Patella geometrica n. sp. 



Shell large and heavy, up to 50 mm. or more in length, suborbi- 

 cular. Apex elevated, well forward. Surface ornamented by about 

 twenty broad, strong, radial ribs, which are much wider than the 

 interspaces. Radial ribs crossed by numerous, prominent, narrow, 

 sometimes leafy, transverse ridges. 



Locality : Sooke beds, Vancouver Island. 



Turritella diversilineata n. sp. 



Shell medium size. The imperfect type specimen shows seven 

 flattened whorls, which are strongly bevelled below. Flattened 

 sides ornamented by five revolving ribs of which the lowest, stand- 

 ing on the angle of the whorl, is much stronger than the others. On 

 some of the whorls there are indications of revolving sculpture on 

 the bevelled surface between the lowest rib and the suture. 



Locality : Carmanah Point, Vancouver Island. 



Nassa Newcombei n. sp. 



Shell between 25 and 30 mm. in length. Whorls five, with a 

 well marked shoulder, ornamented by numerous longitudinal and 

 transverse ribs which give the middle portion of the whorls a tessel- 

 ated appearance. The upper revolving rib, which forms the angle 

 of the shoulder, is stronger than the others and is usually separated 

 from them by a distinct groove. On the last whorl the transverse 

 ribs (about 25) are dominant on the upper portion, excepting the 

 shoulder, and are latticed by the less conspicuous revolving sculpt- 

 ure. On the lower portion of the whorl the transverse ribs dis- 

 appear, leaving the well-defined revolving ribs uninterrupted. 



Bullia buccinoides n. sp. 



Shell ovate, whorls five. Spire short. Suture partially or en- 

 tirely covered. Aperture with strong anterior notch. Outer lip 

 thin, sharp ; inner lip with broad callus. Length 25-30 mm.
