part, of which is reddish brown, with a little black tooth in the po- 

 sterior margin. The tibial joint of the male's palpi, which is almost 

 double as long as the patellar joint, is inerassated and strongly convex 

 longitudinally on the underside. The patellar joint bears a long, slightly 

 curved bristle of about the same substance as the spines of the legs; 

 the tibial joint has, near its base, another, slightly shorter and more 

 slender bristle; these two bristles are almost parallel.

"Mas junior" of L. alticeps Westr. (p. 118) belongs to the next 

 following species, L. affinis Westr., described by Westring in the 

 Addenda to Aran. Suec, p. 595. 



Though the males of L. alticeps and L. affinis are easily di- 

 stinguished, it is not easy to assign to each of these species its pro- 

 per synonyms. Menge's Bolyphantes alticeps however I refer without 

 hesitation to L. alticeps Sund., Westr., though his description differs 

 in a few particulars from what I believe myself to have observed: for 

 example, according to him the palpus-claw is destitute of teeth 

 (some however appear in the figure) '), and the tarsal claws have only 

 about 10 teeth, whereas I have seen a greater number, 14 — 18 on 

 the first pair of legs. Neither can Ohlert's Boh alpestris, which is 

 stated to have eight teeth on the female's palpal claw, and its head 

 "much elevated and drawn out forwards," be any other than L. alticeps. 

 But such is not the case with Blackwall's L. luteola or alticeps 2 ). It is 

 true that Blackwall's description of the coarse bristle on the patellar 

 joint of the male's palpi agrees better with L. alticeps Sund. than with 

 L. affinis, but Blackwall's figure (fig. 149) nevertheless in certain 

 respects shows a better agreement with L. affinis. In L. alticeps 

 Sund. c? the inferior central eyes are not situated at the extreme end 

 of the head , as in that figure (and in L. affinis) , but somewhat tinder 

 the extremity of the head ; neither does the head rise over the breast

 kleinen Zilhnchen."
