Loc. Loja, 200(» tn,, in Ecuador (P. O. Simons). 



Genu.s Ti:uTiiKAUSTi:s, Sinioii. 

 Teuthraustes oculatus, sp. n. 



? .—-Colour black, vesicle and tarsi ferruginous. 



Carapace with anterior border transverse, but di.stinctly 

 notched in the middle line ; frontal area very sjjarsely 

 granular, mesially grooved, ocular tubercle high ; three 

 distinct lateral eyes ; ocular tubercle, posterior portion of 

 carapace on each side of the median groove, and area round 

 tubercle smooth. 



Anterior five terga quite smooth in the middle, sparsely 

 granular laterally, without trace of enlarged tubercle on eacli 

 side on the po.sterior margin. 



Sterna and tail as in T. nitescens, but the superior caudal 

 keels a little more coarsely granular. 



Chelce as in T. nitescens, but the brachiuni and hand not 

 visibly crested, the latter almost entirely smooth and very 

 obsoletely sculptured. 



(J, — Differs from the male of T. latimanus in being much 

 more finel}' granular throughout, with larger ocular tubercle ; 

 hand much narrower, its width much less than length of 

 fifth caudal segment; fingers longer, immovable considerably 

 longer than its basal width.

Loc. Sinche and Hicbamba, 3000-4000 m. (R 0. Simons). 



Since describing the species known as T. latimanus and 

 T. monticola, the former from Corazon, 12,000 feet, the latter 

 from Machachi, 9000-10/JOO feet, I have seen several repre- 

 sentatives of both forms from iMachachi {E. W/ii/mper)^ 

 which convinces me that the differences are merely sexual. 

 T. nitescens is probably only a subspccific form.
