ANCULOTUS.— Plate VI. 



Species 50. (Fig. 50 b, Mus. Anthony.) 

 Anculotus TiENIATUS. Aiic. testa ovalo-conoided,fulves- 

 cente-olivaced, fasciis interrupts virente-nigris cingu- 

 latd, anfractibus declivi-convexis, Imvibus ; aperturd 

 pyriformi-ovatd. 

 The filleted Anculotus. Shell ovately conoid, ful- 

 vous-olive, encircled with interrupted bands of green 

 and black, whorls slopingly convex, smooth ; aperture 

 pyriformly ovate. 

 Conrad, New Freshwater Shells, p. 63. 

 Hab. Alabama, United States. 



On the authority of Mr. Anthony, who possesses a spe- 

 cimen named by Conrad himself, I am able to give this 

 as A. taniatus instead of the shell represented at Plate II. 

 Fig. 15, which appears to be a banded A. preerosus or 

 tintinnabulum. It is a strong peculiarity of A. tceniatus 

 that the bands are interrupted, while the shell is more 

 conical. 



Species 51. (Mus. Anthony.) 



Anculotus angulatus. Anc. testa subglobosd, fulves- 

 cente-olivaced, fasciis nigro-virentibus cingulatd, spird 

 brevi, aufractibus rotundatis, angulate bicarinatis ; 

 aperturd ovatd, columella excavato-incurvd. 



The angled Anculotus. Shell subglobose, fulvous- 

 olive, encircled with interrupted dark-green bands, 

 spire short, whorls rounded, angularly two-keeled ; 

 aperture ovate, columella excavately incurved. 



Conrad, Freshwater Shells. 



Hab. Alabama, United States. 



The whorls of this species obtain a slight angled ap- 



pearance from the presence of two very faintly developed 

 distant keels. 



Species 52. (Mus. Anthony.) 



Anculotus zebra. Anc. testa subglobosd, fulvd, nigro- 

 virente interrupts strigatd, spird brevi, aufractibus 

 superne obtuse contractis, delude convexis, lavibus ; 

 aperturd ovatd, subampld. 



The zebra-like Anculotus. Shell subglobose, fulvous, 

 interruptedly streaked with dark-green, spire short, 

 whorls obtusely contracted at the upper part, then 

 convex, smooth ; aperture ovate, rather large. 



Anthony, Pro. Acad. Nat. Sci. Philadelphia, I860, p. 69. 



Hab. Alabama, United States. 



The dark-green painting of this species is not disposed 

 in spiral bands, but in interrupted longitudinal streaks. 



Species 53. (Mus. Anthony.) 



Anculotus affinis. Anc. testa conico-ovatd, sordide 

 olivaced, aufractibus declivi-convexis, lavibus, ultimo 

 medio subobsolete carinato ; aperturd rotuudato-ovatd, 

 columella calloso-dentatd. 



The allied Anculotus. Shell conically ovate, dirty- 

 olive, whorls slopingly convex, smooth, the last 

 faintly keeled round the middle ; aperture rotundately 

 ovate, columella callously toothed. 



Haldeman, MS. in Mus. Anthony. 



Hab. Southern United States. 



Of a different type from any of the preceding species, 

 with the columella abruptly toothed.
