is furnished with a few minute denticles or granulations. From 

 beneath the base of this long curved process springs a small black, 

 curved, sharp-pointed spine having the same general direction as 

 the process. At the base of the palpal organs is a short, black, 

 prominent, curved, corneous point rather directed backwards. 



Abdomen dark blackish brown, much obscured by grey hairs ; the 

 markings in this sex almost obsolete, but resembling apparently 

 those of the female. 



The female is slightly larger than the male. The legs have the 

 femora, tibiae, and (at least in one example) the metatarsi more oi* 

 less, but not distinctly, annulated with brown ; in another example 

 the metatarsi were immaculate. The abdomen is clothed, principally 

 on the sides and underneath, with greyish hairs ; the upperside is 

 slightly reddish yellow-brown. The central longitudinal marking 

 is well indicated by a black margin, and its posterior extremity is 

 truncated. The normal angular bars or chevrons between this 

 and the spinners are indicated by two converging rows of black 

 spots or markings continued obliquely on the sides by more or less 

 indistinct lines of black spots. 



Sternum dark yellow-brown, with a not very distinct, short, 

 longitudinal, central, yellowish line. The genital aperture is large 

 and of a very distinct and characteristic form, of which a drawing 

 alone can give any adequate idea. Examples of each sex were 

 found near St. Gervais les Bains at an altitude of over 6000 feet. 



I have thought it well to give a figure of some dissections and 

 a description of this spider, as there is some confusion in respect 

 to its identity with the Lycosa riparia C. L. Koch (Simon, 

 ' Araneides de France ')• An example of this latter spider kindly 

 sent to me by M. Simon for examination is undoubtedly of 

 a quite distinct species from a typical example sent to me by 

 Dr. Ludwig Koch, and bears a closer resemblance in some points 

 to L. prativar/a L. Koch. M. Simon tells me he received it many 

 years ago from Dr. L. Koch, as L. riparia C. L. Koch. There was 

 probably a mistake here somewhere, but Dr. Koch assures me 

 that about the typical example he has sent to me now recently 

 there is no doubt whatever as to its being the true L. riparia oi 

 C. L. Koch. The L. riparia C. L. Koch — Kulczynski — from 

 Austria, is nearly allied to, if not identical with, the type Dr. 

 L. Koch sent to me. On an examination, however, of Kulczynski's 

 type specimen there appeared to me some differences in the form 

 of the palpus and in the structure of the palpal organs ; I do not 

 therefore feel quite certain about it. The spiders formerly recorded 

 (Ann. & Mag. N. H. ser. 4, xvi. pp. 257-258, 1875 ; and ' Spiders 

 of Dorset,' pp. 380-381, 1881) as L. riparia and L. prativaga in 

 England are certain.y all of one species — L. prativaga L. Koch 

 {vide Proc. Dorset ~S&t. Hist, and Antiq. Field -Club, vol. xvi. p 119, 

 1895).
