five feet in length. Sharks of different kinds have been rather plentiful 
on the coasts of Devon and Cornwall during the prevailing hot weather. —

Torpedo marmorata at Mevagissey.—On the 25th June last a female 
specimen of Torpedo marmorata was caught in a trawl-net in Mevagissey 
Bay. It measured about eighteen inches in length by eleven inches in 
width, and weighed about six pounds. ‘The general colour of the back was 
light brown, with a shade of yellow in it, and mottled with white spots 
over the entire surface, except that directly over the electrical organs the 
spots coalesced so as to form an extensive white patch. ‘The spiracles 
behind the eyes were large and oblong, with seven or eight protuberances 
attached along the inner edge. A strange circumstance in connection with 
this creature is its being affected by parasites, some of which, very much 
like leeches, were attached to its back, and presumably must be proof 
against an electrical shock.—Marruias Dunn (Mevagissey). 
Habits of the Lesser Weever.— The Lesser Weever, Trachinus 
vipera, has a habit of taking shelter at night under the sand of the sea- 
bottom. I had this information from two friends who went to Portmelon 
beach here to dig Launces out of the sand with a shovel, one using the 
implement, the other holding a light and gripping hold of the fish on their 
being turned up. The light-holder made a rush at what he thought was a 
large Launce, but found to his cost he had got hold of a “ Viper Weever,” 
for the spines of the creature instantly entered his hand. The usual length 
of this fish is four or five inches, the colour yellowish brown, and the body 
relatively deeper than that of the Greater Weever, Trachinus draco.— 
Marruras Dunn (Mevagissey, Cornwall). 
MOLLUSCA. 
Pisidium roseum at Fulham.—It may interest some of your readers 
to know that Pisidium roseum, Schlotz., occurs in great profusion at 
Fulham, Middlesex. It is associated with Spherium corneum, Pisidium 
pusillum, Bythinia tentaculata, Valvata piscinalis, V. cristata, Planorbis 
nitidus, P. albus, P. vortex, P. complanatus, P. corneus and var., P. con- 
tortus, Physa fontinalis, and Limnea peregra.—Sypnry GC. CockERELL 
(Bedford Park). 
CEPHALOPODA. 
Octopus at Mevagissey, Cornwall.—About the end of June last a 
large Octopus vulgaris was landed here; the stretch of its arms covered 
five feet four inches, and the number of its sucking discs was about 1500, 
some of which were an inch in diameter.—Marratas Dunn (Mevagissey).
