Diagnosis. — Carapace with 6 median spines. Three dorsal spines and 

 tubercles on branchial region; no dorsal spine on hepatic region. 

 Spines uneven; 8 are long, forming a cross. 



Description of young specimen. — -Carapace pyriform, much longer 

 than wide, exchiding spines. Six median spines, 2 gastric, 1 genital, 

 2 cardiac, 1 intestinal; the anterior gastric and the genital spine are 

 very small, the others long. Marginal spines 5 (paired), the posterior 

 one very long, the others small. Dorsal branchial protuberances 3, 

 forming a triangle, the posterior one very long and forming a con- 

 spicuous line of 5 with the anterior cardiac spine and the postero- 

 lateral spine; the innermost of the branchial triangle is a low spine, 

 the outermost a small tubercle. Rostrum very long, bifid for half 

 its length, horns slender, moderately divergent, tips sharp-pointed 

 and subparallel. Two pterygostomian spines, in a longitudinal line, 

 the anterior one the larger. A tooth at the antero-lateral angle of the 

 basal segment of the antenna and one on its outer margin. 



Chelipeds of the immature specimens examined weak and shorter
