Helix minuta, True (Froc. Essex lust., ii, pt. 2, 193, Salem, Mass., 1860). Shell 

 minute, rouuded conical, smooth, apex obtuse ; epidermis of a uniform red- 

 dish horn-color ; whorls 4, rounded above and below, with a well-defiued 

 suture; aperture rounded, lip simple and thin; umbilicus broad and deep.

Helix EoweJli, Newcomb (see L. & Fr.-W. Sh., i, 185), has been accredited to Arizona, 

 but not on uudoubted authority. I have not included here the Lower Cal- 

 ifornia species, for which see ji. 22. 



Helix radiata, Lister (Europe aud Virgiuia), of Bosc, Hist., iv, 32, appears to be H. 

 alternala, as reference is giveu to Lister's figure of that species. 



Helix irivolris, Eaton (Zool. Text-Book, 194), = Planoriis. 



Helix hicarinaUis {id., 194) ■= Planoriis. 

 ' Helix pai-vus (id., 19^):= Planoriis. 



Helix catascopius (id., 195) = Limnwa.

Helix suicaritiatus {id., 195) = Lioplax.

Helix decisa {id., 196) ^^^Melantlio. 



Helix CumierJandicus, Lea, of Wheatley's Cat. U. S., 18, is the same, I presume, 

 as Patula Cumierlandiana. 



Helix immitissima. Lea, of the same. p. 19, := H. mivutissimaf 



Helix pallida, Say, of same, =fi. palliata? 



Helix depicta, Grateloup, Soc. Lin. Bordeaux, xi, 399, pi. i, fig. 12 (1839). Shell 

 subglobose, conic, imperforate, thin, white, very delicately striate orna- 

 mented with varied lines aud interrupted bands ; lip simple, acute. 



This pretty shell has some points of resemblance with Helix pisana, Miill., 

 but is smaller and not umbilicated. The internal edge of the right lip is 

 white instead of rose. The upper surface is covered with numerous yellowish- 

 brown bands, more or less deep, interrupted by oblique lines of same color. 

 Five whorls. Height, ll'"'"; diameter, 15°"".
