NATUEAL HISTOEY NOTES IN DEYON AND COENWALL. 
During a hurried visit paid to CornwaP and South Devon, a few inter” 
esting facts came under my notice, which I would wish to place on re¬ 
cord in the Proceedings of the Association, as hearing on a subject 
which at present is assuming some importance among naturalists, viz., 
the distribution of the lower forms of animal life in the British isles. 
The greater part of the observations were made in company with C. 
Spence Bate, P. L. S., to whose kindness I am indebted for the identi¬ 
fication of most of the amphipodous Crustacea noticed, and most of which 
were obtained in a dredging excursion in company with him and Dr. 
Hugh Palconer, the Pev. Mr. Everest, and Dr. Dansey, in the harbour 
and roads of Plymouth, within the Breakwater, on the 22nd of April last. 
The results afforded deserve to be noted, as the ground is similar in 
its nature to the ground over which most of my Dublin work has been 
done, and, therefore, allowing of a comparison being drawn between 
these two localities. 
The nature of the grounds over which we dredged were as follows:— 
1. Muddy black sand: here we obtained Gebia deltura (one specimen). 
Ophiocoma bellis, Comatula rosacea, and a few other species. 
2. Shingle free from mud or sand; from hence the more remarkable 
species were— Bernhardus Hyndmanni , B. Thompsoni, B. Icevis, B. Cua- 
nensis, Bernhardus streblonyx, —all, however, except the last, much rarer 
than in similar grounds in Dublin. Inachus Borsettensis , tolerably com¬ 
mon ; Eyas coa/rctatus , one specimen; Eurynome aspera, common; 
Pilumnus hirtellus, common. Portunus puber and P. depurator, common. 
P. holsatus, one specimen. Porcellana platycheles , one specimen. P. 
longicornis , very common. Galathea Andrewsii, common, but rarer than 
in Dublin. 
3. A Zostera bank, called by the boatmen the “ Leek Bank.” Here, 
in addition to B. streblonyx, Port, depurator and puber, single specimens 
of Galathea squamifera, Crangon vulgaris, and Hippolyte (Lysippe) Gran- 
chii, occurred; and the only Isopod met during the day, Idotea pelagica. 
We took but one cast of the dredge here. 
4. Pidges of slate, which were perpetually bringing up the dredge, 
required a long and strong pull to free it. Among these, in addition to 
Echinidse, we met an old bone containing, safely ensconced within it, 
a female Portunus arcuatus in spawn. It was impossible to note the 
localities of the Amphipoda obtained, further than that they were more 
numerous than in Dublin Bay. 
The following were among the rarities obtained:— Gammaruspal- 
lidus, G. obtusatus, G. Othonis, Lembos Websterii, Ampelisca typicus. 
During the course of the day we landed on the Breakwater, and I 
was much struck by the immense numbers of Allorchestidse—a family 
which has never occurred to me in Dublin. Allorchestes imbricatus 
swarmed all along high water-mark.
