THE NAUTILUS. 65 
above named, in the usual procession of synonyms. On the coast of 
California we find three species: C. exogyra Conr., C. pellucida Sby., 
and C. spinosa Sby., all of the foregoing having been collected by 
me personally, without going outside of Uncle Sam’s farm. 
Since writing the above, the September Nauti_us has come to 
hand. From page 57 I quote “ Family Ungulinide. Not repre- 
sented on our shores.” If, by “our shores,’ he means Rhode Island, 
strictly and literally, he may be right, but if “our shores” means 
the North American Continent or the coasts of the United States, 
he is again in error, for the said family includes, among other genera, 
Cryptodon Turton, Diplodonta of Brown (—=Mysia Leach), ete., and 
some authors include Teldimya in the same family. Several species 
of Cryptodon inhabit the waters of the Atlantic coast from the Arc- 
tic Sea to Cape Florida, at various depths from six to nearly one 
thousand fathoms. Tellimya is represented by three species from 
the Arctic Seato Hatteras and one of these, 7. elevata Stimpson, has 
been collected from two fathoms depth, coast of Maine. Diplodonta 
furnishes examples of three or four species on the west coast of N. 
America, one, perhaps two, of which, have been collected by my own 
hands. Felania, another group of the Ungulinide, furnishes two or 
three species on the Pacific side to justify this criticism. Cryptodon 
(which Mr. Carpenter mentions incidentally in connection with the 
Lucinide) and Tellimya, it may be pleaded, have only quite recently 
been included in the Ungulinide; this can not be said of the groups 
Diplodonta and Felania. 
Further on (page 59) may be seen “ Family Crassatellide, not 
represented in North America.” Now Dall has described a Cras- 
satella, C. floridana, from the Gulf of Mexico west of the Florida 
coast (30 fms.), and said family is further represented by Eriphyla 
lunulata Conrad and variety parva C. B. Ad., both of which range 
from Cape Cod to Barbadoes, in from three to about three hundred 
fathoms. It may again be pleaded perhaps with reason, that a part 
of these latter facts have but very recently been made known. 
The occurrence of Crassatella on the West coast of North Amer- 
ica should have been known to him, for C. gibbosa Sby. appears in 
Philip Carpenter’s Check List of West Coast Shells (Smithsonian 
Mise. Pub., June, 1860), an easily accessible publication ; as will be 
seen by the date issued twenty-nine years ago. 
Again, while highly appreciating the convenience and value of 
authentic local faunal lists, in Mr. Carpenter’s, I do not perceive the
