apex, the outer tooth acute, not longer than the inner. Peduncles of 

 eyes about equal in length to the distance between the eyes. First 

 pair of feet about equal in length to the second and to the length of 

 the body; meros tuberculate; hand thin, broad, smooth, marbled; 

 fingers touching at the extreme tip only; a tooth on the inside of 

 the movable finger near its base. Four hinder pairs short, slender^ 

 cylindrical, setose, except the tarsus, which is smooth and shining, 

 like the manus of the first pair. Carapax and abdomen tomentose 

 above and below." (Lockington.) 



Measurements. — Female, type of E. lucasii, length of carapace 0.36 

 inch (9.1 mm.), width 0.27 inch (6.8 mm.). (Stimpson.) 



Male, type of Peltinia longioculis, length and width of carapace 

 nearly equal, about € mm. (Lockington.) 



Remarks. — In a manuscript note in reference to P. longioculis^ 

 Lockington says: "Stimpson's description of Eucinetops lucasii 

 agrees closely with this. He describes a female, but figures a male 

 specimen which he states may not unlikely be of a different species. 

 My specimen (male) agrees pretty closely with his description of 

 the female, but not with the figure." 



Range. — Cape St. Lucas, Lower California, Mexico.

p. 73 (type-locality. Cape St. Lucas, Lower California, Mexico; type 



not extant). 



Diagnosis. — Horns acute. Fingers of male not gaping. Red spot 

 on dactyls of ambulatories. ^ 



Description of male. — Compared to the female of E. lucasii^ it is 

 smaller and narrower,^^ with the horns of the rostrum acutely pointed, 

 and the external antenna narrower, with the external angle of the 

 first movable article considerably produced. Chelipeds large, much 

 compressed and crested; carpus with two slight crests confluent 

 posteriorly in a projecting angle or point; hand rather broad, flat, 

 tapering to the slender fingers, not gaping. Dactyli of ambulatory 

 legs much shorter than in female lucasii. (Stimpson.) 



CoZor.— Apparently pale orange; a distinct red patch on dactyli of 

 ambulatory feet at middle. (Stimpson.) 



Measurements. — Stunpson does not give any, but according to his 

 figure, which is twice natural size, the length of the carapace to tips 



'• The statement of narrower body is not sustained by the figure, when compared with the measurements 

 f the female type of E. lucasii.
