THE NAUTILUS. 1s 
“T send by this mail more of the Budimulus you ask about ; they 
are all dead shells. I could find no living ones ; and have found these 
only in Cook and Montague Counties, Texas, at the top of the Red 
River Bluff, associated with the small shell (/elicina orbiculata) 
inclosed. The large Helix inclosed (H. roemeri) was at the foot of 
Bluff in the Red River Bottom. The Bulimulus was discovered by 
myself one mile north of St. Jo, Texas, in 1888, and again at the 
lower end of Warren’s Bend, 25 miles N. W. of Gainesville, Texas, 
December 28, 1889.” 
An illustration will be given later. 
ON SOME NORTHERN PUPIDZ, WITH DESCRIPTIONS OF 
NEW SPECIES. 
BY DR. V. STERKI. 
Pupa pentodon, Say. 
Not very much is to be added to the foregoing. It may be said, 
that this species is not so generally found with such a pure glassy 
shell, as curvidens when fresh and living, but more or less opaque 
or spermaceti white. It is decidedly variable in size and also in 
shape, being shorter, and more tumid or conical, in decidedly wet 
localities. I have a specimen from Helena, Mont. (Mr. Elliott), and 
several from Ottawa, Ont. and Winnipeg, Manitoba (sent by Mr. 
Geo. W. Taylor). Those from the latter locality are long and 
slender with a very strong callus inside of the parietal wall, in which 
the lamellz are in appearance nearly buried. 
Pupa Pilsbryana n. sp. 
Among a few examples of the smaller form of “Pupa hordacea 
Gabb ” now described by Mr. Pilsbry as hordeacella from Arizona, in 
’ Mr. W. G. Mazyck’s collection, there was one specimen of an evidently 
new species, well formed and mature, and fresh although dead. 
Possibly there are more such in lots of the species mentioned above 
and sent out by Gabb. A few days ago among Pupide from Albu- 
querque I found 4 examples, although somewhat different, evidently 
being of the same species, which consequently is confirmed. [Known 
from the region of the Rio Grande del Norte, and that of the 
Colorado River, and being doubtless distinct from all the species de- 
scribed, it is to be brought to general knowledge under a new name,
