GENUS BUCCINUM. O7 
longitudinal folds and very approximate transverse striz, which 
form flattened granulations ; the lowest of these whirls is very 
large. Aperture ovate, emarginated at the upper part, at its 
union with the right lip, which is rather thin, and striated 
internally ; columella arcuated, covered by the left lip; which 
is enlarged into a whitish, wide, and thick callosity, upon the 
body of the lowest whirl. The color of this shell is of a 
reddish brown, with one or two transverse bands upon the 
middle of the lowest whirl. 
Length 7 lines: Width 5 lines. 
Inhabits the China Seas, the coasts of New Ireland, and of 
Vanikoro. 
This little shell has been described by Quoy and Gaimard, 
and figured in their Voyage de l’ Astrolabe, pl. 32, fig. 25 and 
26, under the name of Buccinum globulosum. Waving already 
a Buccinum thus named, we have given to this the name of 
clathratum. Some specimens of this little shell are larger and 
more elongated; the gibbosity, nevertheless, exists, and the 
callosity is reddish, edged with a chestnut-colored band.

Shell thick, smooth, ovate, somewhat gibbous upon the 
back of the lowest whirl, flattened and widened upon the 
sides; spire short, acute, formed of five or six whirls ; 
aperture ovate, smooth and white; the interior of the cavity 
brown ; right lip margined without, smooth within, joining 
towards the top a large polished callosity, by which the colu- 
mella and inferior surface of the whirls are entirely covered.
