ON NEW AND RARE BRITISH SPIDERS. 1 53 



Leptyphantes Whympfiri, F. O. P.-Cambr. Fig. 5. 



Both sexes received from Dr. A. R. Jackson in 1902, by 

 whom they were found at the top of Scafell, Cumberland. 

 The female has not, I believe, been before recorded. I have, 

 therefore, added (postea, p. 164) a short description of it. 



Leptyphantes acceptus, sp. n. Fig. 4. 



An adult example of each sex of this spider, which 

 appears to be undescribed, was found at Bloxworth. A 

 description is appended (postea, p. 163). 



Porrhomma egeria, Sim. 



An adult female of this spider was taken by myself in the 

 New Forest in 1895, but was overlooked at the time. An 

 example of the same sex was also received in 1902 from 

 near Huddersfield found by Mr. W. Falconer. 



Porrhomma miser, Cambr. 



Leptyphantes miser, Cambr. List of Brit, and Ir. Spid., 

 p. 29. 



This spider seems to be certainly not a Leptyphantes. 

 M. Simon thinks it should be transferred to Tmeticus, and 

 F. O. P.-Cambridge includes it in his genus Hillhousia 

 (Ann. Mag., N.H., ser. 6, Vol. XIII., p. 90) ; but it 

 appears to me to belong more properly to Porrhoimna. 

 The spider, described and recorded by IM. Simon as 

 Leptyphantes miser, Cambr. (Arach. de France, torn, v., 

 p. 321), is of quite another species. I have received 

 examples of L. miser, Cambr., from South Wales taken by 

 Dr. Randall Jackson, and have had much difficulty and 

 hesitation in the determination of these exampks, as in 

 some of them the form of sternum is almost exactly like 

 that of Opistoxys, Sim., while others agree with the normal 

 form of Porrhomma. There also seems to be some slight 

 variation in the structure of the palpal organs ; but whether 

 the result of an examination of a longer series of examples 

 would justify a specific separation is uncertain.
