rock pools of Annet, have also received a fair amount of atten- 

 tion. Falmouth Bay, Gerrans Bay, Mevagissey and St. Austell 

 Bay have been explored by dredge and trawl, and frequent visits 

 paid to most of the trawling grounds in 20 to 45 fathoms along 

 the south coast from the west of Hand Deep to the Wolf, and 

 especially to the south of the Gull Bock, Porthscatho. Whit- 

 sand Bay East has been partly explored from Kame Head to the 

 edge of the rocky bottom from which arise the Sherbeterry Kocks 

 and the Knight Errant Patch, and a good deal of difficult but 

 productive work done down to 50 fathoms in the south of the 

 Dodman. The inshore waters to the south of the Manacles 

 have been occasionally visited, and some days have been spent 

 dredging in Mount's Bay and round the coves to the west of 

 Lamorna. On the north coast some work has been done at 

 Zennor, in 20 to 25 fathoms a few miles north of Point Navax, 

 down to about 18 fathoms around Chapel Porth, from shallow 

 water downwards about Padstow and somewhat casually else- 

 where. By dredging and by the help of trawlers several channels 

 and various patches of the outside waters at Scilly have been 

 cursorily investigated, with results that greatly exceed expecta- 

 tion. Large quantities of localized trawl-refuse have been 

 received from the western half of the south coast, from Scilly 

 and from the Bristol Channel. 



References to the works of Couch, Cocks, Bate, Norman and 

 others are made chiefly in the case of rare species, exceptional 

 occurrences and irregular distribution. Frequent use is made 

 of the 1 Journal ' of the Marine Biological Association (M.B.A.) 

 for distribution in the Plymouth district and of Vallentin's 

 records for St. Ives. 



The writer again takes the opportunity of expressing his 

 great indebtedness to fellow-members on the Fisheries Com- 

 mittee of the county, and especially to Mr. Matthias Dunn 

 and to Mr. E. J. Pezzack, the County Fishery Officer, for 

 assistance of a kind that mature experience alone could give ; 

 to Mr. G. F. Tregelles, Barnstaple, to Mr. Rupert Yallentin, 

 St. Ives, and to Dr. E. J. Allen, of the Marine Laboratory, 

 Plymouth, for valuable advice and personal help ; to the 

 fishermen in Cornish and Scillonian waters for systematic 

 observations, abundant material and trawling facilities ; and to
