the body-whorl but moderately ventricose. Suture compressed and 

 wrinkled. Outer Up as in the species. Columelln with 4 to 6 plaits, 

 5 being the usual number. 



Diameter, 51 mm. ; height. 147mm. (type). Diameter, 60 mm. ; 

 height. 170 mm. (large specimen. 7 whorls). Diameter, 42mm.; height, 

 93 mm. (small specimen, 6 whorls). 



Hab. Found together with the species, but it is a much rarer 

 shell. Also found at the Kermadec Islands. The type is from the 

 Bay of Islands. 



Fossil in the Pliocene, Miocene, and Oligocene. 



2. Fulguraria depressa, Suter, 1908. Plate 48, fig. 7- 



Fulguran'a (Alcithoe) depressa, Suter, P. Mai. S., viii, 1908, 182, pi. 7, f. 11. 



Shell moderately large, ovate, solid, with a short spire and large 

 aperture, the last two or three whorls with nodules on the angle of 

 the shoulder, with a few brown zigzag lines. 8rn//>lnre : The pen- 

 ultimate whorl with a row of distant roundish nodules above the 

 suture, the body-whorl with a row of elongated prominent nodules 

 on the angle of the shoulder, their number being about 8 to 10. Colour 

 yellowish- white, with a few longitudinal fulvous zigzag bands, indis- 

 tinctly arranged into 3 spiral bands on the body-whorl and a fourth 

 above the fascicle, outer lip with a few brown spots. Spin- low, 

 conoidal, its height about one-third that of the aperture. Protocottch 

 much worn and the nucleus lost. Whorls about 7, the last very large, 

 the upper whorls lightly convex, the last two broadly shouldered, the 

 slope flattish, body-whorl flatly convex at the periphery and somewhat 

 contracted below ; the fascicle broad, hardly raised, flattish. Suture 

 distinct, but not deep. Aperture high, triangular, narrow above, 

 widened below, with a narrow upper channel, very broadly truncated 

 and rather deeply notched at the base. Outer lip oblique, its upper 

 part nearly straight, the lower moderately curved, much thickened, 

 rounded, smooth, but not reflected, retrocurrent towards the suture. 

 ColumcUa sub vertical, straight, with 5 to 6 somewhat inequidistant 

 subequal strong and flat plaits, sometimes with an additional small 

 plait above ; the columella slightly twisted below and produced into 

 a narrowly rounded beak, extending beyond the inferior end of the 

 outer lip. Inner lip thin, spreading broadly over the body and the 

 lightly convex wall, with a roundly raised outer edge below. 



Diameter, 41 mm. : height. 80 mm. Angle of spire, 50. 



Animal unknown, 



Type in my collection. 



Hab. Spirits Bay, North Island (C. Cooper, Captain Bollons). 



Remarks. Only empty shells have hitherto been available, and 

 the description is therefore somewhat imperfect. The species was 

 discovered near Spirits Bay by Mr. C. Cooper, of Auckland, and later 

 on also collected by Captain Bollons.
