A naturalist’s ramble in guernsey. 
Amongst the Turbellaria found the most curious one was 
Neme^'tes j^urpurea, which was kept alive for several days in an 
improvised aquarium, and its peculiar mode of progression and 
habits observed. Not the least interesting marine production 
was a large broken mast w^ashed ashore at Bordeaux Harbour, a 
little to the north of St. Sampson’s, which was found riddled 
by shipworms, and its lower submerged half covered with 
Barnacles (Lepas) in such masses, as would have more than 
filled three carts, and the salmon-coloured peduncles of which, 
12 to 18 inches long, were twisting and writhing in snake-like 
fashion as long as the poor creatures were alive. 
On the shore, too, especially on the eastern part of the 
island, one often finds small heaps of Ormer-shells or Ear-shells 
(Haliotis tuberculataj, of which the Channel Islands are our 
nearest station ; but these have not been thrown up by the sea, 
but are the deposits of man, for these molluscs are collected at 
extreme low water, especially during the highest spring tides in 
March and April, and brought to market, or enjoyed by the 
collectors themselves. The few that were obtained among the 
rocks at low- water at the time to which this account refers 
(August) were small, but served on that account all the better 
for the preparation of their most heautiful Odontophores or 
tongues as microscopical objects. 
The waters around Guernsey seem to be particularly rich in 
Polyzoa, a group of animals in which the author is specially 
interested. Of the following species collected in Guernsey 
(named according to Hincks’ Monograph of British Polyzoa) not 
less than 62 were obtained in the one dredging operation between 
Guernsey and Herm, of about four hours’ duration, referred to 
above, and were brought home dried, for the purpose of identifi- 
cation. The remaining nine species are only a few of those 
that were gathered along the shore, and mounted for the micro- 
scope with their tentacles extended — the rest, refusing to be
