THE FISHES OF THE IRISH SEA. 65 
ScyLLIuM CATULUs, Gunn.—Nurse-hound. 
(Day’s British Fishes, vol. II., p. 312, Pl. CLIX., Fig. 2.) 
This larger spotted dogfish is found round the coasts of Europe generally, but is not so 
common in our seas as the last species. It is occasionally taken off Port Erin and round the 
Isle of Man; and Prof. White tells us he has taken one, 34 feet long, this year in Carnarvon 
Bay. 
PRISTIURUS MELANOsTOMUs (Rafin.)—Black-mouthed Dog’fish. 
(Day’s British Fishes, vol. II., p. 314, Pl. CLX., Fig. 1.) 
(Fish. Mus., Zool. Dep., Univ. Coll., Liverpool.) 
This dogfish occurs throughout N.W. Europe and the Mediterranean, and is sometimes 
found in our district. We have a local specimen in the College Museum. 
Family Sprnacip&. 
ACANTHIAS VULGARIS, Risso.—Pieked Dog-fish. 
(Day’s British Fishes, vol. II., p. 315, Pl. CLX., Fig. 2.) 
(Fish. Mus., Zool. Dep., Univ. Coll., Liverpool.) 
This common Dog-fish has a wide range in temperate seas. It occurs in great 
abundance all around our coasts. It is commonly taken on cod lines and in trawl nets in our 
district ; frequently on long lines around the Calf, Port Erin. 
ECHINORHINUS spINosus (Cuy.)—Spinous Shark. 
(Day’s British Fishes, vol. II., p. 323, Pl. CLXII., Fig. 2.) 
This Shark has a wide distribution, from the north of Europe to the Cape of Good Hope. 
It has been recorded from many points round the British coast, including one in our district. 
“Mr Moore has recorded one from Ireland, captured September 25th, 1882, near Skerries, 
about 15 miles to the north of Dublin” (Day). 
Sub-order II. TECTOSPONDYLI. 
(Skates and Rays). 
If the centra of the vertebra are calcified, it is in the form of concentric rings. Spiracles 
are always present. Large pectoral fins, fused with and surrounding the sides of the head ; 
body usually flattened dorso-ventrally. The tail fin is feeble, and there is no anal fin; gill-slits 
on the ventral surface, and spiracle on the dorsal. 
Family Rumi. 
Runa sguatina (Linn.)—Monk-fish. 
(Day’s British Fishes, vol. II., p. 326, Pl. CLXIIL.) 
(Fish. Mus., Zool. Dep., Univ. Coll., Liverpool.) Local name, ‘‘ Abbot.” 
The ‘‘ Monk,” or “ Angel-fish,” has almost a world-wide distribution, and is common 
off our coasts in spring and summer. It occurs not unfrequently in the trawl net in the 
Lancashire district. We have taken it as near Liverpool as the Rock and Horse Channels,
