the male, and the abdomen was of the male form. I have seen a somewhat similar 

 form in an exotic spider, but never before among the many thousands of British 

 spiders I have had occasion to examine. 



In all probability this specimen will still be preserved in the Cam- 

 bridge collection, now (or presently to be) in the Hope Museum at 

 Oxford. 



Dr Jackson mentions this spider in a list of the spiders of Glamorgan 

 {Cardiff Nat. Soc. Trans., Vol. xxxix. 1907). Like Cambridge he says 

 the caput is the caput of a male, but he does not mention the abdomen. 



Poprhomma pallidum Jacks. Jackson: Trans. Nat. Hist. Soc. 

 Northd. etc.. Vol. I. (new series), part iii, p. 384 {sub P. oblongum Bl.). 



A gynandrous specimen taken at Hexham. It has one male palpus, one female 

 palpus, and a distorted epigyne. 



Probably this specimen is still in existence, but Dr Jackson is on 

 active service and his collection for the time being inaccessible : so it is 

 impossible to say whether this gynandromorph falls into Class 1 or 3.

 Northd. etc., vol. ill (new series), part ii, p. 435. 



A fine gynandrous form occurred at Cudham at the end of May (1908). In this 

 specimen the right palpus was of the male form with well-developed palpal organs. 

 The left palpus was of the female type. The epigyne was large but asymmetrical. 

 The central portion was of the normal female type, and so was the left part of the 

 scapus. The right portion of the scapus was quite short. Thus the specimen was 

 male on the right side and female on the left.

No figure or description is given — merely the record of the capture 

 (in Dorset) of a ' hermaphrodite ' of this species. It is, however, im- 

 portant as being the only definite record of a gynandrous spider which 

 does not belong to the family of the Linyphiidae. 



iv. I believe Dr Thorell somewhere casually records the occurrence 

 of a ' hermaphrodite ' of the family Lycosidae {Lycosa sp.), but I cannot 

 trace the reference. The authentic cases here included may be classified 

 thus: 



Linyphiidae : 



§ LInyphiina — 2 species. 



Leptyphantes pallidus Cb. 



Porrhomma pallidum Jacks. 

 § Hilairina — 1 species (twice). 



Hilaira excisa Cb.
