MARINE ZOOLOGY 



In the list that follows records of previous county workers are incor- 

 porated where there is no doubt as to identification, but there may be 

 omissions due to the inaccessibility of some of the literature to one who is 

 working in the country. The writer's observations on the Cornish marine 

 fauna began nearly twenty years ago, and have been continuous over the last 

 seven years. A large amount of shore collecting has been done from the 

 spring of 1900 onwards by his Nature Study and Biology students at the 

 County Technical Schools, and there are few beaches of importance in the 

 south of the county that have not been visited at low spring tides. Trawl 

 refuse has also received a considerable amount of attention, and though the 

 specimens obtained are frequently in poor condition they are generally suffi- 

 cient for identification. A good deal of dredging has been carried out in 

 Falmouth Bay and elsewhere, and some awkward but remunerative work 

 done in thirty-five to forty-five fathoms off the Dodman. A long and 

 valuable fauna list has been kindly supplied by Mr. Rupert Vallentin for 

 Falmouth and the neighbourhood, and a large series of unpublished records 

 by Mr. A. Robinson for the Polperro district. Lists have also been 

 received from Mr. E. Heron Allen and from the late Mr. W. E. Baily for 

 Mount's Bay, and considerable assistance has been given by Mr. Matthias 

 Dunn and other members of the County Fisheries Committee. To these 

 and to his many other helpers and co-workers the writer wishes to express 

 his hearty thanks, not only for what they have done but for the spirit in 

 which their help has been given. To his friend Dr. E. J. Allen, Director of 

 the Marine Biological Laboratory at Plymouth, he is under great obligation 

 for placing the resources of that institution so freely at his service, and for 

 much personal help and advice in the preparation of the article. 



Through the exigencies of space it has been found necessary to adopt 

 the following abbreviations in the lists of species, viz : abund. denotes 

 abundant ; B. bay ; c. common ; dist. distribution, distributed ; esp. especial, 

 especially ; f. c. fairly common ; gen. general, generally ; gnds. grounds ; 

 Harb. Harbour ; h. t. high tide ; h. w. high water ; 1. w. low water ; 

 n. c. not common ; n. unc. not uncommon ; occ. occasion, occasionally ; 

 r. rare ; rr. very rare ; S. Sound ; spec, specimen ; s. t. spring tide ; 

 t-m. tide-mark ; var. variety, variation ; v. c. very common ; w-m. water- 

 mark. 



Among the names of authorities and recorders the following are indicated 

 by initials, viz : Couch, Jonathan = (J. C.); Couch, R.Quiller (R. Q. C.);

FORAMINIFERA 



The following list of county foraminifera is based on the work of the Marine Biological 

 Association at Plymouth, on a MS. list kindly furnished by Mr. F. W. Millett of the Foraminifera 

 of Mount's Bay, on a similar list by Mr. E. Heron Allen of the species taken by him at Poljew 

 Cove, Mullion, in 1892, and on work done by the Biological Department of the County Technical 

 Schools at Truro. Where no authority is given for localities in the Plymouth district the records
