above, produced below into a moderately long recurved and open 

 canal, notched at the base. Outer lip flatly convex, sharp, 

 much thickened inside, and distinctly toothed. Columella 

 vertical, arcuate, with a number of tubercles at the base ; inner 

 lip rather narrow upon the pillar, extending over the parietal 

 wall, which has a well-marked plait below the suture ; the lip 

 is narrowed below, forming the inner edge of the canal. Fasciole 

 prominent, lamellate ; a narrow groove between it and the edge 

 of the canal. Operculum horny, yellowish, the nucleus apical. 



Diameter, 15 mm. ; height, 28 mm. Angle of spire, 47° to 50°. 



Type in my collection. 



Hab. — Dunedin Harbour, type frl. S.) ; Lyttelton Harbour 

 (H. S.) ; Preservation Inlet ; Auckland Islands. 



Remarks. — This species is much more solid than E. littori- 

 noides, Reeve ; the spiral bands are inconspicuous, and the 

 outer lip is not banded with brown within. When studying 

 the exhaustive descriptions and very good figures of E. fuscata, 

 Brug. ( = Bucc. antarcticum, Reeve), published by Dr. H. Strebel 

 (Zool. Jahrb., Abt. Systematik, vol. xxii, 1905, p. 611) I was 

 more than doubtful about the identity of the New Zealand 

 species, and I asked for Dr. Strebel's opinion on the subject. 

 He most courteously informed me that our species was not 

 E. antarctica, Reeve, at all, and that it seemed to him more 

 nearly allied to E. dira, Reeve, from the west coast of North 

 America. Our shell, however, in my opinion, is also quite 

 distinct from this as weh\ but nearly allied to E. vittata, litto- 

 rinoides, and striata. The four species so closely resemble one 

 another that it is not always easy to separate them, their vari- 

 ability being so great. I have much pleasure in uniting the 

 name of the distinguished conchologist, Dr. Hermann Strebel, 

 with the species. 



20. Tritonidea (Cantharus) fuscozonatus, n. sp. Plate XXX, 



fig. 5. 

 Shell ovato-fusiform, solid, spirally ridged and axially broadly 

 costate. Sculpture consisting of regular spiral lirao of sub- 

 equal strength, the interstices with 1 or several fine spiral threads, 

 the lira? more prominent and further apart on the base ; axial 

 ornamentation formed by rather distant, elevated, and broadly 

 rounded axial costa>, about 15 on a whorl, the spirals passing 

 over them ; they are getting obsolete on the base. Colour 

 fulvous, the spiral riblets purple, sometimes a purple band above 

 the suture and a second below the periphery of the body-whorl 

 are present, also longitudinal streaks of light-brown; aperture 

 whitish within. Spire conical, turrcted, of the same height as 

 the aperture with canal ; outlines straight. Protoconch conical,
