 eyes much shorter than the second, distintly procurved, median eyes their radius or 

 slightly less apart, an equal distance from the lateral eyes which are decidedly smaller. 

 Lateral eyes scarcely their diameter from lower margin of clypeus, an equal distance 

 from eyes of second row. Eyes of second row less than their diameter apart. Quad- 

 rangle of posterior eyes comparatively long, the cephalothorax being less than three 

 and a half times as long. 



Spines beneath tibiae long and distally very fine. Epigynum small, of form shown 

 in pi. 6, f. 2.

This species suggests L. concolor Banks of Lower California. It is a smaller 

 species distinguishable in having tib. -|- pat. IV shorter than the cephalothorax instead 

 of clearly longer; in having a black band at both ends of tib. IV instead of only at 

 one end; in not having the femora, metatarsi and tarsi black beneath, etc. 



ParJosn tunha sp. nov. 



Female — In the types the body is dark throughout, in life clothed with grey hair; 

 the median dorsal stripe of carapace obscure. Legs black excepting tarsi and meta- 

 tarsi, which are dull brown, the latter with three black annuli; sometimes the proximal 

 joints also show the paler color in spots and streaks or in part may be somewhat 

 annulate. Sternum solid black. Abdomen with integument black above excepting an 

 obscure pale mark at base; also black laterally, but the venter paler though with a 

 deep black band between epigynum and spinnerets ; venter in life clothed densely with 

 grey hairs, the dorsum with grey and reddish intermixed with some black. Anterior 

 row of eyes slightly procurved, much shorter than the second row ; median eyes their 

 diameter apart, not fully half as far from the four-fifths as large laterals; the latter 

 twice their diameter from the edge of the clypeus and decidedly more than their 

 diameter from the eyes of second row. Eyes of second row fully their diameter, or 

 slightly more, apart. Two first pairs of spines of anterior tibiae and metatarsi long, 

 slender, overlapping as usual. Armature of chelicerae typical. Epigynum of the 

 sternalis type, but with the expanded quadrate posterior end of septum completely 

 filling the posterior cavity, or nearly so, as shown in pi. 6, f. 3. 



Length, 6 mm. Length of cephalothorax, 3 mm. Length of tib. + pat. I, 2.S mm.; 

 of tib. -f- pat. IV, 3 mm.
