DALL] REVIEW OF AMERICAN VOLUTID. ae 
39° Fahr., to a point off San Diego, Cala., where it was dredged by 
’ the U. S. steamer Albatross in 822 fathoms. 
U. S. Nat. Mus., 109,001-3, 122,586, 122,600—1, 123,600. 
The species is larger than the Greenland shell, and finely spirally 
striated all over, while, with the exception of a few coarse spirals 
near the canal, the Greenland species is smooth. 
Note.—In the synonymy of the species enumerated in this paper, 
while pointing out that a number of the varietal names proposed 
by Lahille are preoccupied in the genus Voluta, I have refrained 
from proposing substitute names in the absence of authentically 
named material which would enable me to judge of the validity of 
the proposed varieties. 
Addendum.—While this paper is passing through the press, I have 
received from Dr. von Ihering of the Museum of San Paulo, Brazil, 
a photograph and data relating to a Volute which he supposes to be 
new and which was obtained from the stomach of a fish in those 
waters off the island of St. Sebastiano. It is an Adelomelon of the 
type of A. ornata, but much more slender; elongate-fusiform, with 
two very oblique plaits and about six whorls; the spire (above the 
posterior commissure of the aperture) nearly half as long as the 
shell, which measures 220 mm., its greatest diameter about one 
third of the whole length. For this undescribed at) Dr. von 
Ihering proposes the specific name of indigesta.
