coast, together with ‘‘ Myatruncata.” The two species I saw in 
Anticosti, possess precisely the same habit. I regret I did not 
bring back with me a few of the living shells, but I secured a 
great number in a fossilized state from the blue ‘‘Leda Clay” 
of the island, and they agree exactly with the European shells. 
They first put in an appearance in the ‘‘ Miocene,” but the 
Corbula (basket shell) occurs as far down as the Mesozoic age. 
The writer received from the Smithsonian Institute a few years 
ago, the fossilized specimen of a Panopea, a Mya now in one of 
the small cases. The ‘‘Panopea Australis” at the Cape, buried 
in the sand at low water toa depth of several feet. ‘‘Saxzcava” 
is found to be very destructive to the Plymouth breakwater. 
An English naturalist states: ‘‘It has been honeycombed by the 
Mollusc six or more inches deep.” I obtained no living ones, I 
think, at Anticosti, but several in the Leda Clay. They range, 
Woodward says, from low water to 140 fathoms, and he adds, 
the British specimens (Panopea) have been caught accidentally 
by deep water fishing hooks. In Mrs. Carey’s collection you may 
notice some fine specimens of the Cardiadz, from the Californian 
coast. The Cockle of the Old Country ‘‘ Cardium Edule, ” fre- 
quents sandy beaches. Numbers of women in Ireland are em- 
ployed in collecting the heart-shell for market. It was, I believe, 
instrumental in saving many lives during the famine in the island 
along the sea-coast. Like the Razor shell when it burrows in 
the beach, it leaves a mark which betrays its habitation. This 
species has been found in the ‘‘ Norwich Crag.” Sub-genera 
have been recognized as far down as the upper Silurian age, 
and not long since, the writer sent to the survey office, Ottawa, 
a Conocardium from the Ontario Devonian Rocks, which bore 
a near resemblance to C. Alifoyme, (Sowerly), of the mountain 
limestone in the south of Ireland. The ‘‘ dvzculide” or Wing- 
shells, to which the well-known pearl oysters belong, have 
attracted much attention from a very early age, (the so-called 
Hammer Head Oyster is also a member of this family). Ceylon 
and the Red Sea were formerly famous for their valuable pearl 
fisheries, but long since, travellers pointed out that unless steps 
were taken to preserve the Molluscs, the supply must assuredly
