parum productum, ultra labrum haud prominet. Color flavidus; pars 
infima a anfractum a lira secunda, vel tertia (penultimi et ultimi) inde 
caerulescens; lira prima anfractuum superiorum (quae secunda ulti- 
morum) ferruginea. Differt a sequente B. antillarum testa magis elon- 
gata, spira longiore, anfractibus convexis, numero et dispositione lirarum, 
labio minore, lineisque elevatis labrorum.

B. with shell subturreted, longitudinally plicate, transversely lirate, 
noduliferous, yellowish, with convex whorls, ornamented above with a 
transverse brownish line, below with a bluish band; with obtuse trans¬ 
verse lirae on the upper two whorls, on the last about 8; aperture ovate; 
outer lip externally strengthened by a varix; ornamented within with 
four elevated transverse lines; inner lip little dilated, with four elevated 
oblique lines in relief; cheeks yellowish, with three brownish bands. 
Eight whorls rotund, the last one a little shorter in comparison with the 
antecedent ones. Longitudinal plications straight, nine to ten, interstices 
narrower in the middle, vanishing above toward the suture, extended on 
the last whorl to the base. Transverse lirae obtuse where they intersect 
the plications, forming nodules, two on the upper whorls, four on the 
last one, the second more distant from the third, the first and fourth 
small. On the upper angle of the aperture is impressed the usual elevate 
but oblique plication or line on the inner lip, which, little produced, 
scarcely extends beyond the outer lip. Color yellowish; the lower part 
of the whorls, from the second liration on the third (next to the last and 
the last) from thence bluish; the first liration of the upper whorls, (which 
is the second of the last ones). Differs from the following B. antellarum, 
in the more elongate shell, longer spire, convex whorls, in the number 
and disposition of the lirae on the inner lip, and more elevated lines of 
the outer lip. (Translation.)
