occurred on the south coast His mode of preparing animals, particu¬ 
larly the skeletons of fishes, I have never seen surpassed, and seldom 
equalled, and his charges are most moderate. 
In the gardens of the inn at Polperro, Philougria riparia is not 
uncommon; Porcellio scaher, Oniscus fossor, 0. murarius , and Philoscia 
muscorum, as usual, abundant. I was surprised not to be able to find 
Porcellio pruinosus, so abundant in Kent, although I searched several 
likely localities. 
In returning home we took the Cliff-road, and at Talland Cove spent 
a few moments examining the supra-littoral zone (the tide being nearly 
full in). Here, as might be expected, Ligia oceanica, Porcellio sealer , 
Philoscia muscorum , and Orchestia littorea , were abundant; but I was 
much pleased by also meeting with a Philoscia new to me, and also un¬ 
described in the books. This I have named Philoscia Couchii (vide 
“Proceedings, Dub. Hat. Hist. Soc.,” vol.i. p. Ill, “Hat. Hist. Review,” 
ante p. 195), in memorial of one of the pioneers in the study of the 
zoological geography of England, and of a few pleasant hours spent in 
his company. The species appeared abundant, and the following de¬ 
scription of the spot where it occurred may probably aid others in 
finding it. Having descended the hill from Polperro, you cross the 
stream which drains an extensive osier marsh; the road then turns up a 
narrow ferny lane, into a very heavy hill; instead of turning up this 
lane, keep straight on from the bridge, and a few yards brings you up 
at the foot of the cliff. Here, amongst the loose stones and sea-weed car¬ 
ried up by the high tides into the clefts of the slate rocks, in company 
with the other Oniscoids and many Myriopoda, Philoscia Couchii will be 
seen hiding among the shingle, and easily distinguishable from P. mus¬ 
corum, which also occurs, by its uniform colour. 
At Looe, Philougria riparia occurred abundantly among sticks along 
the river side. I looked carefully for Phil, vivida, but could not find it. 
• In and about Plymouth, the following was the distribution of the 
Oniscoids:— Philougria riparia, rare; Philougria rosea (added to our 
lists by C. Spence Bate), abundant in the gardens of that gentleman’s 
house, and also in his cellars. Philoscia muscorum , Porcellio scaler and 
variety, marmoratus, Oniscus murarius, and 0. fossor, all common. Li¬ 
gia oceanica, very common. 
I did not pay much attention to the Mollusca, but the following 
Helices are tolerably abundant:— Helix virgata, II. fusca, II. aspera, 
H. caper at a (Devil’s Point). Helix hortensis and II. nemoralis are by 
no means rare in the Cornish lanes. Several of the latter sported the 
white lip which led Eorbes from the examination of shell specimens in 
collections to fall into the error of uniting the two species, but in all 
the specimens which I obtained the coarse texture of the animal, and 
the colour and texture of the foot, proves the distinctness of the animals. 
Specimens of H. nemoralis with white lips, obtained by me in 
August on the Antrim road, Carrickfergus, confirm this observa- 
vation. Among the specimens of II hortensis obtained were several of 
the curious Albino variety, in which the glands of the mantle not se-
