Samofisilus gen. iiov. 



Ccphalochorax wiili general form much as in Trachelas. Sternum broailly trun- 

 cate anteriorly, pointed at caudal end, margltied. Endites not excavated exteriorly, as 

 hroad at middle as at distal end; the disloeclal corner rounded. Labium distally 

 truncate or a little incurved. Lateral eyes on each side well separated, though much 

 closer together than the anterior and posterior medians. Anterior row of eyes straight. 

 Anterior medians smaller than the laterals. Posterior row of eyes slightly recurved, 

 eyes equidistant or nearly so and nearly equal in size, with the laterals equal to the 

 posterior laterals. Quadrangle of median eyes wider behind than in front. Clypeus 

 much wider than the anterior eyes. I'pper margin of furrow of chelicera with three 

 large teeth, of which the median is longest; lower margin with a series of seven or 

 eight teeth, of which the most proximal ones become reduced in si/e. None of the legs 

 scopulate and all lacking terminal tenent hairs. Anterior tibia; armed beneath with 

 four pairs of long spines, the metatarsi with three pairs. Posterior tibia? in middorsal 

 line with a basal and a subapical spine, and each patella with a median spine at 

 distal end above, these dorsal spines smaller than the laterals and ventrals.

Samofisilus />lrliis sp. nov. 



Ffmalf — Carapace chestnut colored, dusky over the sides, eye region, along striiB 

 and over clypeus. Legs light chestnut-brown; femora marked with two wide dark 

 annuli, one at distal end and one submedian, these more or less interrupted above; 

 patella with annuliis about distal half also interrupted above; tibiae with two broad 

 annuli, one at distal end and one between middle and base, these sometimes almost 

 confluent; entire metninrsi dusky or obscurely biannulate. Sternum light chestnut, the 

 cox.T of legs lighter brown. Chelicera." dusky chsctnut. Labium and endites pale across 

 tips, elsewher edark chestnut. Sides of abdomen deep brown or blackish, the dorsum 

 with a series of dark chevron marks ending in the dark of the sides and connected 

 along the middorsal line, the spaces between them on each side yellowish; venter 

 grey. Clypeus twice as high as the diameter of an anterior lateral eye. Anterior 

 median eyes much smaller than the laterals, about their diameter from each lateral eye 

 and considerably farther from each other. Lateral eyes on each side about their radius 

 apart. Posterior row of eyes a little recurved. Posterior median eyes scarcely smaller 

 than the laterals, nearly once and a half their diameter apart and an equal distance 

 from the laterals. F.pigynum as shown in pi. 6 f. \. The spcrmalheca-, which ordi- 

 narily show through the integument as black bodies, are not represented in the figure.

l.ycnsa ferrinilosa sp. nov. 



Carapace brown, paler in a supramarginal line on each side, below which the 



marginal dark band is interrupted, and in a median longitudinal stripe which narrows 



forward and projects in a point between the eyes and again expands between the first 



and secoiul rows; a curved line each side of the median stripe just caudad of the eyes
