therefore renamed our spider L. mediocre^ Kulcz. Menge's 

 original figures^ are, however, rather vague and uncertain, 

 and I personally should not like to say that they represented, 

 or did not represent, one spider which is the L. straviincuni^ 

 Menge-Simon. M. Simon- describes both sexes, but onl}' 

 figures the male. He states that the species occurs in the 

 South of France, in Prussia, and in Denmark. 



To these European localities Dr. de Lessert'^ adds Switzer- 

 land, as he there found this species on the mossy and lichen- 

 covered trunks of lime trees near Lavign}-. 



Bosenberg* describes the female, and gives a figure of the 

 vulva. I do not think this figure refers to the present species, 

 and indeed Bosenberg states that his knowledge of the species 

 was obtained from Menge and Bertkau. The Rev. O. Pickard- 

 Cambridge^ has already figured one of the I^ambay males. 



Even more interesting than the above species was the 

 capture of Erigone capra, Sim. These specimens, which Mr. 

 Pack-Beresford sent to me at the beginning of the present 

 year, consisted of four males and a female, w^hich had been 

 found by Mr. R. Welch on the banks of the Ulster Canal, near 

 Monaghau, on October 12th, 1909. The structure of the palpi 

 seemed to me extremely like that of E. capra, Sim., as given 

 by Professor Kulczyn.ski in his excellent monograph,^ and on 

 sending a specimen to him he at once recognized it as belong- 

 ing to that species. This was confirmed by Mr. Cambridge. 

 The species is for all that very close to several others, so I here 

 venture to give some figures which will help arachnologists 

 to diagnose it when found. First, as to Vn^fcinalc. I must confess 

 I can find nothing at all striking about it. The vulva would do 

 very well for that of several other species. I have, however, 

 figured it, and also given drawings of extreme examples of 

 the vulvae of its two nearest allies. In sketching these
