Stenopus scutellatus Eankin. 



Plate 29. 



Type : A male specimen taken under coral, near low water, Silver 

 Cay, Bahamas, and believed to be no longer extant. 



Distribution: Known from the Bahamas, where the ''Ara" speci- 

 mens establish the second record ; also from one female taken at Glover 

 Reef, Caribbean. 



Material examined : Two specimens, dredged in ten fathoms, Little 

 Stirrup Cay, Bahamas, February 28, 1925, by the ^^Ara." 



Technical description : Rostrum one and one-half times the length 

 of the precervical region, armed above with a row of about ten spines ; 

 no submedian spines present; midway the precervical region the 

 rostral row of spines is succeeded by a double row which thus con- 

 tinues almost to the posterior margin where it is replaced by a single 

 spine. The cervical groove is deep. The entire carapace is covered 

 with fine spines set in approximately longitudinal rows. The spines 

 are similar to those of 8. hispidus, but slenderer, and apparently 

 fewer and more delicate. The first two abdominal segments have the 

 spines arranged in two well separated, forward-pointing, transverse 

 rows, one each near the anterior and posterior margins of the respec-
