Nicippe tumida, Bruzelius, Skandinaviens Amphipoda Ganimaridea (1859), 

 p. 99, pi. 4. fig. 19 ', Bate, Cat. Amphip. Britisli Museum, p. 374. 



Superior antennae with, very short peduncle, not longer than 

 the head, first two joints subequal, last joint not half the length 

 of the preceding ; flagellum long and slender, first joint long, 

 following joints wider than long ; appendage five-jointed. In- 

 ferior antennae much shorter than the superior, but the peduncle 

 considerably longer. Onathopods of similar structure ; wrist 

 short, triangular ; hand regularly ovate, palm undefined, finger 

 slender, only very slightly curved, as long as the hand. Pe- 

 reiopods with peculiarly long, perfectly simple, straight nails ; 

 last pair long and slender, thigh narrow, furnished with a most 

 remarkable appendage on the middle of the posterior margin 

 (which is not expanded) ; this appendage consists of a very 

 long styliform process, the distal portion of which is a plume 

 formed of hairs springing from all sides of the axis. Pleon 

 with two small teeth on the posterior dorsal margin of the 

 fourth segment. Telson squamiform, divided almost to the 

 base, and consisting of two long, narrow, diverging portions, 

 furnished with three or four lateral and two terminal long 

 slender spines. Uropods : first pair rather longer than second, 

 both margined with numerous very long slender spines ; last 

 pair having on the basal portion a tuft of long slender spines ; 

 rami subequal, long, narrowly 1-anceolate, fringed with very 

 long plumose setae. Length not quite half an inch. 



Two specimens, taken by Mr. Jefireys and myself, in July 

 1866, in the Sound of Skye. Mr. Bate, in his ^ Catalogue of the 

 Amphipodous Crustacea in the British Museum ' (p. 374), 

 states that he had seen a specimen from Shetland ; but possibly 

 there may have been some mistake in this, as the species is 

 not included in the ^ British Sessile-eyed Crustacea.' 



The short peduncle of the upper antennae, the ovate gnatho- 

 pods, and, above all, the extraordinary styliform appendage of 

 the thigh of the last pereiopods at once suffice to distinguish 

 this species. What the use of the last-mentioned organ is 

 I can form no idea ; the nearest approach to it in structure 

 that I know among the Crustacea is to be found in the abdo- 

 minal setae of the Cladocera. 



Genus Eriopis, Bruzelius. 



Body elongated, slightly compressed ; coxae small. Superior 

 antennce with a slender peduncle and a very minute secondary 

 appendage. Inferior antennae subpediform. Mandibles two-
