AWATERIA WATSONI Smith. 
Pleurotoma (Drillia) watsoni Smith, Proc. Zool. Soc., 1891, p. 439, pl. xxxiv., 
fig. 10. 
Hab. N.S.Wales:—410 fathoms, off Sydney (type, ‘‘ Challenger”’). 
MirritHaRA gen. nov. 
Shell small, solid, biconical to cylindro-fusiform. Whorls four. 
Protoconch blunt. Colour white or buff, uniform or spotted with brown. 
Seulpture—close revolving cords, sometimes decussated with radial riblets. 
No varix, lip thin, sinus evanescent, columella incrassate, with an in- 
distinct single or double plication. Canal wide and short, throat lyrate 
within. Type, Columbella alba Petterd. 
A characteristic member of this genus is the tertiary fossil Mitra 
daphnelloides Tenison-Woods,”2 from Muddy Creek, Victoria. This was 
afterwards transferred by Tate and Cossmann to Mitromorpha.?? The 
ficure of the tertiary fossil Cordieria conospira Tate,** suggests that 1t may 
belong here also. The recent African species Witromorpha volua Sowerby,”° 
is probably co-generic. 
Probably Mitrithara is related to Antimitra.26 I hayve-not the means 
to institute a comparison, but understand from Mr. Iredale that he 
considers them distinct.
