398 REPORT—1840. 
Carcharias vulgaris has not been properly established as a 
British species ; the Zygena malleus has but once been taken ; 
Scymnus borealis twice, and in both instances north of the 
mainland of Scotland. Echinorhinus spinosus is a late addi- 
tion to the British catalogue, and has been obtained in different 
localities on the English coast. 
Scyllium Canicula, Spinax acanthias, Mustela levis and 
Galeus vulgaris are the most common species; the first the 
most so, the others becoming less so in the order in which they 
are set down. They are found from north to south. Carcha- 
rias glaucus, Lamna Cornubica or Monensis (these I am dis- 
posed to believe are but one species), and Squatina Angelus 
are of occasional but rare occurrence from north to south. 
Templeton notices Scyllium stellare as taken occasionally ; and 
Carcharias Vulpes as having been seen about the Copeland Isles, 
near the entrance of Belfast Bay. Selachus maximus, the 
** Sunfish” of Ireland, and so valuable for its oil, prevails on 
the western and southern coasts, but chiefly on the former. 
Of the Pristiurus melanostomus, two individuals have been ob- 
tained by the collectors of the Ordnance Survey at Portrush, 
near the Giant’s Causeway*.

* Captain Portlock, in contributing a notice of this Shark, observed, that 
“in the work of Miiller and Henle the genus Pristiurus, Bonap. is described 
as having a row of small prickles on the tail-fin, and Scyllium Artedi is figured 
and described by Risso as having but a single row. In Yarrell’s description 
of Scyll. melanostomum, two rows are mentioned, and in our specimens they 
certainly exist. Ought not, therefore, the single row to be dropped as a generic 
character, and Risso’s termination of his specific characters used, viz. ‘ pinna 
dorsi extremitate [supra] spinosa’? May not the one and two-roed indivi- 
duals be of distinct species, and the black mouth be common to both ?” 
+ Captain Portlock informs me that accurate drawings of a species of Ray, 
obtained during the Ordnance Survey of Antrim, and submitted to Mr. Yarrell 
and Mr. Couch, were considered by these naturalists to represent this species.
