FASCIOLARIA. 
Puate I. 
Genus Fascronarra, Lamarck. 
Testa fusiformis vel pyriformis, interdum magnitudine per- 
ampld, basi plus minusve canaliculati, anfractibus 
sepissimé tuberculatis, nunguam varicosis ; columellé 
plus minusve arcuatd, basi oblique plicaté, plicis inferi- 
oribus majoribus ; aperture fauce striis prominentibus 
elevatis creberrimé radiaté. Operculum corneum. 
Shell fusiform or pear-shaped, sometimes of very large 
size, more or less channelled at the base, whorls most 
frequently tuberculated, never varicose; columella 
more or less arched, obliquely plaited at the base, 
lower plates the larger, interior of the aperture very 
closely rayed with prominent elevated striae. Oper- 
culum horny. 
The Fasciolarie though limited in species, appear to 
constitute a very natural genus, easily distinguished from 
the Fusi by their larger and more solid tubercular growth 
and brilliancy of colour; there are also characters in the 
style of marking, which are not unimportant. In most of 
the species the shell is encircled by fine blackish lines en- 
graved on the surface, arranged two and two throughout, 
and the interior of the aperture is generally radiated with 
strong elevated red lines. Another character by which 
Fasciolaria may be distinguished from Fusws, consists in 
the columella being always distinctly obliquely plaited at 
the base, mostly very strongly so; according to M. Quoy, 
the animals are nearly similar, and it is this affinity which 
has induced that eminent naturalist to connect the two 
genera in one. 
The Fasciolarie ave few in number but pretty generally 
distributed; among the localities noted in the following 
monograph are Ceylon and the Philippine Islands, Australia, 
Western Africa, Panama, Mexico and West Columbia, 
Honduras and the West Indies, Mediterranean and the 
Cape de Verd Islands. 
Species 1. (Mus. Cuming.) 
FASCIOLARIA PAPILLOSA, young. 
For description of this species see Plate VII. 
Species 2. (Mus. Hanley.) 
FAascIOLARIA LUGUBRIS. 
versim irregulariter sulcatd, anfractibus superne angu- 
lato-declivibus, leviter concavis, ad angulum obtuse 
carinatis, apicem versus obsolet2 nodatis; columella 
subexcavatd, lird callosdé superné munitd ; carneo-fus- 
cescente, epidermide olivaceo-fuscd induta. 
THE MOURNFUL Fascrontarta. Shell fusiform, trans- 
versely irregularly grooved, whorls angularly slanting 
and slightly concave round the upper part, keeled at 
the angle, obsoletely noduled towards the apex; 
columella somewhat excavated, furnished at the upper 
part with a strong callous ridge; fleshy-brown, 
covered with a dark olive-brown epidermis. 
Apams, and Renve, Moll. Voy. Samarang. 
Hab. Cape of Good Hope (found at low water among loose 
stones); Adams. 
A well-marked species, quite unlike any of this limited 
genus hitherto described, though of very simple character ; 
in young specimens the interior is of a chesnut-brown 
colour and the upper portion of the whorls less angulated. 
Three specimens were collected during the voyage of the 
‘Samarang’, but the one here figured from Mr. Hanley’s 
collection, formerly in the possession of the Rev. F. J. 
Stainforth, is in finer condition and the only other example 
I have seen. 
Species 3. (Mus. Cuming.) 
Fascronaria princnps. Luasce. testd fusiformi, subampld, 
spiraliter liratd, liris subdistantibus compresso-nodosis, 
interstitiis regulariter concavis ; anfractibus prope su- 
turas concavis, deinde ventricosis, vix angulatis, nodis 
lire mediane prominentibus, apicem versus conspicuis et 
rotundatis ; aurantio-lacted, epidermide rufo-castaned 
crassa indutd, columella vivide aurantio-rufd, apertura 
peculiariter rufo-lineata. 
Tue cuter Fascronarrta. Shell fusiform, rather large, 
spirally ridged, ridges somewhat distant, compressly 
nodose, interstices regularly concave ; whorls concave 
near the sutures, then ventricose, scarcely angulated, 
nodules of the middle ridge more prominent, conspi- 
cuous and rounded towards the apex ; orange cream- 
colour, covered with a thick red-chesnut epidermis, 
columella bright orange-red, aperture peculiarly 
marked with red lines. 
Sowersy, Tankerville Cat. App. p. xvi. 
Fasciolaria aurantiaca, Sowerby (not of Lamarck) by 
mistake in Genera of Shells. 
| Hab. Coast of Peru; Cuming. 
Fase. testé fusiformi, trans- | 
It is scarcely necessary to observe that this magnificent 
species is remarkable for the richness of its colouring, the 
columella a deep orange-red, the epidermis a fine dark 
red-chesnut. 
October, 1847.
