224 -NEW MELANID7E OF THE UNITED STATES. 



My cabinet and cabinet of Dr. Showalter. 

 Diam. -36, Length -76 inch. 



Remarlcs. — This is a beautiful banded species, having the two middle bands 

 more approximate. The four bands are broad and of an intense brown 5 on the 

 upper whorls a single band only is exhibited. On one specimen this band 

 reaches nearly to the apicial whorl, in the other only to the second. Its mucro- 

 nate spire and inflated body whorl reminds one of Melania conica, Say, but it may be 

 distinguished by its having a larger body whorl and a shorter spire. The aperture 

 is nearly half the length of the shell.

Remarlcs. — This is a well marked species with an unusual yellow, smooth epi- 

 dermis. There are four specimens before me, one being quite young, the others 

 mature or nearly so. One has four somewhat obscure, broad, purplish bands, better 

 defined within. The aperture is about half the length of the shell. In outline it 

 approaches Lithasia Florentiana and L. fuliginosa, both which were described by 

 me as Melanice, but it is larger, more yellow, has a higher spire and is not so 

 thickened on the columella as either of those species. 



GONIOBASIS VARIATA. PL 34, fig. 11. 



Testa lsevi, subfusiformi, crassiuscula., vel luteola vel purpurescente ; spira valde obtusa ; suturis 

 irregulariter impressis ; anfractibus senis, superne planiusculis, ultimo inflato ; apertura grandi, 

 intus vel luteola vel purpurescente ; labro acuto ; columella arcuata, incrassata, ad basim obtuse 

 angulata. 



Shell smooth, subfusiform, somewhat thick, yellowish or purplish ; spire very 

 obtuse ; sutures irregularly impressed ; whorls six, flattened above, the last inflated ; 

 aperture large, yellowish or purplish within ; outer lip sharp ; columella arcuate, 

 thickened, obtusely angular at base.
