(Plate XXXII.) 
Conus suspcARINATUS. Pl. XXXII. f.12,13. Testa turbinata, 
sublevigata, infra rude sulcata, alba, pallidissime purpureo 
tincta, flammulis fuscis irregulariter angulatis longitudina- 
libus, medio interruptis plus minusve in fascias latas duas 
junctis ; lateribus rectis ; angulo subcarinato ; spira prope an- 
gulum convexa, apice acuminato. Variat fasciis duabus latis, 
lineis interruptis cinctis ornata. 
Hab. Nicobar Islands (Mus. Cuming). 
With something of the aspect of C. voluminalis, this shell differs 
from that species in being much more solid and broad. The angle 
is sharpened so as to form almost a keel. The two specimens in 
Mr. Cuming’s cabinet are distinct varieties, one of which has two 
broad chestnut bands, girt by white-spotted brown lines. 
’ Conus straturatus. Pl. XXXII. f. 14. Testa oblonga, sub- 
pyriformis, supra subinflata, infra angustata subtorta, alba, 
pallidissime ceruleo tincta; maculis subquadratis pallide fuscis, 
in fascias duas latas dispositis, et aliis irregularibus ornata ; 
suleis distantibus supra medium subevanidis, infra profundis, 
ad fascias albas apparentibus cincta ; angulo subrotundo ; spira 
via elevata, spiraliter striata, maculis fuscis linearibus radiata; 
apice acuminato ; apertura lata; columella lineari, distincta. 
Hab. Borneo (Mus. Cuming). 
This species belongs to the same group with C. spectrum, but 
most nearly resembles C. collisus. From the latter, however, it is 
distinguished by the thread-like white lines of sulci crossing the 
interrupted bands of colour, giving a paved appearance to the orna- 
mentation. Mr. Cuming possesses several specimens. 
Conus sacitratus. Pl. XXXII. f. 8,9. Testa gracilis, longi- 
tudinaliter minute striata, spiraliter liris leviter elevatis sub- 
distantibus cincta ; alba, fammulis fuscis longitudinalibus seu 
angulatis et super liras maculis sagittatis regulariter picta ; 
lateribus medio paululum coarctatis; spira conica, apice mu- 
cronato; anfractibus minute cancellatis, marginibus internis 
versus apicem elevatis ; sutura lineari. 
Hab. ? (Mus. Denisson) (olim). 
Although this elegantly formed, neatly sculptured, and delicately 
painted shell belongs to the same group with C. marginatus, C. can- 
cellatus, &c., there is no known species with which it comes into 
immediate comparison. It has a cancellated sculpture formed by 
very delicate raised longitudinal lines crossing more raised and distant 
spiral ones ; and besides the longitudinal flames and angular patches 
of light brown-colour, the spiral ridges are ornamented by a series
