MUREX. ~ 305 
the delineations in the older iconographies are not readily to 
be distinguished from certain varieties of a species so variable ~ 
in the disposition of its colouring as the present one. The 
“sutura geminata,” and the preference of Lister 711 to 710 
(a characteristic representation of distans) are strong arguments 
in favour of the received identification. The species is a native 
of the West Indies. 
MUurvex clathratus. 
The Fusus Bamfius (Donov. Brit. Shells, pl. 169, f. 1) of 
authors still reposes in the box marked for this species in the 
Linnean collection, and exactly answers to the description and 
recorded locality in the ‘Systema.’ Although the cited figure 
of Klein is not so unlike it, and looks plicated, it was only a 
distorted copy of Lister, pl. 926, f. 19, which 1s wholly destitute 
of folds. 
MUurex Dolavitane, 
The Triton dolarium of authors (Knorr, Délices Yeux, pt. 2, 
pl. 24, f. 5) is marked for this species in the Linnean collection, 
and agrees with its description. The cited figure of Bonanni, 
which represents a white Portuguese shell, has also been 
referred to it, though with doubt, by Lamarck and others; it 
was probably intended for it, yet the tail is delineated as too 
produced for an adult example, and the magnitude as too great 
for an immature one. It is strange that plate 52, f. 20, 21, of 
Seba’s third volume, where the species was characteristically 
enough portrayed, has not been quoted by Linneus: he did 
not, however, possess that costly publication. 
Uvex corneus. 
The Fusus lignarius of authors (Kiener, Coq. Viv. Fus. pl. 22, 
f. 1) is marked for this shell in the Linnean collection, and
