Tur Syracuse Fusus. Shell fusiformly turreted, whorls 
transversely ridged and striated, more or less angu- 
lated round the upper part, longitudinally plicately 
ribbed, ribs sometimes rather broad, sometimes 
narrow, nodose at the angle; rusty-red, generally 
zoned with white. 
Lamarck, Anim. sans vert. (Deshayes’ edit.) vol. ix. p. 456. 
Murex Syracusanus, Linnezus. 
Hab. Mediterranean. 
A common inhabitant of the Mediterranean, varying 
considerably in the development of the ribs. 
Species 11. (Mus. Taylor.) 
Fusus conus. Fus. testé elongato-fusiformi, gracillimd, 
spird lanceolato-acuminatd, canali subcontorto, anfrac- 
tibus undique acute et creberrime tenuiliratis, superné 
angulato-declivibus, medio carinatis et compresso-nodo- 
sis; alba, rufo-castaneo ad apicem basinque tinctd, lined

Tue pistarr Fusus. Shell elongately fusiform, very 
slender, spire lanceolately acuminated, canal slightly 
twisted, whorls sharply and very closely finely ridged 
throughout, angularly slanting round the upper part, 
keeled and compressly noduled round the middle; 
white, stained with chesnut-red at the base and apex, 
with an interrupted reddish chesnut line between the 
nodules. 
Lamarck, Anim. sans vert. (Deshayes’ edit.) vol. ix. p. 443. 
Murex colus, Linneeus. | 
Hab. Ceylon. 
Distinguished by its slender elongated growth, whilst 
the periphery of the whorls are characterized by a row of 
nodules with an interrupted brown line between each, after 
the manner of the F. tuberculatus. 
Species 12. (Mus. Cuming.) 
Fusus unpatus. us. testd elongato-fusiformi, crassa, 
solidd, undique superficialiter sulcatis, iris apicem ver- 
sus acutioribus spird acuminata, anfractibus superne 
declivibus, medio fortiter tuberculatis, tuberculis grandi- 
bus, distantibus ; aperture fauce acute liratd; intus 
extusque eburned. 
Tue wavep Fusus. Shell elongately fusiform, thick, 
solid, superficially grooved throughout, ridges sharper 
towards the apex, spire acuminated, whorls slanting 
round the upper part, strongly tubercled in the middle, 
tubercles large, distant; interior of the aperture 
sharply ridged; ivory-white within and without. 
Desuayes, Anim. sans vert. vol. ix. p. 446. noe. 
Murex undatus, Gmelin. 
Fusus incrassatus, Lamarck. 
Hab. Island of Taheite; Cuming. 
This and the F. longissimus are extremely well figured 
by Martini in the same plate (Conch. Cab. vol. iv. pl. 145.) 
and the diagnose of each commences “ Fusus longissimus” 
&e.; they are, however, described as separate species, the 
term “longissimus” not being intended as a specific title 
in the sense adopted by the present form of nomenclature. 
Species 13. (Mus. Cuming.) 
Fusus bonaicaupa. Fus. testd tenuiculd, elongato-fusi- 
formi, gracillimd, canali subcontorto, spird subtiliter 
acuminatd, anfractibus rotundatis, apicem versus longi- 
tudinaliter sulcatis, liris reqularibus acutis, alternatim 
majoribus, undique spiraliter carinatis ; intus extusque 
nived, ad apicem basinque pallidé castaneo tincta. 
Tue LonG-rarL Fusus. Shell rather thin, elongately 
fusiform, very slender, canal somewhat twisted, spire 
finely acuminated, sutures excavated, whorls rounded, 
longitudinally grooved towards the apex, spirally 
keeled throughout with sharp regular ridges which 
are alternately larger ; snowy white within and with- 
out, tinged with chesnut-brown at the base and apex. 
Bory, Encyclopédie Méthodique, pl. 423. f. 2. 
Hab. Ceylon. 
No two individuals exhibiting such a positive distinction 
of growth, as that presented by the F. cols and longicauda 
should be admitted under one specific head. The species 
under consideration may be recognized by the excavated 
character of the sutures, the sharper and less crowded 
development of the ridges, the slightest possible indication 
of nodules round the periphery of the whorls, and by the 
absence of any intermediate colouring. 
November, 1847.
