GENUS BUCCINUM. 3

Buccinum Tranquebaricum, and has called the second, Pur- 
PuRA melanostoma ; he has given a figure of these two species in 
his Genera, No. 25, pl. 5, fig. 5 et 6. 
The difference between young specimens and adults, has led 
into this error: the latter, much larger, have their transverse 
striz more prominent; and the longitudinal folds of the lowest 
whirl, which are distinguished in a very striking manner upon 
the young specimens, disappear insensibly with age. 
38. BUCCINUM COROMANDELIANUM, Lam. The Coro- 
mandel Buccinum. 
(Collect. Mass. Lam.) Last. pl. 939, fig. 34, a. 
Pl. XXII, fig. 85. 
B. testa ovata, longitudinaliter plicata, tranverse sulcata et striata, rufes- 
cente ; plicis nodiferis; ultimo anfractu superne angulato ; spira exsertius- 
cula ; apertura alba ; labro crassiusculo, intts striato. 
Shell ovate, thick, solid, bi-conical, whitish, covered with a 
reddish epidermis, having nine or ten longitudinal folds, more 
strongly marked upon the last whirl, rarely prolonged as far as 
the base, and regularly divided into tubercles by more promi- 
nent transverse striz, the interstices of which are furnished 
with other much finer and very approximate striz ; spire ob- 
tuse at its summit, composed of five or six slightly distinct 
whirls ; the lowest very broad, flattened at its upper part, and 
sub-angular; aperture white, ovate, narrowed at its base, 
canaliculated at its upper part, at its union with the lip which 
is thin and denticulated at the edge, striated within. Exter- 
nally, in adult shells, a pretty prominent varix is observed. 
Columella slightly bent, furnished throughout its whole length 
with small nodules. 
Length 1 inch. Width 6 lines. 
Inhabits the Indian Ocean, the coasts of Coromandel, near 
Tranquebar, the Atlantic Ocean, the coasis of the Island of 
Cuba.
