Diagnosis. — Rostrum with lateral spines; areola moderately broad 

 with four or five punctations in narrowest part; cephalothorax 

 granulate laterally, punctate dorsally ; a single lateral spine present on 

 each side of carapace. Male with hooks on ischiopodites of third 

 and fourth pereiopods ; palm of chela of first-form male not bearded 

 but bearing a row of seven to nine tubercles on inner margin; post- 

 orbital ridges terminating cephalad in spines. First pleoj)od of first- 

 form male with no marked hump on cephalic surface but with a 

 noticeable "knob" on lateral surface opposite the caudal process; 

 tip terminates in four distinct parts (of which all except caudal proc- 

 ess are directed caudad at approximately a right angle to main shaft 

 of appendage) : mesial process long, slender, subcylindrical, non- 

 corneous, lies considerably proximad of and extends much farther 

 caudad than the other terminal elements ; cephalic process moderately 

 short, compressed, corneous, and somewhat hoods the more prominent 

 central projection; caudal process slender, somewhat flattened, 

 corneous, lies proximad of the central projection, and is directed at 

 about a 45° angle to the main shaft of the appendage; central projec- 

 tion compressed, corneous, beaklike, and extends slightly farther 

 caudad than either cephalic or caudal processes. Annulus ventralis 

 as in fig. 81, d^ decidedly broader than long with a prominent raised 

 area on cephalolateral (dextral or sinistral) side of sinus; sternum 

 immediately cephalad of annulus with multituberculate prominences 

 which extend caudad to cover a portion of annulus.
