1 captured a cT ad. at Satra in Westmanland, and I have received 

 another from Oland from Mr A. E. Holmgren. The % ad. is un- 

 known to me.

Westbing has only seen imperfectly developed specimens of this 

 species, which however fully agree with specimens in my collection 

 from Germany. France and England, the last received from Cam- 

 bridge under the name of Thorn, sabulosus Blackw. — The tibial 

 joint of the palpus is very like that of A', calcaratus; its lateral 

 process is short, broad, blunt at the apex, the inferior process thin, 

 pointing forwards and outwards, almost parallel to the lateral pro- 

 cess, and its apex is turned inwards, so that, when seen from the 

 upper edge, it has the form of a narrow spur with the hooked point 

 curved inward. The process on the outer margin of the lamina is 

 situated far in front of the tibial joint's lateral process. The bulbus 

 is destitute of any projecting process on the under side; even the 

 fine curved spine, which distinguishes X. calcaratus, is wanting in A", 

 sabulosus. The vulva appears to consist of two fine, somewhat curved, 

 brown furrows rapidly diverging in front, and almost forming 

 a V-shaped or semicircular figure, and of two small depressed black 

 spots immediately behind these ')• 



1) The following, as it would seem, new species, is, like X. sabulosus, di- 

 stinguished by an oblong, elliptical abdomen, considerably more elongated than in 

 most species of the genus Xysticus.
