BULLETIN OF THE 



The first and second somites of the abdomen are broadly rounded above and 

 not at all compressed, but the succeeding somites are considerably compressed, 

 particularly near the dorsum, which is not really carinated on any of the 

 somite-s, however, though the third somite is prolonged in a very prominent 

 tooth over the' lourth. The first epimeron is brtjad and evenly rounded below, 

 the second much longer than high and elliptical, the third and fourth with tlie 

 posterior edges rounded, but the fifth produced posteriorly in an acute point. 

 The sixth somite is about twice as long as the fifth, less than half as high as 

 long, and very strongly compressed. 



The telson is about as long as the sixth somite, narrow distally, rounded 

 above, and armed with five to ten pairs of dorsal aculei and two pairs of long 

 spines at the tip. The outer lamella of the uropod reaches to about the tip ol 

 the telson, is nearly four times as long as broad, with the rounded tip extend- 

 ing much beyond the tooth in which the stout outer margin terminates and 

 just within which there is a spine as in most species of Fandalus. The inner 

 lamella is considerably shorter and much narrower than the outer, and lance- 

 olate in outline. 



In the female, the inner ramus of the appendage of the first somite of the 

 abdomen is lamellar, about two thirds as long as the outer, four times as long 

 as broad, and tapered to an acute point. In the male, this ramus is lamelliform, 

 but shorter and very much broader, being ovate and about twice as long as 

 broad. In the male the sexual appendage at the side of the stylet of the inner 

 ramus of the appendage of the second somite is as long as the stylet, and ex- 

 panded distally into a broad lamelliform and obtusely rounded tip. 



The surface of the carapax and abdomen is naked, but thickly punctate. 



All the specimens are imperfect and many of them fragmentary, and the 

 accompanying measurements are consequently very incomplete. 



The following measurements are in millimeters
