38 KEV. T. R. E. STEBBING ON AMPHTPODA FEOM 



Telson. This is a little longer than broad. The broadly rounded apex does not reacli so 

 far back as the projecting points of the preceding segment, which are in turn overlapped 

 by the peduncles of the second uropods and these by the peduncles of the first pair. 



The length of one specimen, with tail folded in, was less than a tenth of aa inch, of the 

 other rather more than a tenth. 



Hab. West Indies. From Goniastrcea varia Dana. 



The name is given in compliment to my friend, Dr. H. J. Hansen, the accomplished

Pirst antennae longer than second, second joint of the peduncle longer than the first, 

 both flagella many-jointed. Mandibles with broad cutting-edge ; tliat on the left side 

 having two blunt teeth above and two that are acute below, one of them small, the other 

 large, a rather broad accessory plate with crenulate edge, and two plumose spines ; that 

 on the right having a similar cutting-edge miuus the smaller acute tooth, no accessory 

 plate, but three plumose spines ; the three-jointed palp slender, fringed with setiform 

 spines. Pirst maxillte with one seta on the small inner plate, seven very unequal spines 

 on the inner plate, one of them plumose; the second joint of the j^alj) broad, with many 

 spinules about the apical margin. Second maxilbne with the plates slender, the outer 

 carrying three, the inner seven sctse. Maxillipeds with inner plates vei-y small, outer 

 plates short and narrow, fringed with spinules, the supporting joint not very large; j^alp 

 with first joint short, second robust and long, but scarcely longer than the third, the 

 finger long and slender with minute setules on the inner margin. Tlio tritiu-ating 

 organs (anterior lateral gastric lobes) are armed with six long spines. The gnathopods are 

 similar, simple, with the fifth joint robust, fusiform, the sixth and seventh slender, the 

 seventh fringed with minute setules. The peraiopods are slender, elongate. The second 

 uropods have the rami unequal, the third have the rami foliaceous. The telson is 

 deeply cleft.

Head with acute rostrum. There appears to be a small dorsal denticle on each of the 

 last two or three segments of the pleon. 



First antenncB. The first joint stout, the third half the length of the second ; of the 

 flagellum thirteen joints remain, the first much the longest ; of the accessory flagellum 

 seven or eight joints remain, the first as long as that of the primary. 



Second antennce. Last tAvo joints of the peduncle elongate, the last shorter than the
