Shell rather solid, usually elongated, very glossy and of a de- 

 cidedly porcellanous texture; whorls generally somewhat flattened; 

 sutures impressed; color ivory white to straw colored with a broad, 

 faint yellow band above the periphery and a wide, faint yellow 

 basal band; axial region white.

Key West; Sugarloaf Key; Big Pine Key; No Name Key; Litttle 

 Pine Key. Probably once an inhabitant of all the drier islands of 

 the lower chain of keys. Some of the specimens received from 

 residents of these islands are not much elongated.

1912. Liguiis solidus solidtilus Pilsbry. Jouru. Acad. Nat. Sci. Philadelphia, 

 p. 463, pi. 37, fig. 2a. 



Shell rather thin, slightly to moderately elongated; whorls more 

 rounded than in solidus j color pattern generally an ivory white 

 ground with two narrow faint yellow bands at the periphery, one at 

 the suture and one on the base, sometimes with a few dark, spiral 

 lines on the last whorl ; whole surface glossy and porcellanous, axial 

 region white. 



Length 60, diameter 28 mm. ; length 60, diameter 30 mm. 



Entire chain of the Lower Florida Keys. 



I collected specimens on Stock Island which are more richly col- 

 ored back of the aperture than on the rest of the shell, and some 

 have from two to eight narrow spiral lines on the last whorl. I 

 have in my collection a set of specimens received from an exchange 

 and labeled " Monroe County, Fla.," one of which has no real dis- 

 tinction of banding but is nearly uniform yellowish on the last 

 whorl, and another has faint, broad, yellow bands that break up 

 into blotches.
