810 General Notes. -[November, 
until reports came from you at Newport. They opened one and 
found in its stomach the ordinary red mackerel food, This crew 
differ with the crew of the schooner Fitz. Y. Babson with regard 
to the ease of capturing them—think them rather difficult to 
take; say they flip like porgies, and do not rush like mackerel; 
they saw ten large schools of them on Saturday last when some fif- 
teen miles south of Block island. 
I hope that any reader of the AMERICAN NATURALIST who has 
seen this fish will mention it; some may, perhaps, have an oppor- 
tunity of studying its habits. The length of those I have seen 
ranges from twelve to sixteen inches, and their weight from three- 
quarters of a pound to a pound and a-half or more. Those sent 
to New York market were part of the lot taken by the schooner 
American Eagle and brought into Newport, whence they were 
shipped by Mr. Thompson, a fish dealer of this place. It would 
require from eighty to one hundred of them to fill a barrel, so the 
estimate of Capt. Riggs that there are a thousand barrels in one 
of the schools, shows how exceedingly abundant they must be. 
Capt. N. E. Atwood, of Provincetown, Mass., the veteran fish- 
erman-ichthyologist, has examined the specimens, and is satisfied 
that they belong to the same species as fish which he found 
abundant in the Azores in 1840, when, led by the reports of Cape 
Cod whalers, he went to these islands in search of mackerel, the 
mackerel fishing being poor at home. No mackerel were found 
except the “ frigate mackerel” referred to in this note.— G. Brown

ON THE OCCURRENCE OF FREIA PRODUCTA WRIGHT, IN THE 
CHESAPEAKE BAY.—Sometime in 1851 Prof. Leidy called attention 
to the existence of Freia ampulla in American waters, and from 
the poor figures of the European form then in existence, he was 
led to consider it a new species under the name of F. americana, 
but he now considers both forms the same. As they are amongst 
the most singular and beautiful of the family of the trumpet ani- 
malcules or Stentorina, I take pleasure in announcing that I have 
found the still more interesting species, F. producta T. S. Wright, 
in shallow waters on the western shore of the Chesapeake, at- 
tached in vast numbers to the shells of oysters, in company W1 
? Loxosoma and other bryozoa. 
The tubes in which the animalcule resides are formed of a nar- 
row transparent ribbon of horny consistency, wound into a spiral 
and terminating in a trumpet-shaped extremity from which the 
_odd peristome of the inhabitant protrudes. The basal or attached
