 320. Mangilia Goodingi, Hutton, P.L.S. N.S.W., x, 117; Suter, 

 T.N.Z.I., xxxi, 71. 



Shell acuminately ovate, turriculate, white with series of red dots, 

 axially costate and spirally lirate. Sculpture consisting of 9 to 10 

 prominent plicate axial ribs, continuous up the spire and extending 

 to the base of the last whorl, the interstices somewhat broader than 

 the ribs ; the whole shell is minutely and closely spirally striate. 

 Colour white, ornamented with series of red dots on the ribs, one above 

 the periphery, another near the base of the whorls, and a third towards 

 the base of the body- whorl. Spire acuminate, conic, turriculate, a 

 little higher than the aperture. Protoconch : The nucleus small, 

 globular, the' second whorl broad and low, strongly convex, much 

 contracted toward the suture below. Whorls 7, slightly shouldered, 

 almost flat ; base moderately contracted. Suture distinct. Aperture 

 narrow, angled above, produced below into a narrow and short canal, 

 its base straight. Outer Up thickened by the last rib, lightly convex, 

 with a shallow sinus above. Columella somewhat arcuate. The inner

Hob. New Zealand. 



Remarks. This species and M. Sinclairi are very closely allied, but 

 the protoconchs are quite distinct. In the latter species the brown or 

 reddish spiral bands are continuous, not dissolved into spots, and the 

 ribs do not extend over the beak.

 and persisting faintly down the base ; body-whorl with about 9 ribs. 

 Strong spirals cross the ribs, 2 on the second whorl, 3 above the aper- 

 ture, a fourth and faint fifth further down on the body-whorl, with 

 finer spirals in the interspaces ; base spirally striated. Colour white, 

 chalky (dead shell). Spire conic, turreted, about 1| times the height 

 of the aperture. Protoconch of about 1^ whorls, papillate, smooth.
