SOME NEW MARINE MOLLUSCA FROM 

 TANGIER. 



By GEORGE W. CHASTER, M.R.C.S. 



Before proceeding to describe the shells referred to in the title 

 of this paper, it may not be out of place to describe briefly how 

 they came into my possession. About two years ago my friend 

 Mr. H. Sidebottom, being engaged in the study of the 

 Foraminifera, requested his relative, Mr. C. H. Nevill, of 

 Bramall Hall, Cheshire, who was about to join a Mediterranean 

 cruise, to bring back bags of anchor-mud and dredgings from 

 the various places touched at. Other dredgings from the 

 Adriatic and from a second cruise made last year were also 

 obtained. These collections of material were with great 

 readiness placed at my disposal to be examined for mollusca. 

 Their range extends from Tangier to Smyrna, including many 

 localities in the Mediterranean, Adriatic, Gulf of Corinth, and 

 Aegean Sea. Although the quantity of material was compara- 

 tively small, the bags of dredgings weighing but a few pounds 

 each, over two hundred species have been obtained therefrom. 

 As might be expected these are almost all minute in size, there 

 being hardly any measuring over half-an-inch. Amongst them, 

 however, are many of considerable rarity and a few apparently 

 new. To my friend the Marquis of Monterosato I must express 

 my sincere thanks for the unfailing courtes}' and readiness with 

 which he has examined and identified the various forms, often 

 after laborious search. 



The material from Tangier consisted of a bag of dredgings 

 from about seven fathoms, and a quantity of shore sand brought 

 on board for the purpose of deck-scrubbing !
