Awateria Snter. 



Awateria Suter, N.Z. Geol. Surv., Pal. Bull. No. 5, Pt. I., 1917, p. 57, type 



Aivateria streptophora Suter. 



In general shape and sculpture the type of this genus is reminiscent 

 of Arcularia, the protoconch is comparatively large; the fasciole runs 

 between the wreath of subsutural nodules and the upright ribs ; the canal 

 is shoi't, wide, and effuse. From Epideira, to which, it seems to be related, 

 the larger protoconch, few and rapidly increasing whorls, subcylindrical 

 form and shallow sinus of Awateria readily distinguish it. Hitherto the 

 genus has only been known from the Pliocene of New Zealand. Now it 

 is proposed to utilise Awateria for the reception of Pleiirotoma challeugeri 

 Smith, a recent deep water species from off Sydney. 



Awateria challengeri Smith. 



Plearotoma (Drillia) challengeri Smith, Proc. Zool. Soc, 1891, p. 438, 

 pi. xxxiv., fig. 7. Id. Hedley, Proc. Linn. Soc. N.S.W., xxvi., 1903, 

 p. 22. 



Hab. N.S.Wales:— 410 fathoms, off Sydney (type, "Challenger"); 

 300 fathoms, off Sydney (self). 



Awateria crossei Smith. 



Pleurotoma (Drillia) crofsei Smith, Proc. Zool. Soc, 1891, p. 439, pi. xxxiv., 

 fig. 8. 



Hah. N.S.Wales:— 410 fathoms, off Sydney (type, " Challenger "). 



This classification of crossei, hoylei, and watsoni is merely tentative. 

 Specimens of these species are not available for study, and their illustra- 

 tions are not satisfactory.
