Buccinulus gracilis, sp. nov. 
Woorts 8, finely and closely spirally grooved. Body whorl rather con- 
stricted in the middle; the spiral grooves are much finer at the anterior 
end of this whorl, and as they approach the lip, which is very thin and 
sharp. White. 
Length ‘85 inch. Breadth -87 inch. - 
Wellington : collected by Mr. C. Holdsworth. 
This shell is easily distinguished from Buceinulus kirki, Hutton, (the i de 
of which is in the Colonial Museum), by the greater number of whorls, its 
more elongate and less robust appearance, and by the greater number and 
closer proximity of the spiral grooves. 
Buecinulus huttoni, sp. nov. 
Whorls six, with numerous fine spiral grooves. Columella with double 
fold, but more prominent than in the preceding species. Spire very 
short, giving a decidedly robust appearance to the shell. Ground colour, 
white with longitudinal brown wavy lines. 
Waikanae.

concave below, solid, moderately glossy, yellowish or brown, with ote 
brown or white zigzag streaks, spots, or bands, which run lengthwise oF 
& spiral direction, and marked with fine but distinct transverse sme ~ 
plaits, which are more conspicuous towards the suture ; epidermis thin : 
whorls three, rather convex, the last or lowermost exceeding two-thirds ie
