CRUSTACEA FROM THE BAHAMAS 



has 12 segments ; united therefore for more than half its length. The 

 longer branch reaches beyond the undivided flagellum. 



Outer antennae : scaphocerite with lamellar portion slightly longer 

 than spinose, reaches beyond first ventral tooth of rostrum ; flagellum 

 exceeds the length of the body. 



Third pair maxillipedes reach to end of peduncle of inner antennae. 



First and second pereiopods : long, slender, and chelate ; second 

 longer than first ; chela in second as long as carpus. Third and fourth 

 pereiopods terminate in claws. 



Pleopods biramous, setose. Telson lanceolate, 4 mm. long, notice- 

 ably shorter than uropods, distal extremity with two sharp spines. 

 Outer uropod imperfectly divided transversely, the proximal division 

 ending in a lateral spine. 



This species is allied to L. petitinga F. Miiller, from Brazil (see 

 Ortmann, Revista do Museu Paulista, II, p. 191, 1897) and to L. 

 maculatus Thallwitz (Abh. Mus. Dresd., Ill, p. 19, 1891) from West 

 Africa.

 table, which exhibits the relationship :
