 Parkinsonianum, Perry : Kesteven, I.e., 464 (description of protoconch). 



Shell small, solid, shouldered, nodulosely costate and spirally 

 lirate. Sculpture : The whole shell, except the protoconch, finely 

 spirally striate ; on the last whorl there are 2 distant and more pro- 

 minent stride crossing the nodules upon the angle, and 2 upon the 

 base, all being minutely granulose ; the lirse on the neck of the canal 

 are alternately finer and stouter ; axial sculpture consisting of strong, 

 rounded varices, almost in the same direction on alternate whorls ; 

 between the varices are 4 to 6 large, elongate, rounded knobs. Colour 

 yellowish-brown, the spiral strise articulated with brown and white, 

 protoconch with brown radiate lines ; aperture white within. Epi- 

 dermis thin, horny, yellowish-green, with short bristles upon the 

 granules. Spire elevated conic, a little higher than the aperture 

 (canal excluded) ; outlines straight. Protoconch of 3J whorls, smooth, 

 convex, the nucleus very minute. Whorls 8 to 9, first rather slowly 

 increasing, with a high shoulder ; base moderately concave. Suture 

 impressed, undulating. Aperture a little oblique, ovate, angled above, 

 produced below into a moderately long and narrowly open canal, 

 which is turned a little to the left and curved backward. Outer lip 

 strongly varicose, with a groove inside under the varix, margin sharp. 

 Columella vertical, arcuate, narrowed to a point below. Inner Up 

 thin, rather broadly expanded, and extending over the parietal wall, 

 which has a minute plait below the angle of the aperture. 



Diameter, 12-5 mm. ; height, 22 mm. (specimen from the Bay 

 of Islands). Specimens from Port Jackson, Australia, measure 

 21-5 mm. by 36 mm.
