placed by Tryon (Man., vol. ITI., p. 60)—he had not seen the 
species—was named by Prof. Tate, loc. cit.. Austrofusus pyru- 
latus. A drawing of its dentition, given on pl. iii., fig. 5, shows 
a three-denticled rachidian and curved, saw-like laterals, and 
definitely withdraws it from Stphonalia, and makes it con- 
generic with /usus australis.

_ This species was also classed by Prof. Tate, loc. cit., as Austro- 
Jusus ; but Tryon regards it as a /usus. Although I have not 
yet been able to determine its dentition, yet from its concho- 
logical characters, there is little doubt it will prove to be a Musus. 
Tate'also makes it a synonym of F. sulcatus, Lam. (An. s, Vert., 
1822, vol. VII., p. 125). Tryon, on the other hand, gives 
Ff, sulcatus of Lam., as a Siphonalia, and I. ustulatus of Reeve 
as a usus. There is little question they are distinct species. 
Although Tryon gives South Australia as the habitat of 7, sul- 
catus, Lam., yet Kiener, in Cog. Viv., when describing and 
figuring the species from the Lamarckian Collection, says the 
locality is unknown. Jam not aware on what authority Tryon 
gives South Australia. ‘The excellent plate in Coq. Viyv., p. 26, 
pl. xiii., fig. 1, is that of quite a different shell from our J. ustu- . 
latus. The former is thin, very ventricose, and has marked, 
slightly wavy, transverse, dark-chocolate-brown spiral lines ; 
whereas the latter is solid, by no means ventricose, much more 
attenuated in the spire, and ornamented only with a little 
scorching on the longitudinal costs. Chenu’s figure of F. sul- 
catus (Manuel de Conchyliologie, p. 140) is evidently not drawn 
from Lamarck’s shell, and is as evidently 7. wstulatus ; here is 
the explanation of Tate’s synonymy. 
Hab.—No locality was known to Reeve, but Angas recorded 
it from St. Vincent Gulf. I have it from three widely separated 
beaches in this Gulf, and dredged in life, but small, at 19-24 
fatho Encounter and Lacepede Bays (D. J. Adcock).

Tryon says (Man. of Conch., vol. ITT., p. 60) ‘this is evidently 
a very much worn specimen, and perhaps not adult; the locality 
also has not been confirmed by subsequent collectors,” i.¢., the 
western coast of New Holland. I have a specimen from Eyre’s 
Sand Patch, which is on the southern coast of Western Australia.

He further remarks, “ Dr. Philippi considered /. Zaylorianus, 
Rve., a synonym, but I do not think the condition of 7”, Dunkeri 
justifies a positive conclusion, If the two species be merged, the
