VOLVULA. 235 



fucicola is a (posthumous) nude name, absolutely unknown except 

 for Brusina's statement that it is the B. acuminata Brug. 



Var. BREVIS Pilsbry. PI. 60, fig. 11. 



Shell regularly spindle-shaped, or forming an elongated oval 

 which is pointed above and broad below ; it is thin, almost trans- 

 parent, and glossy ; sculpture slight spiral strise at each end, and 

 very faint microscopic lines in the same direction on the interme- 

 diate space ; the strise near the apex are fewer and more remote 

 than those near the base; epidermis inconspicuous; color, clear 

 white. Mouth very long, commencing at the top in a short and 

 slightly recurved spike, and gradually widening towards the base, 

 where it is expanded and rounded ; outer lip flexuous, with a sharp 

 edge ; inner lip consisting of a mere film on the upper part and in the 

 middle, but thickened and reflected at the base, so as to give the 

 pillar the appearance of having a short fold ; pillar twisted, and 

 bending a little to the left. (Jejfr.). 



Alt. 3-75, diam. 1-87 mill. 



Northern Europe ; Mediterranean. 



This form is far stumpier than the typical V. acuminata, the 

 diameter being nearly one-half the altitude. The references to 

 Forbes and Hanley, Jeffreys (Brit. Conch.), and Adams in the 

 above synonymy, belong to this form. 



V. OXYTATA Bush. PL 26, fig. 63. 



Shell rather small, somewhat cylindrical, with a sharp, spike-like 

 apex and a tapering, rounded, anterior end, rather thin, semi-trans- 

 parent, somewhat lustrous, with four or five very fine, indistinct, 

 punctate spiral lines on each end, and very indistinct, microscopic 

 strise on the intervening surface. Aperture long, very narrow, ex- 

 panded anteriorly ; outer lip thin, following the curvature of the 

 body whorl to just below the middle where it continues in a straight 

 line and joins the inner lip in a broad curve; inner lip very thin, 

 slightly reflected anteriorly over a slight umbilical chink. Color 

 bluish-white under a pale yellow epidermis. Length of one of the 

 largest specimens 4, breadth, T5 mill. (Bush). 



East coast of the United States, from Hatteras to Cuba, 5-63 fms.
