270 BET. B. B. WATSON ON THE 



very valuable collection, the accumulation of very many years. 

 The mutual relations of these different collections are supplied 

 in the following list, where, for the sake of shortness, M. repre- 

 sents McAndrew; L., Lowe ; N., Nobre ; Jn., Johnson; and 

 W., Watson. 



If my reference to dredgiug-depths is somewhat indefinite, it 

 is so left on purpose. Unable personally to superintend this 

 dredging, I have only the boatmen's testimony to the obedience 

 reudered to my order that dredging should go down to 50 fms. 

 One, indeed, of my four boatmen was honest, but truthfulness 

 is not a notable characteristic of the Funchal boatmen ; and it is 

 not in human nature, uncoerced, to do more troublesome work 

 at 50 fms. than the easier at 20 or 30 — especially when to those 

 engaged the work appears silly, and their employer is regarded as 

 a madman. 



I have gratefully to acknowledge counsel and help from the 

 late Dr. Gwyn Jeffreys, from Mr. Edgar A. Smith of the British 

 Museum, and from the Marquis of Monterosato. To the last 

 especially I am indebted for determining (and that with Medi- 

 terranean specimens sent me for comparison) the very hopeless 

 wave-beaten fragments of Vermetidse with which I have had 

 to deal
