CY C. HEDLEY. 499 



Cardita beddomei, Smith. 

 Smith, Chall. Rep. Zool. xiii. 1885, p. 211, pi. xv., f. 5. 

 A valve of the unusual dimensions of 21 mm. long and 22 mm. 

 high, occurred to me at Twofold Bay. Like the foregoing 

 south, it is an addition to 



Cadulus LuEVis, Brazier. 



Dentalium leave, Brazier, (not D. Iceve, Schlotheim), Proc. Linn. 

 Soc. N.S. Wales, ii. 1877, p. 59; Cadulus Icevis, Pilsbry & Sharp, 

 Man. of Conch, xvii. p. 195.

The author of this species has supplied me with co-types from 

 Darnley I.. Torres Straits. The shell selected for illustration 

 measures directly from end to end, that is along the chord of the 

 arc, 26 mm. It is exceptional in having the small end bitid; 

 most are circular and simple. A submedian consti'iction (mark- 

 ing a rest point in growth 1) noted in the original description is 

 present in but few examples and varies in position. The degree 

 of curvature varies, young shells being more bent. All under 

 the lens are concentrically wrinkled throughout their length. 



Considering the meagre details at their disposal, Messrs. Pilsbry 

 and Sharp estimated with remarkable accuracy the systematic 

 position of the species. 



PUXCTURELLA KESTEVENI, II. sp. 



(Plate xxv., figs. 15, 16, 17.) 



Shell the smallest of the genus known, thin but opaque, 

 elevated, about as high as broad, the summit posterior and 

 excavated by the slit, sides steep, the posterior slope surmounted 

 by a conical projection, being the stump of the apex, which 

 almost overhangs the basal margin. Colour pale brown. 

 Sculpture : uniformly finely shagreened. Aperture oval, broader 

 anteriorly. Slit on the summit, lanceolate, twice as long as
