DAPnNELLA. 63 



tumid ; whorls five in number, convex ; suture slightly canaliculate 

 and bordered by a shallow excavation. Surface covered by spiral 

 striaj, the penultimate whorl carrying six prominent striations, 

 between each of which are three or four minor ones. Growth-lines 

 regular, producing a species of cancellation, the points of inter- 

 section of the larger with the revolving striae being crowned by 

 a small tubercle. These groAvth-lines, also, are of two orders, 

 three or four minor ones being situated between the more prominent 

 of them. Aperture broad, rounded posteriorly and truncated 

 anteriorly ; outer margin thin, curved, the sinus being marked 

 by a mere sinuosity in the neighbourhood of the suture; columella 

 excavated. 



This species does not appear to have been described before, 

 though figured by Professor Tate, as above indicated. It may 

 be readily distinguished from the two species of Laplmella already 

 described, by the granulated aspect of the whorls, as seen under 

 a lens, by the comparatively shallow excavation bordering the 

 suture, and by the special character of the sinus. 



Dimensions. — Length 18 mm.; breadth 9 mm.; length of 

 aperture 9 mm. 



Form, and Loc. — Eocene : Muddy Creek, Victoria.

Shell cominelliform, body-whorl longer than the spire ; whorls 

 convex, six in number, finely spirally striated ; aperture ovato- 

 elongate, wide anteriorly; outer margin sinuous, but there is no 

 sinus properly so-called, reflected ; columellar margin covered 

 by a leaf-like expansion of smooth shell enamel, which is 

 continuous with the outer margin, near the suture is a small 

 callosity ; columella twisted ; canal short, recurved. 



Dimensions. — Length 20 mm. ; breadth 9 mm. ; length of 

 aperture 10 mm. 



Form, and Loc. — Pliocene : Shakespeare Cliff, Wanganui, New 

 Zealand.
