Anthony, Pro. Acad. Nat. Sci. Philadelphia, 1860, p. 59. 

 Hab. Alabama, United States. 



A smooth, bright yellowish-olive shell, of somewhat 

 rude growth. 



Species 452. (Mus. Anthony.) 



Melania Vanuxemiana. Mel. testa subcylindraceo- 

 ovutd, virente-olivaced, undique plus minus fasciati, 

 anfractibus quatuor ad quinque, spiraliter Uratis, lon-

 longo-ovatd, ad basin effusa. 



Vanuxem's Melania. Shell somewhat cylindrically 

 ovate, greenish-olive, more or less banded through- 

 out, whorls four to five, spirally ridged, longitudi- 

 nally faintly plicately noduled ; aperture oblong- 

 ovate, effused at the base. 



Lea, MS. in Mus. Cuming. ,U V 



Hub. Alabama, United .States. 



A solid, cylindrically-ovate shell, brightly banded and 



ridged across, the ridges being faintly noduled by obscure 



lonsritudinal folds. 



Fig. 543. (Mus. Anthony.) 

 Mr. Anthony suggests that this might be published as 

 a new species, with the name M. fragosa ; but I incline 

 to think, on further consideration, that it is a variety of 

 the preceding, in which the central keels are more strongly 

 developed, imparting a more angular outline to the shell. 



ffavescente-oHvaced, anfractibus septem ad octo, an- 

 gustis, convexis, arcuato-striatis ; aperturd anguste 

 ovatd, labro sinuato, columella brevi, ad basin con- 

 spicue contort o-canaliculatd. 



The solid Melania. Shell obtusely pyramidal, solid, 

 yellowish-olive, whorls seven to eight, narrow, con- 

 vex, arcuately striated ; aperture narrowly ovate, lip 

 sinuated, columella short, conspicuously twistedly 

 clianiielled at the base. 



Lea, Trans. Araer. Phil. Soc. vol. x. pi. 9. f. 27. 



Hab. Tennessee, United States. 



A pyramidally conoid shell, with the whorls unusually 

 closely convoluted, conspicuously twisted at the base into 

 a short channel. 



Species 454. (Mus. Anthony.) 

 Melania solida. Mel. testa obtuse pyramidali, solidd, 



Species 455. (Mus. Anthony.) 



Melania olivula. Mel. testa conico-ovatd, so/idiuscu/d. 

 olivaceo-brunned, pallidissime fasciald, anfractihus 

 paucis, cgliudraceo-convexis, lavibus vel obscure spi- 

 raliter Uratis ; aperturd ovatd, parviusculd, ad basin 

 vix effusa. 



The little olive Melania. Shell conically ovate, ra- 

 ther solid, olive-brown, very faintly banded, whorls 

 few, cylindrically convex, smooth or obscurely spirally 

 ridged ; aperture ovate, rather small, scarcely effused 

 at the base. 



Conrad, Amer. Jouni. Sci. p. 25. pi. 1. f. 13. 



Hab. Alabama, United States. 



This, and not the shell represented at Plate XLIIL. 

 Fig. 309, is the true M. olixula of Conrad. It is usually 

 much eroded towards the apex.
