Cheilea in its rights? There was no diagnosis given with Hum- 

 phrey's names, only lists of species. Passing them over, we find 

 Lamarck eliminated Crepidula and Galyptrcea with proper diag- 

 noses, though his CaJyptrcea comprised species of two genera. He 

 left behind a single species, which, if Lamarck had been the first 

 to divide the genus, would have kept the name Cheilea. On the 

 other hand, he included in his genus Ccdyptrcea, a species he should 

 have omitted. The first was named Septaria bv Ferussac in 1807, 

 and this left only one genus included in the original Cheilea un- 

 named. This was called Mitrularia by Schumacher in 1817, but 

 in our opinion this name must be rejected for that, of Modeer, 

 which should be adopted for the group represented by the Patella 

 equestris of Linnaeus.

MOLLUSCA OF THE GREAT SMOKY MOUNTAINS. By Henry A. 

 Pilsbry. Proc. Acad. Nat. Sci., Phila., 1900, pp. 110-150. This 

 is the most interesting faunal list the writer has seen in a long while. 

 It results from the explorations of Messrs. Pilsbry, Ferriss, Bryant 

 Walker, Clapp and Sargent in July and August, 1899, along the 

 Tennessee-North Carolina boundary, among the valleys and on the 

 peaks of the Great Smoky Mountains. In all, fifty-six species of 

 terrestrial mollusca were obtained, among which Gastrodonta ivalkeri, 

 Punctum blandianum, and several varieties of different species are 

 described as new. Two things are especially noticeable, one the 

 abundance of endemic species and varieties, the other the absence of 

 many species which one is accustomed to regard as universally dis- 

 tributed in the mountains of this continent. Of course more of the 

 latter may yet be found, but it cannot be purely accidental that the 

 party came upon no Vitrina, no Pupa, only one Vertigo, and that 

 very rare, only one Bifidaria, also rare, and no Vallonia! In some 

 cases widely -distributed species are represented by segregates which 

 have attained specific rank ; thus in place of Vitrea indent ata there 

 is an abundance of V. carolinensis of a small type (var. wetherlyi, 

 Ckll. ined.) intermediate between indentata and carolinensis proper, 

 the exact locality of which is unfortunately unknown. In the case
