Guvers’ Fusus. Shell somewhat pyriformly ovate, spire 
rather short, whorls depressly flattened round the 
upper part, concentrically fimbriated with conspicuous 
erect close-set lamellae, the interstices between which 
are neatly latticed ; blueish-white, interior of the aper- 
ture deep reddish-chesnut.

Hab. Strait of Magalhaens. 
Chiefly distinguished from the following species by 
having the interstices between the lamin more or less 
distinctly latticed. 
Species 14. (Fig. a, 6, and c, Mus. Cuming.)

Tue LacintatTeD Fusus. Shell ovate or fusiformly ovate, 
whorls depressly flattened round the upper part, con- 
centrically fimbriated with large rather distant 
lamellz, the interstices between which are smooth; 
blueish-white, interior of the aperture deep reddish 
chesnut.

Buccinum laciniatum, Martyn. 
Murex lamellosus, Gmelin. 
Murex foliaceus minor, Chemnitz. 
Hab. Chonos Archipelago ; Capt. Graves, R.N. 
Easily distinguished from the preceding species by the 
more distant and stronger development of the lamine, and 
by the absence of any latticed sculpture in the interstices. 
Both are characterized by a rich reddish-chesnut deposite 
of colouring in the interior. 
Species 15. (Mus. Brit.)

Fusus proposcrpirervs. Ls. testd perampld, fusiformi, 
anfractibus spiraliter sulcatis, superné concavo-decli- 
vibus, medio ventricosis, angulatis, conspicue carinatis,

mide sericed induta. 
THE PROBoscIDIFEROUS Fusus. Shell very large, fusi- 
form, whorls spirally grooved, concavely slanting 
round the upper part, ventricose in the middle, angu- 
lated, conspicuously keeled, keel nodose towards the 
apex; fawn-yellow, covered with a beautiful silky 
epidermis. 
Lamarck, Anim. sans vert. (Deshayes’ edit.) v. ix. p. 449. 
Hab. Port Essington, New Holland. 
This gigantic species presents two very distinct varieties, 
one in which the whorls are rounded, the central keel 
scarcely nodulous, and the general growth more contracted ; 
another in which the whorls become more sharply angled 
and concave round the upper part, the keel being rather 
prominent, and the shell altogether more elongated. 
November, 1847.
