A REVISION OF THE AUSTRALIAN TURRIDH—HEDLEY. 255 
The shell of Cluvus is characterised by the following features :—Flat 
indefinite fasciole, indicated only by the curve of growth lines; a smooth 
subulate protoconch. An insinuation of the outer lip, near the base, like 
that of Strombus; a major sculpture of prominent arched scales on the 
shoulder, and a minor seulpture of dense, microscopic, waved, spiral striz. 
The animal was figured by Quoy and Gaimard in the atlas of the zoology 
of the Astrolabe4® An operculum of C. vidualoides Garrett from Cebu, 
Phillipines, is here shown (PI. xlv., fig. 51) to have a medio-lateral nucleus. 
The specific identity of the genotype Strombus lividus was left mm 
doubt by Hanley *® when he studied the Linnean collection, and it has not 
been decided since. I therefore wrote to Dr. Nils H. Odhner, of the 
National Museum of Sweden, inquiring if he could obtain any information 
on the subject. He kindly replied (21st February, 1918) that he had in 
turn yeferred to Professor Wiren, in charge of the museum at Uppsala, 
where the Linnean types are, who answered: “A specimen labelled by 
Thunberg as Strombus lividus, Mus. Gust. Ad., is present here, and it may 
be considered with great probability to be the same as Linne described in 
the Mus. Ludovice Ulrice, 1764.” This type specimen was submitted to 
Dr. Odhner, who described it as corresponding in shape, size, and colour 
to Pleurotoma echinuta, as figured by Reeve.” The identifications of 
Strombus by Chemnitz and Solander‘s are thus shown to be erroneous. 
CLAVUS ZNEUS sp. 10v. 
(Plate xlv., fig. 46.) 
Shell small, solid, cylindro-fusiform, polished, constricted at the 
sutures. On decollate specimens six whorls remain, divided by linear 
sutures. Colour amber-brown, with ochraceous reflections. Sculpture :— 
Ribs prominent, arcuate, each slightly overhanging the one below, seven 
to a whorl, consecutive on the spire, smaller on the last whorl where they 
do not reach the base; on the base and snout are six revolving threads. 
Aperture rather wide, flanked by a tall and thick varix; edge of lip thin, 
insinuate at the base; columella perpendicular and concave; canal short 
and wide; sinus wide and shallow; a prominent callus knob at the lip 
insertion. Length 11 mm., breadth 4 mm. 
This resembles Clavus fusconitens Sowerby, but is much smaller, 
proportionately narrower, with fewer and more prominent ribs. 
Hab. Queensland :—5 to 8 fathoms, Murray Island (self).
