TURRITELLA, Lam. 



Turritella Tippana. Journ. Acad., Vol. 3, p. 333. 



Dr. Spillman has forwarded fine specimens of Turritella, which may be varieties 

 of this species. One is four inches long, and has on each of the larger whirls of spire 

 four prominent, revolving lines, the two upper pair smaller and more approximate 

 than the lower pair ; the wide interval between the two pair of ribs is finely striated 

 with unequal lines. Another specimen two inches long is similarly striated with fine 

 lines, whilst the large, revolving lines are six in number on each whirl and much less 

 prominent than in the preceding species. These lines though unequally are yet more 

 regularly arranged than in the variety above described. 



Turritella trilira. Turrited ; whirls with three equidistant, very acute, promi- 

 nent ribs ; revolving lines microscopic, closely arranged. 

 Length 2i ? inches.

DAPHNELLA? Hinds. 



Daphnella ? Eufaulensis. Fusiform, whirls slightly convex ribs, rather distant,

 longer than the aperture and beak, and consisting of about ten whirls. 



Length 1% inches; width i inch.

 impressed at suture, ribs numerous ; revolving lines minute, rugose, raised and very 

 closely arranged ; spire nearly or quite equal in length to beak and aperture ; columella
