164 CATALOGUE OF THE MOLLUSCA 
the latter, are seen on either side. The muzzle is very large 
and broadly bilobed. This animal evidently is very different 
from that of Velutina levigata, but the drawings we made are 
too imperfect to establish a generic character upon.* 
66. LAMELLARIA, Montagu. 
1. L. persprova, Linn. 
Bulla haliotoidea, Mont. Test. Brit. 211, t. 7, f. 6. 
In shallow water, rare. Several specimens have been got 
from the fishing boats at Whitburn, by the Rev. G. C. Abbes. 
The shell has also been found cast on shore at Whitley.—J. H. F. 
2. L. tentacunata, Mont. 
Lamellaria tentaculata, Mont. in Linn. Trans. xi. 186, t. 
IESE tay, 
Coriocella tentaculata, Johns. in Berw. Club Proce. i. 275. 
Among rocks at low-water mark, Cullercoats. Rather rare. 
Orper. SCUTIBRANCHIATA, Cuvier. 
Famity. Fissureviipz, D’Orbigny. 
67. EMARGINULA, Lamarck. 
1. E. rrssura, Linn. 
Patella fissura, Mont. Test. Brit. 490. 
From the fishing boats, rare. The shell is occasionally found 
in sand. 
68. PUNCTURELLA, Lowe. 
1. P. noacuina, Linn. 
Fissurella noachina, Thorpe Brit. Mar. Conch. 134, f. 78. 
We got a living example of this species adhering to a Fusus 
antiquus brought in by the fishermen at Cullercoats in 1842. 
Mr. W. King subsequently dredged an individual “in 50 fathoms 
water 60 miles to the east of the north coast of Durham.” One 
or two dead and worn shells have been got from the deep-water 
fishing boats. 
* While these sheets are going through the press, we have received from 
Mr. Gray, of the British Museum, his valuable “ List of the Genera of Recent 
Mollusca,” in which we observe that the genus O/ina is proposed for this spe- 
cies.
