Pleurotoma acuminata T Powerby. PI. 20, fig. 10. 



(Minei-al Conchology, II, p. 10"'.) 



Shell fusiform, acuminate, of about nine volutions ; whorls flat- 

 tened, longitudinally plicated and traversed by fine revolving lines, 

 which become crowded on the concave upper portion of the whorls, 

 and alternate on the basal portion of the body-whorl ; suture bor- 

 dered inferiorly by an elevated line, which is somewhat crenulated 

 by the sinuous lines of growth ; aperture less than one-half the 

 length of shell. 



Length, 1 inch. Cave Branch, Clarke Co., Ala. 



This Pleurotoma corresponds ver}- closely with the descriptions 

 and figures of P. acuminata as given by Sowerb}^ in the " Mineral 

 Conchology," and by Edwards in his monograph of the English 

 Eocene mollusca ( Palfeontographical Society'- Reports, 1854, p. 

 230, pi. xxvii, figs. 3a, 6, c, d), and will probably prove, on direct 

 comparison, to be referable to that species. 



PYRULA, Lamarck. 

 [Ficula, Swainson. ) 



Pyrula multangulata, n. sp. PI. 20, fig. 2. 



« 



Shell elongated, sub-claviform ; apex of spire obtuse, consist- 

 ing of three smooth volutions ; whorls about seven, covered with 

 revolving stria?, which are very fine on the upper portion and 

 shoulder of the body -whorl, but less so and attenuate on the basal 

 portion ; body-whorl occupying about three-fourths of the entire 

 shell, marked b}^ two prominent and one lesser carinse, and a 

 sino-le row of crenulations on the shoulder angulation ; the fourth 

 whorl (the first one bearing ornamentation) appears cancellated ; 

 columella curved. 



Length. 1 inch. CaA^e Branch; Wood's Bluft', Clarke Co., Ala. 



Pyrula tricostata, Deshaye?. PI. 20, fig. 6. 



(Coquilles Fossiles, ii, p. 584, Atlas, PI. 79, figs. 10 and 11.) 

 Although I have no specimen of Pyrula tricostata for direct 

 comparison, I have, nevertheless, but very little hesitation in 

 referring the Alabama form above figured to the same species, as 

 it agrees in all essential respects with the figures and descriptions 

 of that form as given by Deshayes in the Coquilles Fossiles. 

 Three unnamed specimens of a Pyrula in the Academy collection 

 from Dax, France, which I believe to be the P. clava (Oligocene?) 

 of Basterot, somewhat resemble the Alabama species, but are
