eathbun: decapod crustaceans. 315 



Sagami Bay, about 350 fathoms; Owston collection; 19- This specimen is 

 larger than any yet recorded : Length 153.5 mm., of which the carapace measures 

 58.5 mm.; length of large chela 108 mm., of small chela 53.5 mm. 



The anterior margin of the carapace outside of the rostrum is nearly trans- 

 verse ; this is not the case in Bate's figure, but is so in Willemoes-Suhm's figure 

 of the same specimen. The larger palm is more swollen in relation to the size of 

 the body ; its anterior half has about 8 small spiues above, 5 below, and a sub- 

 distal spiue on the inner side. The fingers move horizontally, the teeth of the 

 immovable finger slipping over those of the movable finger when closed; on 

 the proximal half, the spines of the two fingers form an angle with each other, 

 as shown in Doflein's figure.
