This is evidently closely allied to 6". minus and may, perhaps, 

 prove to be the same. It has three small, short, equal, triangular 

 frontal teeth ; the antennular spine reaches the middle of the 

 second segment ; the basal antennal spine is stout and its tip is 

 about even with that of the antennular spine. The spine of the 

 scaphocerite is narrow and acute. The larger chela has the palm 

 about twice as long as the dactyl ; the distal articular margin is 

 nearly transverse and has several small denticles. The principal 

 differences noticeable in the figures are in the form of the antennal 

 spines and the shorter large chela, with a more transverse articular 

 margin. 



Dana did not describe nor figure the uropods and telson. It is 

 impossible to determine with certainty its relation to the species 

 now recognized. It was from Rio Janeiro, Brazil. 



S. saulcyi Guerin, from Cuba, seems to be the true 5\ minus of 

 Coutiere. See PI. XXV, fig. 3, and PI. XXXI, fig. 4, copied from 

 Guerin's figures. Some of our Bermuda specimens agree well 

 with Guerin's figures in all essential respects, but his general figure 

 is incorrect in certain parts. It does not even show articulations 

 in the carpus of the second pair of legs. 



Four small but perfect specimens (No. 1174) collected at Key 

 West by Edw. Palmer, and now in the Yale Museum, were 

 labelled as minus by Prof. Kingsley. Some are females, with 

 large eggs. The rostrum is minute and acute ; the ocular lobes 

 have small acute spinules. The telson is very narrow, tapering 

 rapidly distally. The large chela has a conical, acute, distal, dorsal 

 spinule turned upward ; small chela is short, attached low down. 

 It appears to be the S\ brooksii Coutiere.
