Tornatina.} GASTROPODA. 527 



fleeted over the columella, spreading as a thin callus over the parietal 

 wall. 



Diameter, 2-2 mm. ; height, 4-4 mm. 



Animal unknown. 



Type in the Dominion Museum, Wellington. 



Hob. Off Great Barrier Island, in 110 fathoms. 



Remark. The specific name being preoccupied in Tornatina by 

 A. Adams, 1850, it gives me great pleasure to unite the name of my 

 friend Mr. R. Murdoch with the species.

Tornatina oruaensis, Webster, T.N.Z.I., xl, 1907 (1908), 255, pi. 20, f. 12-15. 



Shell cylindrical, white, of 3J whorls, slightly concave in the crown, 

 above the centre of which projects the smooth protoconch, tilted at 

 an angle of somewhat less than 90. Sculpture : Faint growth-lines, 

 prominent posteriorly, following the curve of the outer lip, the surface 

 scored with fine wavy spiral furrows. Suture deep. Type I : Crown 

 hollow, the tilted apex visible above it ; outer lip longer than the 

 shell, advancing in the centre and rounded anteriorly ; columella 

 arcuate, with a thin but distinct labial pad and a very strong fold, 

 which is thickened anteriorly. Type II : Apex subscalar ; aperture 

 shorter than the shell ; columella with a much slighter fold than the 

 last. (Webster.) 



Diameter, 1-25 mm. ; height, 3 mm. 



Type in Mr. Webster's collection. 



Hob. Orua Bay, Manukau Harbour, in 3 fathoms. 



Remarks. These shells (about fifty), obtained by dredging, show 

 many variations of apex between these types ; the protoconch is never 

 sunk below the crown, as in Cylichna. (Webster.) 



I have not seen this species.

 furrowed, with an impressed top and a papillary apex. Sculpture : 

 Longitudinals the lines of growth are few, sinuous, and very slight. 

 Spirals round the edge of the impressed top is a rounded keel, with 

 an exterior strongish rounded furrow, outside of which is a narrow 

 sharpish keel ; within the apical pore the whorls are sharply keeled 

 above the channelled suture ; the only other trace of spiral striation 

 is behind the outer lip, where the fresh shell shows some trace of a 

 spiral texture. Colour horny yellowish-white. Aperture club-shaped, 

 large, the full length of the shell being a little produced posteriorly,
