18 ALLAN HANCOCK ATLANTIC EXPEDITION REPORT 



was distinct from S. quadridens, of which a post-larval specimen was 

 figured by Bigelow (1894, p. 547, fig. 27) who showed five epipods; 

 Bigelow's figure may be in error, as the adult has but four epipods. 

 However, two post-larval specimens of S. quadridens in the U. S. Na- 

 tional Museum have only two epipods; the specimens are 11.9 mm 

 (USNM 21482) and 12.4 mm (USNM 21483) in total length. A third 

 specimen (USNM 96403) 14.2 mm in total length, has the full comple- 

 ment of four epipods. Gurney's post-larvae measured 12-14 mm in total 

 length, so it is possible that the remainder of the epipods would be 

 added during subsequent molts. 



It is also possible that J. lebouri is the post-larva of S. tricarinata, 

 which also has four epipods and long submedian carinae on the telson. 

 Although the adult S. tricarinata has 8 supplementary carinae on the 

 dorsal surface of the telson, Schmitt (1940, p. 162) pointed out that 

 juveniles of S. hancocki did not possess additional carinae on the telson, 

 although this was a characteristic feature of the adults. For this reason, 

 A. lebouri cannot be assigned to either species until more of the inter- 

 mediate larval stages are known. 



Although Lemos de Castro (1955, p. 10) could find no traces of] 

 movable tips on the submedian teeth of the telson, the tips are clearly] 

 movable in the present material. 



Remarks: The present material shows no distinctive color pattern.] 



This species had not been reported outside of Brazil; the Colombia 

 and Florida material extends the range considerably to the north and] 

 west.
