C. INFLATUM (Maynard). PI. 37, figs. 52, 53. 



" Size medium; shell heavy; striations are absent. Whorls 10. 

 Teeth, two, and short. Examined 25 specimens. Form of shell 

 cylindrical, with the second [penult.] and third [antepenult.] whorls 

 the largest in diameter, the first [last] and fourth [from the base] 

 are a little smaller, the fifth [from the base] is considerably smaller 

 than the fourth, and from this the shell slopes rapidly to a blunt, 

 rounded, nearly hemispherical apex, forming a wide angle of nearly 

 90 degrees. The surface is polished but is slightly furrowed with 

 lines of growth, which are much less prominent on the lower [ear- 

 lier] whorls. The sutures are shallow, and the whorls between 

 them are slightly bulging. 



" Aperture of medium size but open, and measures considerably 

 more just within than at the entrance. Lower [parietal] tooth very 

 slightly developed and is raised by gradual elevation from the sur- 

 rounding surface. It is about .10 in. long. The upper [columellar] 

 is situated considerably above, is about as prominent, but is more 

 conspicuous within. Margin not produced forward as far as the 

 diameter of the shell, is inclined slightly backward and a little to 

 the right ; it is not thickened, and the outer portion is produced into 

 a thin but not prominent edge which is not rolled downward. The 

 frontal bar is not prominent, being interrupted in the middle. 



" Color of shell externally white, conspicuously striped with yellow- 

 ish-brown that becomes nearly yellow on the lower whorl, and which 

 occupies the last two, wholly excluding the white. The margin, 

 frontal bar, and teeth are yellowish, and on the lower wall, within 

 the aperture, are purplish-brown stripes that merge into the universal 

 purplish brown of the interior." {Maynard.} 



Length 22.5, diam. 8.75 mill.

Strophia inflata MAYN., Contrib. to Sci., i, p. 126, f. 30, pi. 7, 

 f. 21 (October, 1889). 



Apparently well marked by the heavy, smooth, copiously striped 

 shell and the inflated spire, the penultimate whorl being wider than 

 the last, the next earlier whorl frequently wider than the penult. 

 Types are in coll. Maynard and Boston Society of Natural History. 

 Specimens labelled JExuma are in the collection of the Smithsonian 

 Institution, according to Maynard (Contrib., 5, p. 133).
