Bulimus (Liparus) gratwicki Cox, 1899 Fig. 8D

Bulimus (Liparus) gratwicki Cox 1899: 435, figs 1-3; Smith 1992: 103.

Type locality.

"About 50 miles east of Israelite Bay, Western Australia, two miles from the edge of the cliffs".

Label.

"50 miles E of / Israelite Bay / WA", taxon label in Cox’ handwriting. See Remarks.

Dimensions.

"Length 30 mm. Width about the middle of the body whorl 10 mm"; holotype H 29.5, D 10.3, W 7.4.

Type material.

AM C6376, two syntypes; AM C127559, eight syntypes (ex Cox coll.).

Remarks.

According to B.J. Smith (1992) the two specimens in lot C6376 are syntypes; they are accompanied by a type written label stating "Type figd P.L.S.N.S.W. XXIV, p. 435 / Isrealite [sic] Bay, W.A. / Pres. Dr. J. C. Cox". These specimens are, however, smaller than Cox stated and both are unlikely to have been figured. The largest specimen of lot C127599 fits the dimensions given by Cox better and matches the figure. These specimens are accompanied by the label mentioned above with Cox’ handwriting; a second label read reads "fr: near Israelite Bay / W.A." and also bears the taxon name in the handwriting of Cox. The status of this taxon needs further clarification. The type locality is well known for fossil marine deposits; all museum material was collected as shells only, and the shape of this taxon is aberrant within the genus Bothriembryon , leaving doubt about its systematic classification.

Current systematic position.

Status to be determined.
