 Florida (as S. quadridens Bigelow; Manning, 1959). Littoral, 



Material examined: 

 A14-39; 2 mi. S.W. of Cape la Vela, Colombia; April 8, 1939; 22 fms; 

 25? (one fragmented) (AHF). 



Measurements: Female, 26.2 mm, total length. 



Description: Eyes large, triangular, corneal and peduncular axes 

 subequal, cornea placed obliquely on stalk; rostral plate subtriangular ; 

 carapace without carinae except for reflected marginals and posterior 

 fourth of laterals ; raptorial dactylus armed with four teeth ; four 

 epipods present ; mandibular palp absent ; lateral process of fifth thoracic 

 somite an obtuse lobe, rounded laterally, vertical axis directed obliquely 

 forward ; lateral processes of sixth and seventh thoracic somites rounded 

 laterally, that of the seventh less convex and wider; submedian carinae 

 present on sixth abdominal somite only ; other abdominal carinae pres- 

 ent, spined as follows: submedian, 6; intermediate, 5-6; lateral, 5-6; 

 marginal, 5 ; telson with sharp crest ending in a posterior spine ; carinae 

 of submedian spines extending forward to base of crest; no other 

 carinae present dorsally on telson ; submedian spines with movable 

 tips ; prelateral lobes absent ; denticles 4-6, 8-9, 1 ; uropodal outer 

 branch with 6 movable, graded spines, the last extending to midpoint 

 of ultimate segment ; basal prolongation of uropods with 5-8 immovable 

 spines on inner margin of inner spine. 



Discussion: This species differs from S. quadridens in having long 

 submedian carinae on the telson and in lacking the short intermediate 

 carinae of the carapace. S. schmitti has but two dorsal carinae on the 

 telson, differing from S. tricarinata which has eight carinae in addition 

 to the two long submedians. 



A lima lebouri, described by Gurney (1946, p. 137, figs. 1-3) from 

 Bermuda, is probably this species, as the post-larval specimen reported 

 by him agrees in most respects with the present material. Gurney's 

 larva had but two epipods as opposed to the four found in the adult. 

 Because of the small number of epipods, Gurney felt that his material
