Plate 44, fig. A. 



Diagnostic characters: Anterolateral margins armed with four 

 acute, spine-like teeth, frontal margin more than half the width of the 

 carapace; chelipeds unequal in the male; carpus entirely and the 

 proximal upper diagonal half of the outer face of the palm set with 

 rows of sharp spines; lower outer diagonal half of palm smooth. 

 Small cheliped with outer face of palm entirely covered with longi- 

 tudinal rows of sharp spine. Brown coloration of fingers not extend- 

 ing upon the palm. 



Type: The "Hassler" Expedition secured the type, a female, at 

 Abrolhos Islands, Brazil, in 30 fms. It is deposited in the Paris 

 Museum. 



Distribution : A rather rare species known from Abrolhos Islands, 

 Brazil, and two specimens taken in Bermuda. The ''Ara" material

 Cuba, February 18, 1923, collected by the ''Ara," WiUiam K. Vander-

Technical description: Carapace 7 mm. long, 10 mm. maximum 

 length; frontal margin 5 mm. wide, incised in the median line and 

 armed with spines along the margin. Carapace roughly hexagonal, 

 decidedly convex longitudinally, a distinct groove running back from 

 the median front onto the gastric region ; urogastric line deep, a short 

 longitudinal groove at either end of it. Anterior three-fourths of the 

 carapace bristling with long, stiff setae, as are also the chelipeds and 

 ambulatories. Posterior fourth of carapace relatively smooth, punc- 

 tate. The frontal margin is armed with eight or ten spines; the 

 superior orbital margin is armed with a row of sharp spines; the in- 

 ferior orbital margin is also set with a row of sharp spines; several 

 of which show in a dorsal view. The anterolateral margin is armed 

 with four acute, slightly forward-directed, widely spaced, horn-color 

 spines, including the postorbital spine. The posterolateral margins 

 are longer than the anterolateral, and converge posteriorly; the pos- 

 terior margin is wide and slightly convex. The male abdominal belt
