Semifusus {Maycria). Since the aperture is missing in the Pondo- 

 land specimen the generic position of the species cannot be satisfac- 

 torily determined. That species also shows some resemblance to 

 Serrifusus dakotensis, Meek and Hayden, var. Vancouver ensis, Whit- 

 eaves,"'' of which the generic position is likewise uncertain.! Whether 

 the two forms are really related or not cannot be determined at 

 present. 



A specimen which was recorded by Griesbach as Lagena nodulosa, 

 Stoliczka, resembles the example referred to above, but possesses 

 a shorter spire (Plate XL., fi.g. 6).

 Genus VOLUTILITHES, Swainson. 



VOLUTILITHES, Sp. 



Plate XL., fig. 7. 

 A single imperfect specimen of a large Volutid is provisionally 

 referred to the genus Volutilithes. The spire is short and conical. 

 The ornamentation consists of a few strong, transverse ridges, which 

 are prominent at the angle of the whorl but soon decrease in size 

 anteriorly. There are also indications of spiral ribs. The aperture 

 is broad and canaliculate posteriorly ; the outer lip is toothed. On 

 the columella there are four oblique folds, of which the two posterior 

 are shghtly stronger than the two anterior. A very small fold is 

 present between the first and second main folds, and another 

 between the third and fourth.
