Fam. XVIIT. Conidce. 

 *Mangelia turricola {Pleurotoma and Fusus turricolus). Scarce in 

 Lanilash Bay. Ayr, Bute, Smith. 



M. rufa (Fusus rufus). Laralash, Landshorough. Var. ulideaua. 

 " Between Fullarton's Rock and King's Cross Point; only one speci- 

 men obtained," Greville and Miles. 



M. sepangularis {Fusus septangularis, Pleurotoma septangularis) . 

 Rare at Lamlash. Ayr, Bute, Smith. 



M. teres. I have dredged one living example of this beautiful 

 Mangelia on the bed of old rotten scallops described under Ptilidium 

 fulvum. Messrs. Greville and Miles took three specimens in Laralash 

 Bay. 



M. Trevelliana (Pleurotoma sinuosa). The Pleurotoma sinuosa is 

 said by Mr. Smith to have occurred at Ayr. 



M. purpurea {Fusus purpureus, Pleurotoma purpurea). A few- 

 specimens between Clachland Point and Holy Island. 1 once met 

 with a dwarf form in some numbers in the large rock-pool of the 

 outer Allans. 



M. Lefroyi [Fusus Boothii, Pleurotoma Boothii). This species 

 was first described as British from specimens taken by Mr. Smith and 

 Professor Forbes in Lamlash Bay, C umbrae. It is frequent in other 

 parts of the Clyde, also among nullipore in the coralline zone. 



M. linearis {Fusus linearis, Pleurotoma linearis). Not uncommon 

 alive in Lamlash Bay, Cumbrae. 



M. gracilis (Fusus gracilis, Pleurotoma elegans). " Clyde in fifteen 

 to twenty fathoms," M^ Andrew. Lamlash, Landshorough. 



M. nebula {Fusus nehulus). Clyde, Bute, Smith. Lamlash, Lands- 

 horough. 



M. striolata {Pleurotoma Smiihii). Rare near Cumbrae. It has 

 also been taken by Mr. Smith and Professor Forbes " in twenty 

 fathoms," Forbes and Hanley. 



*M. costata {Fusus costatus, Pleurotoma costata, Pleurotoma co- 

 arctata). Occasional in deep water. 



M. attenuata [Fusus attenuatus). Inserted in Dr. Landsborough's 

 lists, but probably in error. Mangelia striolata was probably mistaken 

 for it, as that species does not occur in the lists, at pp. 160 and 363, 

 of the * Excursions' which give Fusus attenuatus. 



Fam. XIX. Cyprceadce. 

 Cyprsea europgea [Bulla Candida, B. diaphana). Frequent.
