THE ZOOLOGIST. 



Quiller Couch, of Penzance, W. P. Cocks, of Falmouth, Spence 

 Bate, of Plymouth, G. F. Tregelles, of Penzance, and Kupert 

 Vallentin, of Falmouth and St. Ives, are the most conspicuous 

 among the former ; and Victor Cams, Dr. Brady, Dr. Robertson, 

 of Cumbrae, and the Rev. Canon Norman among the latter. 

 Admirable work has also been done by the Marine Biological 

 Association in the waters about Plymouth Sound. In spite, 

 however, of the work of many distinguished carcinologists, the 

 summary of previously published records prepared by the Rev. 

 T. R. R. Stebbing for the 1 Victoria History of Cornwall,' and 

 even the recent ' Crustacea of Devon and Cornwall,' by Canon 

 Norman and Dr. Scott, though remarkable as lists of species, 

 indicate in a striking fashion how extremely fragmentary is the 

 available knowledge of local distribution. In Stebbing's com- 

 pilation many of the species have not been recorded for sixty 

 years or more, and in a number of cases the occurrence of a 

 relatively common species in county waters is indicated only by 

 a quotation from Cocks (1849) or Jonathan Couch (1838). Canon 

 Norman's work contains the results of his own extensive investi- 

 gations in Cornish and Devonshire waters, and is probably the 

 most complete account of the Crustacea of any district in Great 

 Britain. Even there, however, large stretches of coast-line and 

 sea-bottom on the south are never mentioned ; while, except 

 for St. Ives, the Bristol Channel remains practically a mare 

 incognitum. 



The following notes are based on the results obtained 

 by shore-collecting, dredging, trawling, and the examination 

 of trawl-refuse in 1887-8, during the summer of 1890, and 

 continuously from 1899 to 1908. Shore-collecting has been 

 assiduously practised by the writer and his pupils all round the 

 coast from Portwrinkle to Bude, with the exception of the stretch 

 between Kynance Cove and Loe Pool, and of that between Port 

 Isaac and Millook. The shores of Falmouth Bay from the 

 harbour to the mouth of Helford River have naturally received 

 most attention. Next in order come Gerrans Bay, Millook, 

 Hayle, the unprofitable beaches about Newquay and Perran- 

 porth, the happy hunting-ground from Polperro round to Gorran 

 and the sheltered coves from Lamorna to Sennen. The beaches 

 and flats of St. Mary's and Tresco, and the stormy shores and
