Aldrich' s original description. — ( Op. cit. ) 



It was most probably a form of this species that Aldrich char- 

 adlerized as '" Miirex engoiiatusf Con." in Bull. No. i, Geol. Surv. 

 Ala., p. 56, 1886, from Gregg's landing. I have little doubt that 

 the larger specimen herewith figured is an adult form of this 

 species. The tpye is herewith figured. See fig. 3.

Aldrich'' s original description. — "Shell acuminate, whorls ten, 

 rounded; spire high, with three embryonic whorls, the first two 

 smooth, the next showing longitudinal varices, the balance with 

 numerous (in the type nine) strong varices, which are, when 

 perfect, thin, fringing and sigmoid; six or more revolving lines 

 cut the edge of the varices into an equal number of crenulations, 

 these revolving lines being strongest at their intersecfting points; 

 aperture ovate, terminating in a narrow canal which turns 

 strongly to the left and slightly upward; outer lip sharp, thick- 

 ened and crenulated within; three slight protuberances on the 

 anterior part of the columella near the canal. 



''Locality. — Ivower bed, Woods bluff, Ala. 



"Only two specimens found. This species is more acuminate 

 and has a shorter canal than is usual in living forms. ' '
