with a shallow notch near the distal end ; the inner margins 

 and the distal end of the outer margins are fringed with 

 moderately stout bristles. The inner plates, though also 

 moderately large, are smaller than the outer ones ; their 

 outline is subtriangular, with the distal end broad and evenly 

 but not very boldly rounded, and with a minute tooth-like 

 process near the outer angle ; the distal margin is also 

 densely fringed with fine hairs ; these inner plates are 

 situated one behind the other on the same side as shown in 

 the drawing (fig. 16, PI. III.), and it is interesting to notice 

 that Mr. Stebbing, in the work referred to above, shows these 

 plates arranged in the same way as described here, which 

 therefore probably is the normal position of them in this 

 species — a position that does not seem to be usual among the 

 Amphipoda. 



The first and second gnathopoda are nearly alike, and 

 they are both unprovided with chelae. The end-joint bears 

 three apical spines, the middle one being twice or three times 

 longer than that on either side (tigs. 13 & 14, PI. II.). 



In the fifth pair of thoracic legs (the third pair if the 

 gnathopods are not counted) the basal joint is not armed with 

 marginal teeth as in Scina, nor is the distal end produced 

 into a spiniform process. 



The third pair of uropods are moderately stout ; the inner 

 branch is about as long as the basal joint, the outer margin 

 of this branch and the inner margin of the outer branch are 

 both finely serrated. Telson small, subovate. 



Parascina fowleri has also been recorded by Chevreux 

 and Tattersall. Its occurrence at ( Goldseeker ' Station 53 

 extends its distribution northwards considerably. 



Genus CYSTOSOMA, Guerin-Meneville. 

 Cystosoma spinosum (Fabr.). 



A small specimen of Cystosoma scarcely 20 mm. in length 

 was obtained in a gathering collected by the c Goldseeker ' in 

 August 1907 at a depth of a little over 500 metres in lat. 

 60° 31' N., long. 3° 53' W., that is in the Faroe-Shetland 

 Channel, but nearer Shetland than Faroe. A slight dorsal 

 ridge extends from the cephalon to the base of the telson. 

 Each segment has the posterior margin denticulate; the 

 median dorsal tooth is of moderate size, but the other denticles 

 are small, and they are more numerous on the margins of the 

 pereion-segments. The specimen is devoid of colour and 

 almost transparent. Tattersall records this species from
