18 LIVERPOOL MARINE BIOLOGY COMMITTEE REPORT. 



Mr. Byerley's Fauna recorded the occurrence of more than 

 one specimen of the bottle-headed Dolphin, Hyperoodon ; 

 also of the Dormouse and of the Marten. 



The Mollusca of the district, land, fresh-water, and 

 marine, are represented in Mr. Byerley's Fauna by a fine 

 series of 181 species, of which 123 are marine ; most of 

 them, with many others, have been more recently taken 

 within our area. The local workers in marine shells, most 

 frequently quoted, are Dr. Donald Cameron, Mr. Webster of 

 Upton Hall, Mr. F. P. Marrat, and for the shell-less marine 

 species, Mr. John Price. 



To the north of Anglesea, within our area, must be some 

 dredging ground very prolific in the Mollusca ; for about the 

 time when Mr. Byerley's Fauna was printed, the writer spent 

 three days on the sands and low rocks of Red-wharf Bay, 

 eight miles from Beaumaris, and succeeded in collecting 84 

 species, an unusual number to be obtained without the use 

 of boat or dredge. 



Not long after, whilst the writer was collecting with 

 Mr. Byerley, on Caldy Blacks, in the river Dee, one lovely 

 midsummer's morning, betwen four and five a.m., the in- 

 coming tide, approaching from Daw-pool Deeps, cut us off, 

 and though we rushed to our trap, and drove as rapidly as 

 possible through the impatient stream, for a time it seemed 

 more than likely that the horse would have to swim, and the 

 trap be upset. I venture to recommend the members of the 

 Marine Biology Committee, visiting Caldy Blacks during the 

 low spring-tide of a June morning, to place a sentinel on the 

 out-look, as a possible substitute for their own fascinated 

 powers of attention to environments. The following species 

 were found at Caldy Blacks : — Venus fasciata, a valve, 

 Trochus cinerarius, Chiton cinereus, Doris, three species, 

 EoliSy one species, and many Hydrozoa. 



In the Crustacea, Byerley's list of 70 species includes
