420 REPORT—1896. 
margin with five or six teeth on the anterior half increasing in size an- 
teriorly, forming a right angle with the anterior margin which has five 
teeth just below the rostrum, the second from the rostrum being the 
largest ; rostrum horizontal, blunt, about one-sixth the length of the cara- 
pace, with five small teeth on the lower margin. 
First pair of legs with seven teeth on the lower margin of the first 
joint.. Second pair with a large spine at the distal end of the second, 
and two unequally long spines at the end of the third joint. Third pair 
with an appendage on the second joint, consisting of two parallel curved 
blades, twice as long as the succeeding three joints. Length 8} mm. 
The above interesting species has a general resemblance to Lewcon, 
from which genus, however, it may be at once distinguished by the ap- 
pendages on the fourth pair of legs in the female and the third pair in the 
male. It was taken in the tow net attached to the back of the trawl 
net on April 22, 12 m. S.W. of Chicken Rock, 33 fathoms. 
Eudorella emarginata (Kréyer).—One female. Same locality as last. 
Campylaspis glabra, G. O. Sars.—Three specimens, from same locality 
as last. A Mediterranean species, not previously recorded from British 
Seas. I have specimens taken by Mr. Ascroft off the Ile d’Yeu. 
AmpPHIPoDA :—WNormanion quadrimanus (Bate and Westwood).—One 
small specimen ; length 2 mm., 6 miles W.S.W. of Calf, 23 fathoms. 
Stenothoé crassicornis, n. sp.—Three males. Same locality as last. 
Mandibles without a palp. 
Maxillipedes with the basal lobe very small, divided to its base. 
Antenne stout, the flagellum of the lower but little longer than the 
last joint of the peduncle ; its first joint almost as long as the remaining 
four together. 
First gnathopods as in S. marina. 
Second gnathopods with the palm of the propodos defined near the 
base by a triangular tooth, the distal extremity expanded and cut into 
four blunt lobes, of which the proximal is much the largest ; dactylus 
with a prominence on the inner margin, coinciding with the palmar lobus. 
Perzopods short and strong, the third (meros) joint in the last three 
pairs much produced backwards, as in Proboliwm calearatum, G. O. Sars. 
Third uropods with four spines on the upper surface of the peduncle, 
which is twice as long as the first joint of the ramus. 
Telson with three pairs of dorsal spines on its proximal half, the first 
pair the smallest. Length 2 mm. 
In the form of the hand of the second gnathopods this species ap- 
proaches S. tenella, G. O. S., and S. Dollfusi, Chevreux ; but both these 
(perhaps identical) species are remarkable for the length and slenderness 
of their antennz and perzeopods. 
Halimedon parvimanus, Sp. Bate.—Five or six specimens, 12 m. S.W. 
of Chicken Rock, 33 fathoms. 
Argissa hamatipes (Norman) =Syrrhoé hamatipes, Norman, ‘ Brit. Ass. 
Rep.,’ 1868 (1869), p. 279. 
Same locality as last.—Two females, one with ova, 2 mm. long. 
Prof. G. O. Sars, with some hesitation, follows Boeck in placing Argissa 
among the Pontoporeiidz, but there can be little doubt that Canon A. M. 
Norman was right in classing it with the Syrrhoide. 
Gammarus campylops, Leach,—Brackish pond near Colwyn Bay ; also 
Port Erin harbour.
