CEUSTACEA OF PRANZ-JOSEP LAND. 101 



bears a one-jointed branch which is subapical (fig. 21). A 

 moderately long plumose seta springs from the basal joint of 

 the palp a short distance below the one-jointed branch. The 

 posterior foot-jaws are moderately stout, and are each f urcislied 

 with an elongate and slender terminal claw. The first pair of 

 swimming-feet somewhat resemble those of Dactylopus longi- 

 rostrls, Claus, but are rather more slender (fig. 22) ; a small 

 seta springs from about the middle of the inner margin of the 

 first joint of the inner branches, while the outer margin is 

 f ringed with minute hairs ; the inner branches are also armed 

 v.ith a moderately stout terminal spine and an elongate slender 

 seta ; the outer branches, which are rather more than half the 

 length of the inner, are composed of three subequal joints. The 

 inner branches of the second, third, and fourth pairs are 

 two-jointed ; in the fourth pair (fig. 23) the two-jointed inner 

 branches are short, but the outer, which are three-jointed, are 

 elongate. The fifth pair (fig. 24) are somewhat similar to those 

 of Dactylopus minutus, Claus. The caudal furca are very 

 short. 



Memarhs. This species resembles very closely one of the smaller 

 species of Dactylopus both in its general outline and in its six- 

 jointed antennules ; but it is precluded from that genus by the 

 structure of the mandible-palp and by the inner branches of 

 the second, third, and fourth pairs of swimming-feet being only 

 two-jointed, and in these respects it agrees more closely with 

 Ganthocamptus than with any other described genus. In the 

 original description of the species, reference is made to one or 

 two points in which the species does not agree with Cantho- 

 camptus, and which may by-and-by render its removal from that 

 genus necessary. I am inclined, however, for the present to 

 leave it as described. The length of the specimen figured 

 (fig. 18) is -48 mm. (Jg of an inch). The Firth of Forth is the 

 only British habitat of the species known to me.

This well-marked form was dredged off East Glacier in 

 30 fathoms, and also ofi:" "West Point in 2 to 3 fathoms ; both 

 localities being in the vicinity of Cape Flora, Northbrook Island. 

 It was dredged at West Point on June 4th and on July 2nd and
