Decapod Crustacea of Bermuda, Part II. 133 



subacute or slightly bidentate, outer convex surface, near tip, has 

 a slight lobe bearing a group of .hairs ; numerous other hairs are 

 at the tip and along the cutting edge. The carpus has a cluster 

 of hairs on the outer distal angle, part of them plumose, others are 

 long and plain. The merus also bears clusters of hairs on the 

 inner margin and on the outer distal margin. 



The smaller chela is more simple and not so much incurved ; its 

 fingers are narrower, more acute, and cross each other at the tips ; 

 its carpus is narrower, about as broad as long, not so cup-shaped. 

 The palm of the chela is ovate, but not so swollen as in the other 

 chela. Its fixed finger is similar, but more acute and scarcely 

 bidentate at the tip. The dactyl is narrower with a smaller and 

 narrower lobe on the cutting edge, and with only about three 

 apical denticles ; it has similar clusters of hairs. 



Legs of the second pair are very slender; carpus has three 

 unequal joints; middle one is longest, more than twice as long as 

 the third, and nearly as long as the chela. Third is shortest, 

 enlarged distally. The chelae are somewhat unequal in size and 

 form. The palm is longer than the fingers, which are incurved 

 and have tufts of hairs at the tips, which have two or three small 

 apical denticles ; their margins do not meet except at the tips and 

 have rows of hairs ; inner edge of dactyl has a small lobe. 



The three posterior pairs of legs are longer, slender, and sub- 

 equal; propodus and dactyl have a row of spines on the inner 

 edge ; dactyl is biunguiculate, or terminates in two incurved claws 

 or spines. The third and fourth legs are nearly alike ; the terminal 

 claws are moderately incurved and a little divergent; the inner 

 one is only about half as long as the outer; a few hairs stand 

 at their bases ; about four or. five minute appressed spinules are 

 on the inner incurved edge of the dactyl. The propodus has a 

 pair of spines at its distal inner angle, one on each side of the base 

 of the dactyl, and also a few longer stiff hairs ; along its inner 

 margin there is a row of about seven or eight spines, some of the 

 distal ones paired; proximal ones smaller; each spine is accom- 

 panied by a small stiff hair, a corresponding number of small 

 clusters of hairs also occur on the outer margin, sometimes as 

 many as eight. 



The fifth leg is similar to the fourth, but somewhat smaller. Its 

 dactyl is shorter and more incurved with about four appressed, 

 minute denticles on its inner edge; the terminal claws are shorter
