set ; aperture long and narrow, the border of the posterior 

 notch reaching beyond the suture; outer lip reflexed and flat- 

 tened, faintly striated anteriorl}^ ; inner callus strong posterior- 

 ly, with two moderate plaits very angular to each other. 



This species is of medium size and is peculiar in having 

 the longest aperture of any species known in our Eocene. The 

 surface is much more finely marked than other forms. It ap- 

 proaches R. trapaqiiara Harris, but differs, as above stated, from 

 it. It is much closer to R. dalli Clark, and while the plaits on 

 the inner lip are more angular to each other, and the aperture a 

 little longer, yet other specimens may be found to unite the two 

 forms. 



Locality. — Alabama: Matthews' Landing. 



Ringicula butleriana var. lignitifera n. var., pi. 2, fig. 9. 



Shell medium, rather wide; inner lip striated within ; callus 

 strong, bearing posteriorly a small eredl tooth, anteriorly with 

 two strong plaits. 



This form is placed here provisionally; more examples may 

 justify its eredlion into a new species. None of many examples 

 of R. butleriana Aid. show the striated outer lip. A single ex- 

 ample resembling this variety was obtained at Nanafalia, Ala. 



Locality. — Alabama: Bell's Landing (upper) bed. 



PHILINE. 



Philine alabamensis n. sp., Pl. ^^ fig. 6. 



Shell oval; whorls about one and a half, smooth and rudi- 

 mentary at the apex, elsewhere covered with fine spiral lines 

 which are finely zig-zag; outer whorl rising above the apex, con- 

 stri(5led above, expanding rapidly below. 



This is an exceedingly thin and delicate shell, the first of the 

 genus to be found in our Eocene. 



Locality. — Alabama: Wood's Bluff horizon at Chocftaw Cor- 

 ner. 



ACT^.ON. 



Actseon cossmanni n. sp., Pl. 2, fig. 5. 



Shell slender; shining spire bluntly pointed; whorls seven, 

 body whorl over half the length of the shell; suture impressed; 

 surface ornamented with fine, close-set, impressed, spiral lines;
