ON THE IDENTITY AND RELATIONSHIPS OF BUCCINUM 
DERMESTOIDEUM, Lam.: PSEUDAMYCLA, Nov. GEN.

Tne object of the present note is to dispel the existing confusion 
regarding the designation of the common Australian Molluse which 
is perhaps best known to collectors as Colwmbella lineolata, Pse. 
Lamarck appears to have been the first to meet with the species, 
and his description’ of Buccinum dermestoideum, although not a very 
full one, would apply perfectly well to the shell subsequently figured * 
under this name by Kiener from the Lamarckian collection. Kiener’s 
figure is unmistakably intended to represent the Australian species, 
and not Nassa cornicula (Olivi) as has generally been assumed by 
later authors in consequence of both Lamarck and Kiener having 
given the Mediterranean as the habitat of B. dermestovdewm (as also 
of so many other forms known not to occur in that sea). The equally 
erroneous locality ‘ West Indies’ came next to be associated with this 
species: the specimens from the Cumingian collection, now in the 
British Museum, that were figured by both Sowerby* and Reeve * 
as Columbella dermestoides, being stated to come from that region. 
Angas® was the first to record the true habitat of this Mollusc, and 
he correctly identified specimens from South Australia and from Port 
Jackson as belonging to the species figured by Kiener ; but, at a later 
date, imagining that his determination must have been erroneous in 
view of the discrepancy in the recorded distribution, he adopted 
Pease’s manuscript name of Columbella lineolata. Meanwhile Pease, 
considering Lamarck’s species to be identical with Olivi’s buceinum 
corniculum,® had renamed’ the Australian shell Colwmbella maculosa, 
a name which he and others have frequently misquoted as maculata. 
To make matters worse, specimens in the British Museum have for
