1244 THE VOYAGE OF H.M.S. CHALLENGER. 



to the preceding pair, but rather stronger, the fifth joint longer ; the little prominence 

 on the front margin near the base of the fourth joint is rather more marked in the 

 fourth and fifth than in the third perseopods. 



Uropods. — The longer first pair are two-jointed, the first joint short, with a group 

 of slender spines standing stiffly out from the outer distal angle, 'and a short spine at 

 the inner distal angle ; the second joint long, slender, somewhat curved, pectinate with 

 small teeth at right angles to the concave inner margin, the convex outer margin having 

 some spinules near the centre ; the corner of the pleon just above the uropods has a 

 group of slender spines ; the much shorter second uropods are perhaps one-jointed ; the 

 terminal joint, whether solitary or not, is tapering, a little curved, smooth. 



Length. — In the position figured, the specimen measured from head to pleon two- 

 fifths of an inch. 



Locality. — Station 149e. off Greenland Harbour, Kerguelen Island, January 21, 

 1874 ; depth, 30 fathoms; bottom, volcanic mud. Two specimens, males (one mounted 

 in Canada balsam).

1 Mayer, Caprelliden, p. 196, gives the reference as follows : — " Grube, A. E., Ueber die hohere Crustaceenfauna 

 des Mittelmeeres, Naturhist. Section der Schlesischen Gesellschaft. Sitznng am 1. April 1863. (Mir nur aus einem 

 unpaginirten Sonderabdrucke bekannt geworden)." He refers to it for the species CapreUa quadrispinis, Grube, which is 

 in Mayer's opinion a synonym of Protella phasma, Montagu. I have not seen this paper of Grube's either paged or 

 unpaged.
