MARINE ZOOLOGY, 
Marine Zoology at Blackhall Rocks, Durham. — During 
the recent holidays, I took the opportunity of visiting Blackhall 
Rocks, on the Durham coast. Taking advantage of a low 
tide, I brought away several large Laminaria digitata which I 
uprooted. Encircling the stem, w T as abundance of that fine 
zoophyte Plumularia setacea. On the fronds there was Obelia 
geniculata in plenty, while near the root was the usual coat- 
ing of Membranipora pilosa. Among the roots I took a few 
worms ( Nereis diversicolor). One Common Brittle Star, 
Ophiothrix fragilis was also present. Two kinds of Crustacea 
were obtained from the Fucus. Hanging onto the Plumularia 
were numbers of Spectre Shrimps, Caprella linearis, and their 
movements over the zoophytes were most interesting. Several 
specimens of the spider-like Nymphon gracilis were taken 
among the roots of the Laminaria. 
The overhanging rocks yielded plenty of fine sponges, 
e.g., H alichondria panicea, mostly green or yellowish red, and 
the simpler calcisponge Grantia compressa. Alcyonium digi- 
tatum was abundant, and I noticed that the polyps did not fully 
expand except in a strong current of water. The sea anemones, 
Tcalia crassicornis and Actinia mesembryanthemum were 
common, but a fine colony of the large white Plumose Anemone 
Actinoloba plumosa, was a new sight to me. The rocks have 
few loose stones, but under most were quantities of Chiton 
cinereits. The commonest fish in the rock pools was Gunnellus 
vulgaris. — H. Preston, Middlesbrough. 
The Viking Society continues to issue its valuable Old-Lore Miscellany, 
the latest parts issued being Nos. 49 and 50 ; the last being the index 
number. The publication contains a fund of valuable information 
relating to the most interesting part of North Britain. 
Part 4 of the Transactions of the Yorkshire Numismatic Society (pp. 
87-110, A. Brown & Sons, 1/-), contains ‘ Treasure Trove found in Sheffield/ 
bv E. Howarth ; ‘ An Unpublished Leeds Penny Token of the Seven- 
teenth Century,’ by T. Sheppard; ‘Irish Regal Copper Coinage,’ by 
T. Pickersgill ; ‘ Coins in the York Museum ’ (illustrated by eight plates) 
by G. Benson ; ‘ Numismatic Notes,’ by the editor (Mr. Sheppard), and 
the Secretary’s Report and Financial Statement. 
From the Director of the Geological Survey we have received the 
Summary of Progress of the Survey for 1913, which contains a substantial 
account of the field work during the year, and also petrographical, chemi- 
cal, palaeontographical and photographic work of the survey, with a 
list of additions to the museum. In England and Wales the work of the 
Survey seems to have been principally centred round Bedfordshire, 
Warwickshire, Staffordshire, and London ; all this is carefully tabulated. 
There are three appendices, dealing with the Heswall boring ; a boring 
for coal at Hemington, Somerset ; and Additional Notes on the Geology 
of the Lothian Shale-field.
