72 TIIK NAUTILUS. 



States specie;*, including a number of s])ecies not contained in the 

 latest monographs. The geographical range of each form is given, 

 and the whole prefaced by a brief discussion of recent or original 

 changes in nomenclature. Collectors of American shells will find 

 the list a convenient one for checking their collections and their 

 desiderata when exchanging. 



Veber die Beziehung;ex einiger europdlscher und nordameri- 

 kanischer Fupiden, by Dr. V. Sterki. (In Nachrichtsblatt d. 

 deutchen Mai. Gesell., Juli-Aug., 1889.) Dr. Sterki discusses the 

 Pupre common to America and Europe in this valuable paper. 

 Species immediately allied to P. musconim are P. blandi (doubtfully 

 distinct), and P. sterri Voith ; the last seem to the writer to be also 

 a form of muscorum. The species is a mountain form, described 

 from Bavaria. Vertigo simplex and P. alticolu are considered syn- 

 onvms of P. edentula Drap. The examination of the Vertigo species^ 

 Dr. Sterki says " hat mich viel Zeit, Miihe und ' Augenmorderei ' 

 gekostet ;" and it is no wonder, as anybody who has been so rash as 

 to trouble themselves with those ridiculously little creatures will 

 bear testimony. The question of the identity of V. antivertigo Dr. 

 and ovata Say, is discussed ; and finally the new subgenus AugustiUa 

 is proposed. The principal characters are the narrowing of the last 

 whorl, peculiar constriction behind the peristome, the longitudinal 

 position of the columellar fold, and the long, narrow, high fold,, 

 arising deep in the thi'oat, and in venetzii uniting with the upper, 

 in milium with the lower palatal fold. It contains only the two- 

 species named. — P. 



Notes on some Indian Territory Shells, by Charles Torrey 

 Simpson. An interesting paper, adding considerable to our know- 

 ledge of the distribution of the shells of this region. H. ( Triodopsis} 

 conei Wetherby, formerly known from Eastern Texas, was found in 

 the Territory. A form of H. (Polygyra) Jackso)ii with elevated 

 deltoid parietal tooth is described as var. deltoidea. H. (3Iesodon) 

 Kioimeiisis, a form intermediate between thyroides and sayii is de- 

 scribed as new, and the rare Helicodisciis ftmbriatiis is reported from 

 near Fort Gibson. The shells described by Mr. Simpson under the 

 name Zonites capsella. are quite distinct from that species, as I have 

 satisfied myself by careful comparisons. It may be called Z. Simp- 

 soni, in honor of the finder. Mr. Simpson's remarks on the 

 BnlimnlHs dealbatus, seJiiedeamis and alfernatus should direct the 

 attention of collectors to these forms, which are lielieved by Mr. S. 

 to be varieties of a single variable species.
