part deeply incised, but with any brush. (First antennular joint at 

 most reaching the front margin of the eyes and generally distinctly 



shorter) L. intermedius n. sp. 



l>. Terminal portion of the petasma has the end distinctly expanded as 

 a kind of oblique plate, the distal part has no transverse lines and 

 no protruding plates, but its convex proximal side is scabrous from 

 small, transverse, sharp knots. Proc. ventralis is a moderately slender 

 plate terminating in a more or less distinctly bipartite brush. (First 

 antennular joint reaches at most slightly beyond the front margin 

 of the eyes, and is generally a little shorter, not reaching to that 



maro-in) '. . . . L. penicillifer n. sp. 



c. Terminal portion of the petasma with the end acute, and no trans- 

 verse lines or protruding plates or scabrousness. Proc. ventralis is a 

 slender needie with acute end. 



a. Exopod of uropods with the marginal process reaching beyond 

 the upper terminal angle. (First antennular joint overreaches 



conspicuously the eyes) L. Faxonii Borrad. 



8. Exopod of uropods with the dentiform marginal process termi- 

 nating conspicuously and generally far before the upper terminal 

 angle. (First antennular joint about as long as or a little longer 

 than the eyes) L. Hanseni Nobili. 



K e y t o the Females. 



a. Exopod of uropods from somewhat more than four to a little less 

 than five times as long as broad; the marginal spine terminates only 

 somewhat or a little before the distal upper angle or even beyond 

 that angle. 



a. First antennular joint reaches at most a little and most frequently 



not beyond the eyes L. intermedius n. sp., and L. penicillifer n. sp. 



8. First antennular joint reaches considerably beyond the eyes . L. Faxonii Borrad. 



b. Exopod of uropods somewhat broad, only about four times as long 

 as broad; its marginal tooth terminates very considerably before the 



distal upper angle * L. Hanseni Nobili.
