MOLLUSCA AND BRACHIOPODA OF THE IRISH 



ATLANTIC SLOPE 



Between 50 and 1000 Fathoms. 



By ANNE L. MASSY. 



(Read before the Society, June 9th, 191;). 



TiiE species noted here were taken during investigations carried out 

 on board the fishery cruiser " Helga " of the Department of Agri- 

 culture and Technical Instruction for Ireland. Complete lists of all 

 the moUusca and brachiopoda collected will be published later by the 

 Department. 



In the list of captures given below it must be understood that a 

 record of number of specimens only implies that the specimens were 

 taken alive. When only empty .shells were taken, the record of 

 number is followed by " shell " or " shells." 



Canon Norman and Mr. E. A. Smith kindly verified several species 

 and their initials follow the determinations made by them. Mr. 

 E. R. Sykes identified Solariella ottoi (Phil.) too late for inclusion in 

 his paper on the molluscs and brachiopods of the deep water off the 

 west and south west coasts of Ireland.^ 



M. Edouard Lamy kindly helped me to compare a shell of Scala 

 ridiardi (Dautz. & de Boury) with the type in the Paris Museum. 

 Mr. Robson, of the British Museum, identified Coccnii/ia galeola 

 (Jeff.) adding, however, that it was "an identification quite open to 

 question." 1 am indebted to ]\Ir. Nichols, of the Dul)lin Museum, 

 for allowing me to examine many specimens in the Monterosato 

 Collection.
