THE NAUTILUS. LOT 
the courtesy of my friend, Dr. W. H. Dall, for the following deserip- 
tion from the National Museum examples: 
Shell of an oval form, considerab y flattened and with about two and 
a half whorls; color, dark brick red, with occasional mottlings of pale 
bluish green; holes, four in the young to six in the adult; sculpture, 
of fine, somewhat irregular spiral threads, crossed by fine, close, slightly 
elevated, sharp, concentric lamellee, and a few small obscure wavelets 
which radiate obliquely from the apex ;. nacre rather pale, with pink 
and pale green reflections, but much less deep in color than the typ- 
ical fulgens Lon., 100; lat., 68; alt., 17 mm. 
This variety differs from the type in its more elongate and flattened 
form, its constantly finer, spiral threading and its paler nacre. The 
concentrie lamellation is sometimes undeveloped on the young shells. 
It has the same number of boles as the type. 
This varietal form may be regarded as the extreme northerly expres- 
sion of Hf, fulgens; the latter, if my memory is not at fault, has not 
heretofore been credited to any part of the coast north of Point Con- 
cepcion ; from that point to Gualalla is an immense jump, about 320 
nautical miles.

GENERAL NOTES. 
A New Genus or Hetices.—Upon dissecting specimens of Poly- 
gyva miorhyssa Dall, recently, Prof. Cockerell noticed several important 
points of divergence in the genitalia as compared with what has been 
been observed in Polygyra, and sent fresh material to Prof. Pilsbry, 
stating that a new group seemed to be indicated, and requesting fur- 
ther examination This resulted in the confirmation of the features 
first noticed and the discovery of others, indicating a new generic 
group, which may be called Ashmunella, in honor of Rev. EK. H 
Ashmun, whose researches in New Mexico and Arizona have added 
materially to our knowledge of the mollusk fauna of those regions. 
The type is P. mtorhyssa Dall. An illustrated account of Ashmun- 
e/la will appear in the Proceedings of the Academy of Natural Sci- 
ences of Philadelphia. eA. Po & ED, Ay C 
MELAMPUS FLORIDANUS SHUTTL. 
In August; 1894, I collected 
some Melampus on Chambers’ farm, Queen Anne county, opposite 
Chestertown, Md. They were put in the collection of the Academy 
under the name, I. I/neatus Say, but on examination they prove to be 
M. floridanus, Shuttl. May not other collections have this Floridian 
species from northern localities ? K. G. VANATTA.
