Diagnosis. — Margins of rostrum with angular interruptions. Areola 

 broad. Male with hooks on the ischiopodites of the third and fourth 

 walking legs. First pleopod of first-form male bearing all five pro- 

 cesses; caudal process consisting of three distinct parts — a caudolateral 

 knob, a more mesial curved platelike structure partially enclosing the 

 third part, which is a small tootlilike structure. 



Male holotype (form I). — Carapace subovate, compressed laterally. 

 Abdomen only slightlj'" narrower than cephalothorax. In region of 

 caudodorsal margin of cervical groove, width slightly greater than 

 d(!pth. Greatest width of carapace just posterior to caudodorsal 

 margin of cervical groove. 



Areola broad, length but slightly more than twice width, not de- 

 pressed. Cephalic portion of carapace more than two and one-half 

 times as long as areola. Punctations somewhat irregularly arranged, 

 about nine in narrowest portion. 



Rostrum long, broad, sides parallel at base, converging gently to the 

 lateral spines, which are opposite proximal part of second segment of 

 peduncle of antennule and which mark the base of the long, narrow 

 acumen. The distal end of the acumen opposite midlength of peduncle 

 of antennule. Postorbital ridges terminating anteriorly in acute 

 spines. 



Surface of carapace setose-punctate dorsall}^, and setose and finely 

 granulate laterally with a single strong lateral spine on each side. 

 Cephalolateral margins each with one well-developed spine immedi- 

 ately ventrad of anterior extremity of ceiwical groove, and a weak 

 tubercle on margin, slightly dorsad of base of antennae. 



Abdomen longer than cephalothorax and only slightly narrower. 

 Anterior section of telson wdth three and four spines in the right and 

 left posterolateral corners respectively. 



Epistome subtriangular in shape, heavily barbate, with margins 

 only slightly raised. 



Antennules of usual form; a strong spine present on ventral surface 

 of basal segment. 



Antennae extending to base of thii'd segment of abdomen. 



Antennal scale long, extending anteriorly beyond peduncle of an- 

 tennule and tip of rostrum, broadest proximal to middle. Lateral 

 margins concave, terminating distally in strong, acute spines. 



First right pereiopod slender and long, about four times as long as 

 broad. Fingers not gaping. Inner margin of palm almost 1.4 times 

 as long as broad, with a row of about 10 small, regularly spaced tuber- 

 cles. Entire palm setose-tuberculate, tubercles more crowded on 

 dorsal surface. No distinct ridges on either finger. Mesial margin of
