528 GASTROPODA. [Opisthobranchiu. 



shortly curved across the body, ample in front. Whorls 4, the earlier 

 ones only indistinctly visible in the impressed top ; the nucleus is 

 papillary. Suture deeply channelled, with a sharp keel above it ; 

 this keel runs out not above but on the edge of the funnel-shaped 

 top. Outer Up rises from the inner side of the apical depression and 

 slopes flatly outwards, forming thus the patulous opening of the funnel- 

 shaped depression ; at the apical keel it is angulated ; from this point 

 it makes a convex sweep, with a slight contraction about the middle ; 

 it is patulous and somewhat elliptical in front. Top nearly flat, only 

 the outer lip rises slightly above the level ; the apical depression is 

 funnel-shaped, having a wide converging mouth and a small, not deep 

 hole in the middle, with a papillary apex in the middle. Inner lip : 

 A broadish distinct white glaze extends across the body, on which the 

 curve of the lip is very regularly convex on to the narrow, long, low, 

 and twisted pillar-tooth ; beyond this the columella is slightly con- 

 cave, narrow, a little patulous, and appressed. (Watson.)

8. Tornatina tenuilirata, .Suter, 1909. Plate 23, fig. 1. 



Tornatina tenuilirata, Sut., P. Mai. S., viii, 1909, 257, pi. 11, f. 13. T. pachys, 

 Watson : Murdoch and Suter, T.N.Z.I., xxxviii, 280 ; not of Watson. 



Shell small, cylindrical, mucronate, thin, white, with microscopic 

 spiral strife on the lower half. Sculpture consisting of distinct fine 

 curved growth-lines, and inequidistant microscopic spiral lines on the 

 anterior half of the body-whorl. Colour white. Spire depressed, 

 almost flat, the nucleus only projecting above the last whorl. Proto- 

 conch papillary, smooth and glossy, tilted. Whorls 4, narrowly angled 

 above, the last cylindric, but little narrowed below. Suture chan- 

 nelled. Aperture vertical, nearly as high as the shell, very narrow 

 above, prominently widened below. Outer lip thin, sharp, narrowly 

 rounded above, somewhat advancing at the middle, regularly convex 

 at base. Columella slightly oblique, with a deep-seated fold, forming 

 an inconspicuous angle with the moderately convex parietal wall. 

 Inner lip spreading over the latter as a very thin glaze. 



Diameter, 1-6 mm. ; height, 3-2 mm. 



Animal unknown. 



Type in the Dominion Museum, Wellington. 



Ha}). Off Great Barrier Island, in 110 fathoms. 



Remark. After careful comparison with Watson's description and 

 figure I have come to the conclusion that this species is decidedly 

 distinct. I wish to state that the wrong identification rests with me 

 alone.
