(type-locality, Brazil; type in Paris Mus.). 



Diagnosis. Carapace granulate anteriorly. No deep postorbital 

 sulcus. Tooth on merus joints of legs. 



Description. Carapace three-fourths as long as broad; gastro- 

 cardiac sulcus present; surface punctate and around the front and 

 lateral margins finely granulate; margin a raised crenulate line. 

 The front, in dorsal view, appears faintly bilobed; in front view, 

 nearly straight. Upper margin of orbit slightly sinuous and sloping 

 backward and outward. In lower border of orbit below outer angle 

 there is a deep sinus from which a very shallow depression extends 

 backward. Maxilliped broad, ischium and merus subequal in length. 



Arm short and broad, outer surface finely rugose. Wrist bluntly 

 angled, and a little rough along the inner margin. Hand smooth 

 outside, higher than its superior length, margined above for a short 

 distance at the proximal end; on inner face, a few granules near 

 carpal cavity. Fingers moderately gaping, feebly toothed, tips 

 horny. 



Second pair of legs twice as long as carapace. Entrance to cavity 

 between second and third legs densely fringed with hair. Merus 

 joints partly rugose, with a low subterminal tooth above; last two 

 joints pilose. 



Abdomen of male narrow-triangular; appendages of first seg- 

 ment narrow. 



Measurements. Male (15071), length of carapace 12.6, width 

 of same 15.4, fronto-orbital width 10.G mm.
