: the 9 species not British or Mediter- 
Nore A.—The twenty-four species in the Coralline Crag are the following, viz. Erato mangerie, which 
is West Indian; Nassa granulata, which is Japanese ; Pyrula reticulata, a tropical form ; Zrophon Costifer, 
Pleurotoma hispidula, Cerithium cribrarium, Chemnitzia varicula, Sigaretus excavatus, Bullea ventrosa, and 
Lascea pumila, which are reported by Mr. Jeffreys to have occurred in the abyss of the Atlantic ; Cancellaria 
mitreformis, and Scalaria obtusicostata, which he reports as West Atlantic ; Trochus multigranus, Neera 
obesa, and N. jugosa, which he reports from Atlantic and Lusitanian abysses (and the two first of which are 
also Scandinavian) ; Scalaria subulata, which he reports from the Canaries; Bulla conuloidea, which he 
reports from the Lusitanian Coast ; Cecum mammillatum and Skenia ovata, identified by Dr. P. Carpenter 
with Pacific shells; Cardita scalaris, another Pacific shell; Gastrana laminosa, a South African shell ; 
Natica pusilla and Nucula proxima, species inhabiting the coast of the United States; Cerithiopsis luctea, 
which, if identical with the Crag shell, (of which Iam doubtful) is the only exclusively Arctic species 
among the twenty-five.
