118 GAMMARIDJI. 



and distal extremity furnished with hairs those upon the 

 latter position are very long, and split at the extremity 

 into two branches ; the hand is long and narrow, having 

 the margins parallel and the apex truncate ; the anterior 

 half is furred with short hairs, a few long and large ones 

 are also attached to the upper margin and apex; the finger 

 is attached near the centre, so that the palm consists of 

 but half the apical margin ; its outline is waved, and the 

 short finger is tuberculated upon the inner margin. The 

 first two pairs of walking legs are uniform and tolerably 

 robust ; the last three are equally so, but they have the 

 second joint developed into an oval scale, which extends 

 downwards as far as the extremity of the joint next suc- 

 ceeding. The caudal appendages have their branches 

 subequal, the penultimate pair are shorter than the pre- 

 ceding or ultimate. The terminal branches are furnished 

 with short spines upon the upper and inner margins, 

 those of the penultimate have the extremity of the inner 

 branch subapically furnished with a long spine, which 

 gives this branch the appearance of terminating in a 

 double extremity. The central tail-piece is divided to 

 about two-thirds of its length; the outer and upper 

 margin of each division is supplied with three equi- 

 distant spinules, two or three more of which cover the 

 apex of each half. These spinules or small hairs are 

 subapically furnished with a branch still more minute. 



We have received specimens of this species from the 

 Moray Frith, collected by the Rev. Mr. Gordon, of 

 Elgin, and Mr. Edward, of Banff. From them our 

 figure and description are taken. On a comparison with 

 the figure given by Kroyer, our specimens appear to be 

 comparatively longer, but in all other respects their 

 identity appears to be complete.
