THE NAUTILUS. 21 
the little Unios, and over a pint of the univalves. They were evi- 
dently making their way up stream, excited to do so by the strong 
millrace current. Many of them were busily working their shells 
out of sight in the coarse sand, and if we had been an hour or so 
later, perhaps none would have been visible. 
Having collected all we desired of these two species, we went be- 
low the deep hole, and, in water from one to two feet deep, collected 
all we cared to haul home of the following species : 
Unio alatus Say. A few. 
Unio anodontoides Lea. Very plentiful and fine, ranging in size 
from full grown ones seven inches long to the very small young ones 
an inch in length; and both varieties, the plain brown colored and 
the beautifully rayed ones. 
Unio occidens Lea. Some very good ones. 
Unio gibbosus Barnes. Only a few found, along with its cousin, 
the anodontoides, and U. rectus Lamarck, a half-dozen. 
U. gracilis Barnes. Quite plentiful. 
U. lachrymosus Lea. Some nicely marked ones. 
U. ligamentinus Lam, More numerous than any other mussel in 
this locality. Specimens 5 to 7 inches long, were nicely rayed and 
but little eroded on the beaks. 
Unio multiplicatus Lea. Four or five of the gigantic ones, 7 to 82 
inches long and a foot in circumference. 
U. plicatus Lesueur. Plentiful,and all sizes. 
U. tuberculatus Barnes. Plentiful, and all sizes, from 7 inches 
down. 
Margaritana rugosa Barnes. A few adults found. 
M. complanata Bar. Very plentiful and very fine, all sizes, from 
the beautifully-rayed young specimens, to the full sized adults pecu- 
liar to this river. One lying before me as I write, is 82 inches long 
and thirteen inches in circumference. 
This water was too swift and the bed of the river too rocky for the 
Anodons, and only a few edentula Say and grandis Say were found. 
Having loaded our boat with only the finest ones, and as many as 
we could get in our buggy, we pulled back up to the town, loaded 
up and departed for home, well satisfied with our day’s outing. 
A Visit To A VESSEL THAT WAS LOADED wITH SHELLS.—This 
winter I was much interested in a vessel which came into the port 
of Boston loaded with nothing but shells. I obtained a beautiful 
specimen of Spondylus, pink with white spines, and I can find noth-
