16 TRANSACTIONS, NATURAL HISTORY SOCIETY OF GLASGOW. 



Aporrluiis pes-pelecani, {L.). — Two immature sjaecimens, 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, Link. : 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, off lona 

 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 specijnens 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 

 from 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 iruncalus (Sirum.). — 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" (Praegei*). It occurs in considei'able abund- 

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

 especially on the gravel bank beside Rock House. 

 -.V. incrussata [Strain.).' — In myriads near Ptock House. 

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

 Pleurotoma nebula {Mont.). — Two examples of this rather scarce 

 mollusc. 

 */*. hevif/ata, 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. Pi'aeger does not 

 mention the species at all ; and Jeffreys gives Guernsey as
