The only specimen taken (a male) has the following measure- 

 ments — 

 Length of carapace from tip of rostrum to first abdominal segment... 9 mm. 



Length of chelipecle 13 ,, 



Length of first ambulatory leg 25 ,, 



Length of fourth ambulatory leg 17 ,, 



This species is readily distinguished from the type-species, L. 

 bispinosa Henderson, by the spinules of the carapace and on the 

 merus of the ambulatory legs. L. bispinosa was taken by the 

 " Challenger " in 95 fathoms off Zebu, Philippine Islands. It is 

 also recorded by Alcock* from 53 fathoms in the Andaman Sea.

Anterior region of the carapace rugose with a well defined 

 margin, the rostrum reaching very slightly beyond the marginal 

 teeth. The lateral margin is armed with three or four obscure 

 spinulations and with scattered hairs. The posterior and little 

 calcified wings of the carapace also carry scattered setse. 



The ocular scales carry an acute tooth on their inner margin 

 and are separated by a considerable interval. 



The ocular peduncles are slender, slightly thicker at the base 

 than at the summit and somewhat constricted in the middle. 

 Their upper surfaces carry scattered hairs in their proximal half. 



The first exposed joint of the outer antennae is without any 

 spine. The succeeding joint carries two spines on its outer 

 margin near the distal end and one on its inner distal extremity.
