Bermuda 

 The first four series of measurements are by Prof. S. I. Smith. 



Ill No. 8316, the chelae are relatively much larger than in the 

 Bermuda example, probably owing to its maturity ; length of chela, 

 12.5 mm ; height, U.5 mm ; the nianns has a row of four conspicuous 

 denticles on upper edge, proximally : the edges of the digits are 

 strongly and coarsely toothed. The carpus has three conspicuous 

 distal tuberculiform teeth. The lateral teeth of the carapace are 

 conspicuous, the two anterior ones the larger and less acute; on tin- 

 left side the 2d tooth is double. The preorbital and suborbital teeth 

 are about as large as the lateral.
