Subfamily LEPTOPODIIN/E. 



Eyes slender, not retractile, laterally projecting. Preocular and post- 

 ocular spines small or wanting. Basal joint of the antennae slender

Genus Podochela St. 



Carapace depressed, narrowly triangular, strongly produced in front. 

 Gastric region narrow, tumid, rostrum short, entire, triangular or arcuate. 

 Eyes long and laterally projecting. Basal autennal joint narrow, with a

 slender and visible from above. Merus of external maxillipeds much 

 shorter than the ischium, the apices obtuse or produced, the inner one

 very long. Chelipeds of moderate size; merus curved, the margins cili- 

 ated. Ambulatory legs very long, subprehensile, and often furnished with

Carapace pyriform; gastric region prominent, rounded, and bearing tufts 

 of curved setas; hepatic regions tumid, bearing two pointed tubercles, 

 the larger one above and in front of the smaller; cardiac region separated 

 by shallow grooves from the branchial and bearing a prominent elevation; 

 branchial regions flattened or tumid. Rostrum triangular, acute, and 

 bearing two double rows of curved setaa above; it varies considerably in 

 length, being sometimes broadly and sometimes narrowly triangular. 

 The area between the two projecting rims of the orbits is concave. There 

 is no tooth at the posterior margin of the orbit, but there may be a small 

 one a short distance behind it. Eye-stalks constricted at the middle and
