Dr L. Koch. In tbis, as in L. monticola the cephalothorax is 

 equal in length to patella + tibia of the 4 th pair, and its central 

 band is equably narrowed forwards; but the narrow lateral bands 

 are, in front, broken off in two places, and thus in this species form 

 patches; the form of the vulva is so different, that this spider cannot 

 be aggregated to the L. monticola-group. The vulva indeed consists of 

 a little low, depressed area, which is elongated and very narrow in 

 front, and widens rapidly behind, where it is terminated on either 

 side by an almost semicircular, fine, raised border; throughout the 

 whole area extends a septum, very narrow in front, but triangu- 

 larly widened and slightly depressed behind. — The species is ra- 

 ther a Leimonia C. Koch than a Pardosa, to which sub-genus it is 

 referred by C. Koch. L. proximo, bears assuredly but little rela- 

 tionship to Lyc. arenaria Sav. et Aud. (Descr. de l'Egypte, 2 e I3d., 

 p. 367, PI. IV, fig. 3) from the Desert near Rosetta in Egypt, under 

 which species it is classed by Simon (H. N. d. Araignees, p. 514). 



Giebel (Zur Schweitzer. Spinnen-fauna, p. 440) has described, 

 under the name of Pardosa obscura, a spider (from the Furka and 

 La Flegere), which he considers to be most nearly allied to L. mon- 

 ticola in size and form ; the upper part of the cephalothorax is stated 

 to be of a deep blackish brown, without any markings.
