ANCULOTUS.— Plate III. 



Species 23. (Fig. a, 5, Mus. Cuming.) 



Anculotus smakagdinus. Anc. testa, ovalo-turhinatd, 

 interdum solidiusculd, vivide viridi, spira tumido-ex- 

 sertd, anfractibus declivi-convexis, Icevigatis, superue 

 triliratis, liris oblongo-granatis, aperturd ovatd, colu- 

 mella late callosd. 



The emerald-green Anculotus. Shell qvately tur- 

 binated, sometimes rather solid, bright-green, spire 

 tumidly exserted, whorls slopingly convex, smooth, 

 encircled round the upper part with three ridges, 

 ridges oblong-granuled, aperture ovate, columella 

 broadly callous. 



Hah. Alabama. 



This species has been confounded by Haldeman with 

 the preceding. It is of a peculiar bright-green colour, not 

 plicated from the sutures, but encircled with three spiral 

 ridges, swollen with transversely oblong grains, and there 

 is no purple stain upon the columella. 



Species 24. (Mus. Cuming.) 



Anculotus ornatus. Anc. testa conoideo-iurbinatd, fla- 

 vescente-oHcaced, semipellucidd, viridi quinquefasciatd, 

 anfractibm lavibus, superue declivi-convexis, deinde 

 subventricosis, aperturd ovatd, columella tenue callosd. 



The adorned Anculotus. Shell conoidly turbinated, 

 yellowish-olive, semitransparent, encircled with five 

 green bands, whorls smooth, slopingly convex round 

 the upper part, then somewhat ventricose, aperture 

 ovate, columella thinly callous. 

 ' Anthony, Pro. Acad. Nat. Sci. Philadelphia, 1860, p. 67. 



Hah. North Carolina, United States. 



A symmetrically turbinated shell, of rather light semi- 

 transparent substance, neatly banded throughout. 



Species 25. (Mus. Cuming.) 



Anculotus bit^niatus. Anc. testa ci/lindraceo-oblongd, 

 ad basin subattenuatd, fiavescenle-olivaced, purpurea 

 bi-trifasciatd, spira producld, anfractibm plano-con- 

 vexis, lavibus, aperturd oblongd, columella ad basin 

 contorto-reflexd. 



The double-filleted Anculotus. Shell cylindrically 

 oblong, somewhat attenuated at the base, yellowish- 

 olive, two- or three-banded with purple, spire pro- 

 duced, whorls flatly convex, smooth, aperture oblong, 

 columella twistedly reflected at the base. 



Melania bitceniata, Conrad. 



Hab. Tennessee, United States. 



There is a slight departure from the Anculotus type in 

 this cylindrical species, the columella being twistedly re- 

 flected at the base. 



Species 26. (Mus. Cuming.) 



Anculotus suualidus. Anc. testa ovatd vel globosd, 

 solidd, flavescente-olivaced, viridi obscure fasciatd, 

 spira brevi, obtusd, anfractibus convexo-tumidis, obso- 

 lete spiraliter liratis, aperturd luuari-rotundatd, colu- 

 mella late callosd. 

 The squalid Anculotus. Shell ovate or globose, 

 solid, yellowish-olive, obscurely banded with green, 

 spire short, obtuse, whorls convexly tumid, obsoletely 

 spirally ridged, aperture lunar-rounded, columella 

 broadly callous. 

 Lea, Trans. Amer. Phil. Soc. vol. x. pi. 9. f. 50. 

 Hab. Alabama, United States. 



This shell is very unlike the figure above referred to, 

 but it has been sent to Mr. Cuming as an authentic spe- 

 cimen of A. squalida, and Mr. Lea describes the species 

 as being peculiarly variable.
