120 REPORT—1862. 
joints long and nearly of the same length, either of them equal to the three 
terminal joints, the last of which is the shortest. Thorax robust. Abdomen 
stout and conical. Oculiferous tubercle midway between the first pair of 
legs. Legs stout, sparingly furnished with stout spine-like hairs; first and 
third joints short ; second slender at its origin, swelling upwards; fourth and 
fifth joints each as long as the first three; sixth much longer, and slender ; 
seventh short; cighth long, slightly bent, furnished along its inner margin 
with a few short spines, and terminating in one moderately large and two 
small claws.” 
Two species of Nymphon new to Britain were also taken, viz. Nymphon 
hirtum, O. Fabr., and NV. brevitarse, Kroyer, 
The rarity of male Nymphons is singular; none were obtained during the 
expedition, although the number of females was considerable : on the contrary, 
the males of Pycnogonum were abundant, and the females rarely seen. This 
seems to be the usual experience of collectors. 
The researches of Mr. Hodge into the development and structure of the 
Pycnogonide have led him to place them with the Entomostraca, as an order 
of that subclass, Arachnopoda or Pycnogonoidea. 
A great number of Annelids were dredged, but these have not yet been 
catalogued ; we trust, however, next year to present a satisfactory list of these 
animals. Sipunculus Bernhardus was one of the most abundant species, occu- 
pying every dead Dentalium which was brought up. It may be remarked also 
that in the deepest water dredged, that is, off Berwick, the dredge showed the 
bottom to consist almost entirely of fragments of the deserted tubes of these 
creatures. Few opportunities existed of obtaining Entozoa; those that did 
occur were not neglected, but the number was so meagre that no list has been 
attempted. 
Of Echinodermata we dredged twenty-seven species; amongst these is one 
species of Ophiura hitherto undescribed, of which Mr. G. Hodge, who had 
a short time before taken it on the Durham coast, gives the following 
description :— 
“ Ophiura Normani (n. sp., George Hodge). 
“Disk either pentangular or round, the former pertaining to well-grown, 
the latter to young specimens. Upper surface of disk rotulated, under 
surface corresponding with that of the other members of the genus. Two 
clasping scales at the origin of each ray, each bearing about ten short spines. 
A crescent of eight or ten short blunt spines on the upper surface of the rays, 
close to the disk. Lateral ray-plates bearing five moderately long spines. 
Upper ray-scales nearly square, slightly tapering towards the disk. [ays 
about four times as long as the diameter of the disk, which in well-grown 
individuals measures about 3 of an inch. Colour reddish yellow, occasionally 
of a pale sandy tint.” 
The Rey. A. M. Norman has also taken a single specimen of this species in 
the Clyde, and three or four in the Shetlands. 
Bryssus lyrifer, a species previously considered to be of much rarity on the 
coast, was met with in great plenty and of unusual size; still more abundant 
were Spatangus purpureus and Amphidotus roseus. 
All the species of Ophiuroidea, Asteroidea, and Echinoidea were much 
more plentiful on the muddy ground which lies immediately within the 
Dogger Bank than elsewhere. 
Uraster rosea, a fine species not before met with on the east coast, was 
added to the local fauna. 
Among the Holothuride, several specimens of a small Thyonidium were
