though a doubtful species, highly imperfect, is mentioned by Dickerson 

 from the Tejon of CaUfornia. 



Type in the Wanganui Museum. 



Fusinus altus n. sp. (Plate XVI, fig. 5.) 



Shell of moderate size, narrowly fusiform. Length, 60 mm. ; width, 

 17 mm. Spire of seven whorls, gradually tapering ; each whorl strongly 

 convex, adorned with twelve broad transverse ribs which extend to the 

 anterior but not to the posterior suture : they are much stronger on th(^ 

 suture than elsewhere. About twelve strong spiral striae on each whorl, 

 but they are much stronger near the carina than elsewhere. There are 

 often much smaller striae intercalated between the larger ones. Aperture 

 not complete, but moderately wide. Outer lip with well-marked internal 

 ribs. Beak long, with spiral striation similar to that of the rest of the shell. 



This species is rather slender, but approaches more closely to F. kai- 

 paraensis than to any other. The radial ornamentation, however, is much 

 less pronounced, and the carina is much less marked. The shell is also 

 considerably narrower. 



A single specimen, not well preserved. 



Type in the Wanganui Museum. 



Latirus dubius n. sp. (Plate XVI, fig. 6.) 



Shell of moderate size, 33 mm. by 10 mm., narrowly fusiform. Spire 

 of four whorls, each of them strongly convex. Aperture incomplete, but 

 terminating in a short canal which is bent sharply upwards. Inner lip 

 wide, and extending forward beyond the columella for two-thirds of its 

 length. Columella with two well-developed folds. Outer lip wanting. 

 On each whorl a number of radial ribs — generally fourteen : these are 

 moderately high and rounded, and extend from suture to suture. On the 

 upper third of each whorl a number of fine spiral lines. On the lower two- 

 thirds of each whorl there are five strong spiral lines which are much raised 

 where they cross the radial ribs. Between the strong spirals there are a 

 number of fine spirals similar to those in the upper part of the whorl. 



One specimen only, rather imperfect. I have some hesitation in 

 following the late Mr. Suter's advice and classing this species in the genus 

 Latirus. 



Type in the Wanganui Museum. 



Belophos incertus n. sp. (Plate XV, fig. 3.) 



Shell small, shortly fusiform, 15 mm. by 9 mm. Spire of four whorls, 

 rapidly decreasing. Each whorl witli about 22 radial ridges, which are 

 slightly raised and somewhat prominent on the carina. Carina quite 

 prominent, and whorls almost shouldered ; suture impressed. About five 

 small threads between the carina and the anterior suture. Body- whorl with 

 radial ridges far less pronounced than those on the spire, and towards the 

 aperture they degenerate into growth-lines. Spiral lines numerous and 

 distinct, especially towards the end of the siphon. Aperture semi-lunar. 

 Outer lip thin but arched. Inner lip without any callosity. Columella 

 slightly bent backwards. 



The genus Belophos has not previously been recorded from New Zealand, 

 but it has been found in the Eocene of Australia. 



A single specimen, in good condition. 



Type in the Wanganui Museum.
