16 TRANSACTIONS, NATURAL HISTORY SOCIETY OP GLASGOW. 



Aporrhciis jies-pelecani, (L.). — Two immature specimens, without 



the adult " webbed-foot." 

 Cerithium reticulatum (Da C). — Moderately abundant in gravel 

 beds near Rock House. 

 * Purpura lapillus {L.). — Very common on rocks near Rock 



House. 

 *P. lapillus, var. imbricata, Lmk. : with the type. — Not referred 

 to in Praeger's list; nor have I any records of its occurrence 

 in Clyde waters. It has been taken, in 20 fathoms, offlona 

 by Mr. Somerville. 



Buccinum undatum, L. — Common. 

 % Murex erinaceus, L. — Found dead in abundance, and generally 

 much worn. Jeffreys gives a list of British stations, and 

 remarks — " All the specimens procured from the northern 

 coasts were dead" (B. C, vol. IV., p. 308). But Mr. 

 Praeger has been fortunate enough to dredge it alive, in 

 3 fathoms, off Rockport, Belfast Lough, which, I understand, 

 is a solitary record for its living state. Brown omits it- 

 f rom his Clyde list ; Smith quotes Bute and Ayr as places 

 where it has been found ; Forbes mentions " the Clyde, 

 15 fathoms, dead"; and Mr. Somerville has taken it at 

 Ardrossan. It is got in Oban Bay, but commonly dead 

 and worn. 



Trophon truncatus (Strom.). — Two examples obtained. 



Fusus antiquus (L.) — Common. 



F. gracilis (Da C). — Sparingly on Port-Stewart sands. "I have 

 not observed it on the Derry Coast " (Praeger). 

 *Nassa reticulata (L.) — " I have dead shells from Portrush and 

 Magilligan" (Praeger). It occurs in considerable abund- 

 ance along the broad sands of Port-Stewart, but more 

 especially on the gravel bank beside Rock House. 



N. incrassata (Strom.). — In myriads near Rock House. 



Defrancia linearis (Mont.). — Only one specimen. 



Pleurotoma nebula (Jlont.). — Two examples of this rather scarce 

 mollusc. 

 *P, Icevigata, var. minor, Jeff. — It would seem that the two 

 specimens which I obtained of this variety are a new 

 record for the North Irish coast. Praeger does not 

 mention the species at all ; and Jeffreys gives Guernsey as
