j udging from the last leg, in which alone these parts remained, 

 are thin and small, with a few spines on the anterior margin, the 

 finger thin and curved, with a small hair at the root of the nail. 



The first three pleon-segments are rather longer than the 

 segments of the pereion. The first uropods have the peduncle 

 long, and the branches about the same length as the peduncle. 

 In the second uropods the peduncle is a good deal shorter, 

 with branches to correspond ; in the third the peduncle, Avhich 

 has minute close-set hairs on its upper edge, is as long as in 

 the first, but the branches are shorter than in either of the other 

 pairs. The telson is triangular, elongate, slightly concave 

 above. There is a minute angle on either side, just before 

 the sharp apex is reached. 



The solitary specimen obtained was dredged off Tenby in 

 a few fathoms depth. Its length is a twelfth of an inch. 



Amphilochus concinna. 

 ( CaUimefus acudiffitata.) 



Dredging at Tenby having yielded me three specimens of 

 Amphilochus concinna of various sizes and in more or less 

 good condition, a careful examination of them enables me to 

 add some details as to the structure of this species. The 

 flagellum of the lower antennae varies from three to five arti- 

 culations. In the smallest specimen the tooth-like process, 

 which in the others is so conspicuous a terminatioii to the 

 upper margin of the hand in each gnathopod, is scarcely at all 

 developed ; the palm is fringed with a row of short, very fine 

 and even hairs, but without perceptible denticulation ; the 

 long produced process of the wrist in the second gnathopods 

 ends in two short cilia, being otherwise quite smooth. In 

 the larger specimens, however, this process ends in three 

 good-sized cilia, besides having two or three on each of its 

 lateral margins. The shorter process of the first gnathopods 

 has several cilia at and about the distal end. In the hands of 

 both gnathopods the palms are not only denticulate, but have 

 a short fine hair in each denticulation ; while the fingers, in- 

 stead of having the inner margins smooth as in the female 

 previously described (^ Annals,' Dec 1876), have them fringed 

 with fine hairs, the row terminating at the base of the nail in 

 a small but well-marked spine-like process. 



The telson is lanceolate and boat-shaped. In all three 

 specimens the last uropods were unfortunately missing j but 

 the character of these may, I think, be safely taken from the 

 description and figure of Callimerus acudigitata^ given in this 

 Magazine for December 1876, and again referred to in the 

 number for January 1878. What in establishing that genus
