AG PROCEEDINGS OF UNITED STATES NATIONAL MUSEUM: 
I was unable to procure even a specimen of the salmon, but obtained 
enough smelts to forward some excellent specimens to Washington. 
Very respectfully, your obedient servant, 
JAMES G. SWAN. 
Prof. SPENCER F.. BAIRD, . 
United States Commissioner Fish and Fisheries, 
Smithsonian Institution, Washington, D. C. 
P. S.—I omitted to mention that the surf-smelt are common in all the 
salt water of Puget Sound, but I have not heard of an instance where 
they run up fresh-water streams to spawn, like the eastern smelt.

NOTE ON THE OCCURRENCE OF PRODUCTUS GEIGANTEUS IN CAL- 
IFORNITA. 
By C. A. WHITE. 
Among a small collection of fossils sent to the National Museum by Mr. 
Ludwig Kumlien, of the United States Fish Commission, from the valley 
of McCloud River, Shasta County, California, are three or four large ex- 
amples of Productus, which I am unable to distinguish from P. giganteus 
Martin sp., the well-known type species of the genus as it is extensively 
known in European strata. They are preserved in a hard, dark-colored, 
argillaceous rock, which is partly metamorphosed, and they are, there- 
fore, somewhat imperfect; but portions of them show the characteristics 
of the species very plainly. The largest of these Californian examples 
was, when perfect, quite equal in size to the larger European examples 
of P: giganteus, having had a transverse diameter near the hinge of not 
less than 140 millimeters, or 55 inches. 
A small collection of fossils was sent by mail from the same locality in 
1877 by Mr. Livingston Stone, the species of which were recognized as 
of Carboniferous age, but P. giganteus was not among them, although 
the later collections indicate that they occur in the same strata. These 
associated forms of both collections are too imperfectly preserved for 
specific determination, but the genera I’enestella, Streptorhynchus, Spiri- 
gera Camarophoria, Allorisma, and Huomphalus are more or less satis- 
factorily recognized. They all together plainly indicate tho Carbonif- 
erous age of the strata from which they come, which fact was also 
previously known through the reports of Trask and Whitney. 
This, so far as I am aware, is the first discovery of P. giganteus in 
American strata. It is not a little remarkable that it should be found 
in the western portion of the continent and not in the middle and east- 
ern portions, where the Carboniferous system is so well developed, and 
where several European species of Carboniferous brachiopoda are recog- 
nized.
