 Neriene pholcommoides, Cambr. 

 Linyfhia rnoLCOMMOiDES, Cambr. (p. 212). 



During the past summer (1880) I have mot with two adult 

 examples of oach sex of this spider, which I had (I.e.) described 

 as a Zinyphia. A careful examination, however, of the fresh, 

 and much better conditioned examples, leads me to romove it 

 into the genns Neriene, in spite of its logs boing armed with 

 distinct, though slendor, spines. 



The examples now recorded were found on the ground undor 

 shelter of short herbage ; their modo of running is peculiar 

 (though similar to that of many others of the genus Neriene), 

 and swift ; the body is kept quite flat and close to the surface of 

 the grouud, giving tho spider a creeping appearance, quite 

 different from that of any Linyphia I have ever observed. 



The female closely resembles the male in colour and general 

 characters, though the thorax, at tho top of tho posterior slope, 

 is of an even more sub-conical form than that of the male, and 

 gives the cephalo-thorax a very fair resemblance to a limpet 

 shell. The abdomen of the female is larger and projects more 

 over the base of the cephalo-thorax than that of the male. The 

 genital process is of rather large size and prominent. 



From the fresh examples met with I have beon able to make 

 a more satisfactory examination of the eyes, and I now conclude 

 that the interval botweon those of the hind-central pair is more 

 nearly equal to an eye's diameter, being rather larger than I 

 had before bolieved it to be. Tho hoight of the clypeus also 

 appears to equal noarly half that of the facial space. 



Neriene diltjta, Cambr. (p. 437). 



,, demissa, Cambr. (p. 438). 



Eecent observations lead me to believe that the two spiders 

 above named are of the same species. The long slender process 

 connected with the genital aperture of Neriene demissa was over- 

 looked in the female of Neriene diluta owing to tho latter having
