CENSUS OF THE OLDER TERTIARY FAUNA OF AUSTRALIA. 385 
Paive (which has been quoted under Urosalpinx, Fusus and 
Peristernia, and lately retransferred to its original generic location 
on anatomical grounds) may make it desirable to view them con- 
generic therewith. 
Subgenus Latirulus. 
M. Cossmann' remarks that my Peristernia actinostephes 
resembles Latirulus subajinis, D’Orb., and consequently, P. 
apicilirata must also be removed thereto. 
Family Buccinip2. . 
Genus Tritonofusus, Beck, 1847, 
This name replaces Sitpho, Mérch, 1852, adopted from Klein, a 
pre-Linnean author. The Australian species, diagnostically known, 
are reduced to 7’. crebrigranosus and 7’. labrosus, by removal of 
Stpho asperulus and S. styliformis to Siphonalia, the former 
under the changed name of S. Jatei, Cossmann. 
Genus Phos. 
Subgenus Lowxotaphrus, Harris, 1897. 
The above name is proposed for anew group with Phos (?) vari- 
cifer, Tate, as its unique type. When describing the species? I 
discussed its affinities with Phos and Nassaria; the differences of 
the aperture and protoconch being dealt upon. In Phos the pro- 
toconch is typically turbinate or even conical, of three or more 
whorls, whilst in Loxotaphrus it consists of one and a half turns, 
the earlier portion being inflated and implanted obliquely. 
Family VoLurTip2. 
In my arrangement of the thirty-two fossil species of Volutes* 
no attempt was made to throw them into groups consonant with 
those employed for the recent and tertiary species, though 
incidental references thereto were made as regards a few species. 
Mr. Harris in his Cat. Brit. Mus. has grouped fifteen of our 
species into the following genera and subgenera :—
