assigned by the older writers may be found erroneously placed. The follow- 
ing are probably from the West coast of North America, with the synonymy 
as understood by Dr. Gray :—

But the first authentic information on the molluscs of the North-western 
coast is given in the ‘ Voyage Round the World, but more particularly to the 
N.W. Coast of America,’ by Capt. George Dixon, London, 1789: to which is 
added a Natural History Appendix. 
Page 355, fig. 2. Solen patulus*, Cook’s River. [=Machera Nuttalli, Cony. ] 
In the ‘ Conchology, or Natural History of Shells,’ by George Perry, Lon- 
don, 1811, a work of no little pretension, yet singularly inaccurate, are figured 
the following species, but without authorities for the assigned localities :— 
* As this extract is probably the first description on record of molluscs from the Pacific 
shores of N. America, by the original collector, and as the book is rarely to be met with, 
it may be interesting to quote the passage :-— 
“At the mouth of Cook’s River [lat. 59°-61°] are many species of shell-fish, most of 
them, I presume, nondescript; and of all which I should have endeavoured to have got 
specimens, had business permitted. Among the bivalves we noticed some of a large spe- 
cies, of the Cardium or cockle-genus [ Cardiwm corbis, Mart. }, half-a-dozen of which would 
have afforded a good supper for one person; but, for a repast of that kind, our men pre- 
ferred a large species of the Solen genus, which they got in quantity, and were easily dis- 
covered by their spouting up the water as the men walked over the sands where they in- 
habited: as I suppose it to be a new kind, I have given a figure of it in the annexed plate 
‘[Solen patulus ; accurate external and internal views, size of life]. Tis a thin brittle shell, 
smooth within and without: one valve is furnished with two front and two lateral teeth 
[the ‘laterals’ are the nymphe for the ligament]; the other has one front and one side 
tooth, which slip in between the others in the opposite valve : from the teeth, in each valve, 
proceeds a strong rib, which extends to above halfway across the shell, and gradually loses 
itself towards the edge, which is smooth and sharp. The colour of the outside is white, 
circularly, but faintly, zoned with violet, and is covered with a smooth yellowish-brown 
epidermis, which appears darkest where the zones are: the inside is white, slightly zoned, 
and tinted with violet and pink. The animal, as in all species of this genus, protrudes 
beyond the ends of the shell very much, and is exceeding good food.—A fine specimen of 
this kind is in the Collection of John Swainson, Esq., of the Custom House, London.—We 
saw also, on this coast, a kind of muscle, in colour and shape much like the common eat- 
able muscle of Europe, but differed in being circularly wrinkled, and a great deal larger 
[Mytilus Californianus, Conr.]. One valve I saw at Queen Charlotte’s Islands measured 
above nine inches and a half in length.— With pieces of these muscles, sharpened to an ex- 
quisite edge and point, the Indians head their harpoons and other instruments for fishing. 
They fasten them on with a kind of resinous substance,”—Dizxon’s ‘Voyage.’
