ON THE DREDGING OF THE NORTHUMBERLAND COAST. 119 
appendages, armed with a spine on each side and eight spines around the 
extremity. Deep water off Tynemouth. 
“ Cyrianassa ciliata (Norman, Nn. sp.). 
“ Carapace hispid, truncate in front, and furnished with a toothed process on 
the antero-lateral margin. Lower antenne longer than the body. Five seg- 
ments of the thorax uncovered by the carapace. Abdominal legs, two pairs, 
attached to the first two segments. Telson short, one-third the length of 
the basal joint of the lateral appendages, with a rounded unarmed extremity. 
Caudal appendages furnished with plumose cilia, which are remarkably long 
on the outer branch. Deep water off Tynemouth.” 
Among the more interesting Amphipoda obtained were Montagua Alderii 
and pollexiana, Callisoma crenata, Anonyx denticulatus, Anvpelisca Gaimardi 
and Belliana, Phoxus plumosus, Iphimedia obesa, Acanthonotus testudo, Atylus 
bispinosus, Microdeutopus anomalus, Caprella lobata, Dewamine Vedlomensis, 
Kroyera altamarina, and Melita prowvma. Of the last three species only the 
type specimens were previously known. 
Two Entomostraca were dredged which are new to the British fauna, 
Cypridina globosa (Liljeborg) and Ichthyophorba hamata (Liljeborg), and a 
third, new to science, thus described by Mr. Norman :— 
*« Oythere limicola (Norman, 0. sp.). 
* Carapace-valves slightly quadrilateral, front margins oblique, greatest 
height at the anterior third. Sculptured with two elevated, longitudinal, slightly 
curved parallel lines on the lower half of the valves, from the anterior 
extremity of which a transverse elevated line passes to the hinge-margin, 
where it terminates in a large tubercle. Two similar tubercles close together 
near the hinder extremity of the hinge-margin.” 
Among the other Entomostraca were Nebalia bipes, Cythere quadridentata 
and acuta, and what is perhaps a variety of flavida, Cythereis fimbriata, 
Evadne Nordmanni, and Anomalocera Patersonit. 
Of Pycnogonoidea (which we only separate from the Crustacea because 
they have been on this occasion examined by different gentlemen, and not 
as expressing an opinion that they should be so separated) ten species were 
obtained, belonging to four genera, Pycnogonum, Phowichilidium, Pallene, and 
Nymphon. Of these, two are new to Britain and two are new to science ; 
the latter are thus described by Mr. George Hodge :— 
“ Pallene attenuata, n. sp., Hodge. 
“Rostrum thick, constricted at the base, swollen near the middle, and 
rounded at the apex. Legs long, sparingly hispid; first, second, and third 
joints short, the second the longer; fourth rather stout, and as long as the 
second and third united; fifth and sixth slender, and about the length of the 
fourth ; seventh very short ; eighth convex on the outer margin, straight on 
the inner, with a few short hairs scattered along both margins. A single 
claw at the extremity, which, when pressed against the limb, reaches to the 
junction of the seventh joint. Foot-jaws long and slender, projecting con- 
siderably beyond the end of the rostrum. Anterior portion of thorax 
attenuated, and advanced nearly in a line with the tip of the rostrum, where 
it slightly bulges and gives origin to foot-jaws, immediately behind which 
is seated the oculiferous tubercle, which is long and narrow. Abdomen long, 
rounded at apex, slightly tapering to base. At the origin of each leg on the 
dorsal aspect is a large wart-like protuberance. 
*« Nymphon brevirostris, n. sp., Hodge. 
“Rostrum short and stout ; foot-jaws thick, divergent, second joint or hand 
nearly as long as the first; palpi five-jointed, brush-like, first and second
