placed by Tryon (Man., vol. III., 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. ili., fig. 5, shows 
a three denticled, rachidian and curved, saw-like laterals and 
definitely withdraws it from Siphonalia, and makes it con- 
generic with Fusus australis. 
3. F. ustulatus, Reeve. 
Ref.—Conch. Icon., 1848, fig. 66. 
This species was also classed by Prof. Tate, loc. cit., as Austro- 
Jusus ; but Tryon regards it as a Pusus. 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 Musas. 
Tate also makes it a synonym of & sulcatus, Lam. (An. s, Vert., 
1822, vol. VII., p. 125). Tryon, on the other hand, gives 
F. sulcatus of Lam., as a Siphonalia, and F. ustulatus of Reeve 
as a Fusus. There is little question they are distinct species. 
Although Tryon gives South Australia as the habitat of /’, sa/- 
catus, Lam., yet Kiener, in Cog. Viv., when describing and 
figuring the species from the Lamarckian Collection, says the 
locality is unknown. J am not aware on what authority Tryon 
gives South Australia. The excellent plate in Coq. Viv., p. 26, 
pl. xiii., fig. 1, is that of quite a different shell from our /’, wstu- 
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 coste. Chenu’s figure of 7. sul- 
catus (Manuel de Conchyliologie, p. 140) is evidently not drawn 
from Lamarck’s shell, and is as evidently /. ustulatus ; 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 
fathoms. Encounter and Lacepede Bays (D. J. Adcock).

Tryon says (Man. of Conch., vol. III., p. 60) ‘this is evidently 
a very much worn specimen, and perhaps not adult ; the locality 
also has not been confirmed by subsequent collectors,” z.¢., 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 /. Z'aylorianus, 
Rve., a synonym, but I do not think the condition of /. Dunkeri 
justifies a positive conclusion. If the two species be merged, the
