received it from Scotland. The adult male has not yet been found 

 in Britain ; the characters, therefore, of that sex above given, 

 have been taken from examples sent to me by Dr. T. Thorell, 

 from Sweden.* 

 GENUS ANYPH^ENA, Sund. CLUBIONA, Blackw. (in part). 



This genus is also nearly allied to Clubiona, but differs in having 

 a transverse fold in the integument near the middle of the under- 

 side of the abdomen, concealing an opening into a special spiracu- 

 lar organ. The fore part of the cephalo-thorax is also narrower. 

 Legs 1.4.2.3. 



One species only has been found in Great Britain, and it is 

 also abundant in Dorsetshire. 



•Since the above was in press (September, 1878), I have met with both 

 males and females, in the adult state, on fern and heather at Bloxworth, the 

 former box agreeing exactly with the Swedish examples,
