Diagnosis. — ^Carapace covered chiefly with a few large, spine-tipped 

 bosses or tubercles. One large hepatic spine. No tubercles on 

 basal antennal segment. Upper margin of manus of adult male 

 more than twice its width. 



Description. — The carapace bears 9 or 10 large, conical bosses or 

 tubercles covered except at the tip with very thick, short hair, 

 which makes them appear hemispherical with a smal^ shining point 

 emerging; besides there are a number of smaller, similar tubercles 

 symmetrically arranged. As in L. grandis, a row of curled hairs 

 extends from either side of the gastric region forward on to the rostral 

 horns. Rostrum moderately inclined. Only one hepatic spine, its 

 anterior margin sloping backward to the tip. No tubercle on the 

 margin of the supraocular eave or on the basal antennal article. 



Chelipeds of old male elongate, over twice as long as carapace; 

 merus with four spines above, two at the distal end and two near the
