126 MR. G. B. SOWERBY ON NEW SPECIES OF SHELLS. [| Mar. 2, 
angled at the upper part; of a darkish brown colour, with an ir- 
regular sprinkling of whitish patches; transversely grooved through- 
out, grooves narrow, rather distant, crenulated; spire elevated, 
rather acute; apex papillary; whorls 9, concave above, with twe 
crenulated grooves ; aperture narrow. 
Specimen unique, in the collection of Dr. Prevost. 
Obs. This very elegant new shell resembles in form CO. aculeifor- 
mis (Reeve), orbignyi (Audouin), &c., but in sculpture and style of 
painting it is quite different from the shells of that group ; its sur- 
face, between the grooves, has a smooth and shining appearance, 
though beneath the lens very fine longitudinal and transverse strize 
may be discerned. As in most Cones, the grooves are much closer, 
deeper, and more strongly crenulated towards the base than at 
the upper part of the body-whorl ; while the two grooves round the 
whorls of the spire are about equal to those of the base. The 
colouring, though simple, is not common in Cones, and quite un- 
known in its congeners in form—the rich brown colouring almost 
covering the shell, relieved by a few irregularly placed whitish 
patches. 
2. Conus MULTILINEATUS. (Plate XXIV. fig. 5.) 
C. testa turbinata, flavescenti-fusca, lineis fuscis punctatis multi- 
cingulata, zona lutescente subcentrali balteata, basin versus 
paulo attenuata, valide costata, superne angulata, levi; spira 
concavo-acuminata, tuberculis parvis coronata, inter tuberculas 
brunneo maculatu ; anfractibus 9, planato-concavis. 
Long. 40, maj. lat. 20, min. 5 mill.; spira alt. 8 mill.; apert. 
long. 32, maj. lat. 42, min. 3 mill. 
A turbinated Cone, of rather solid structure, yellowish brown 
colour, encircled with numerous fine brown dotted lines and a sub- 
central belt of pale yellow, somewhat attenuated towards the base, 
where it is strongly ridged; smooth at the upper part, and angled; 
spire rather concavely acuminated, coronated with small tubercles, 
which are made conspicuous by intermediate brown blotches ; whorls 
9 in number. 
Specimen unique, in the collection of Dr. Prevost. 
Obs. The species most like this in marking is C. lgnarius 
(Reeve), from which, however, it may very readily be distinguished, 
both by its turbinated form and the coronation of the spire. 
Finding this species so like C. lignarius in colour and markings, I have 
been led to examine a large number of specimens of that species ; 
and I find them remarkably uniform, with scarcely any tendency to 
variation, of an oblong, almost cylindrical form, without any sign 
of nodules on the spire. 
3. Trocuus (PoLyoponTA) MIRABILIS. (Plate XXIV. fig. 7.) 
T. testa conica, solidiuscula, corneo-albida rufo-fusco flammulata ; 
anfractibus 10, planato-convewis, ad suturam profunde excavatis, 
spiraliter costis rugoso-grunulatis valide cingulatis, interstitiis 
profundis, plicatis ; spira acuta; basi convexiuscula, granuloso-
