 smooth, extremities rounded, scarcely euiargiuated, 

 lip thickly varicose, columella callously ridged above 

 and below, one-plaited.

llah. New Caledonia. 



An extremely delicate species, in which the cohunella is 

 callously ridged below as well as above, the ridge being 

 continuous with the outer lip.

The Adriatic Ovuluji. Shell elongately ovate, some- 

 what pear-shaped, thin, transparent, white, back 

 transvei'sely obscurely ribbed, longitudinally minutely

Hab. Adriatic Sea. 



This very delicate transparent shell is distinguished by 

 its elongately pyriform character.

The margined Ovulum. Shell somewhat pyriforraly 

 ovate, ti'ansparent white, back transversely obscurely 

 finely ribbed, longitudinally minutely striated, lip 

 opake, thick, irregularly dentatejy serrated, colu- 

 mella callously ridged at the upper part, excavated 

 and obtusely plicated at the lo.vjr.

The excavation at the base of the columella gives more 

 than usual width to the aperture of this species.

Ovulum pyriforme. Ov. lesld pyrifomd-ovatd, soUdi-

The pear-shaped Ovulum. Shell pyriformly ovate, 

 rather solid, pinkish-white, baek smooth, extremities 

 canaliculately beaked, lip thick, columella callously 

 ridged at the upper part, rather obscurely plicated at 

 the lower.

 Amphiperas pyriformis, Adams. 



Hab. New South Wales ; Sowerby. Satanomosaki, Japan 

 (at the depth of fifty-five fathoms) ; Adams. 



The distinguishing peculiarity of this species consists 

 in its extremities being canaliculately beaked. The shell 

 is therefore more than usually constricted at the base, and 

 more pear-shaped.
