4. C. ACICULA (Miiller). PI. 1, figs. 1, 2, 5-8. 



"Shell turreted and slender, transparent, very thin, highly 

 polished and iridescent, ivory-white, with a yellowish tinge on 

 the upper part in fresh specimens (owing to the color of the 

 liver), perfectly smooth and polished when examined with a 

 lens of ordinary power, except a few faint and irregular wrinkles 

 in the lines of growth, but under a microscope exhibiting deli- 

 cate and close-set spiral stride. Periphery rounded. Epidermis 

 exceedingly thin and forming a mere film. Whorls 5^, not 

 convex, but compressed and drawn out, rapidly increasing in 

 size; the last occupying about one-half of the shell. Spire very 

 obtuse and rounded at the point. Suture moderately deep and 

 oblique, apparently margined on the under side by reason of 

 the upper part of the succeeding whorl being seen through the 

 pellucid shell; mouth oblong, contracted by the penultimate 

 whorl, narrowing above into an acute angle, slightly widened 

 and rounded below, but interrupted by a deep notch at the base 

 of the pillar lip." Outer lip thin and flexuous. Pillar lip 

 thick and curved. Inner lip consisting of a slight deposit of 

 shelly matter, which is spread on the pillar. Length 0.175, 

 breadth 0.04 inch (Jeffreys').
