THE NAUTILUS. 123 



" I send by this mail more of the Bulimulus 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 (He/icina orhiculata) 

 inclosed. The large Helix inclosed (i?. roemeri) was at the foot of 

 Bluff in the Red River Bottom. The Bulimulus Avas 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 PUPID^, WITH DESCRIPTIONS OF 

 NEW SPECIES. 



BY DE. V. STERKI. 



Pupa pentodon, Say. 



Not very much is to Toe 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 lamellae 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 Ao?-cZeace/^ff from Arizona, in 

 Mr. W. G. Mazyck's collection, there wag 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 Pupidse 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,
