T. MAUGERI Wood. PL 10, figs. 25-27. 



Shell conical, with nearly straight sides carinated, solid, thick, 

 false-umbilicate, reddish or yellowish brown, more or less dotted 

 minutely with a slightly darker shade; whorls about 8, flat above, 

 the sutures scarcely marked ; the first whorls of the apex when not 

 smooth by erosion are spirally 1 irate, the lira; dotted with red; 

 succeeding whorls very closely, finely granulate in spiral series, the 

 last whorl with about 7 rows of granules above, carinate at the 

 periphery, slightly deflected anteriorly; base nearly flat with nu- 

 merous (15 to 20) close finely beaded concentric lirula?; aperture 

 very oblique, tetragonal; upper lip straightened, wrinkled within; 

 outer and basal lips thick, curved, crenulate within ; columella very 

 oblique, its edge denticulate, slightly tortuous above, and inserted in 

 the center of the axis, below terminating in an acute or squarish 

 narrow tooth ; parietal wall and umbilicus rugose, the latter bound- 

 ed by a plicate-denticulate rib. Alt. 20-25, diam 25 mill.

A handsome species, formerly very rare. The form is more strict- 

 ly conical than usual in Ounculus. The fine granulation nearly 

 uniform, color, minutely dotted with darker and beneath usually 

 with white, are characters separating maugeri from other species. 

 The specimens before me are from Port Jackson, collected by 

 Brazier. 



T. NODULOSUS A. Adams PL 13, fig. 3. 



Shell turbinate-conoid, imperforate, whitish, variegated with red; 

 whorls transversely silicate, ornamented with grnnose cinguli, above 

 with a coronal series of tubercles ; suture canaliculate; last whorl 

 spirally sulcate, at the periphery tuberculate, the base rather flat- 

 tend, concentrically gran ose-1 irate ; columella solute above, tortuous, 

 anteriorly tuberculate; margin of the umbilicus crenulated; lip 

 transversely sulcate within, margin dentate-lirate. (A. Ad.)

Clancu1u* noditlosus A. AD. P. Z. S. 1854, p. 39, t. 27, f. 2. 



This species has most of the characters of a Clanculus, but the 

 whorls are nodulous and not granular. (Adams.) 



The pecies has not been been noticed by Tasmanian nor Aus- 

 tralian conchologists,
