nambuco. Most of the specimens were of the normal size, but one 
was picked up alive with the very respectable dimensions of 150 mm. 
long and 90 mm. wide. The coloration, etc., agrees closely with 
African specimens. The V. turbinata of Kiener seems to be a 
bleached shell, thin, and without the usual brown tracery on the 
body. It is by most authors referred to ebrea as a variety or sport. 
The references in the literature to V. “ vespertilio” from the West 
Indies are probably based on ill-identified specimens of this species, 
as the V’. vespertilio is not known from America.

The genus, as becomes its age, is widely distributed in tropical 
seas, especially in Australasia, the Indian Ocean and the Antilles. 
The earliest related forms, intermediate between Plejona and Lyra, 
are found in the Upper Cretaceous of India and the earliest Eocene 
of America. The nucleus is shelly and intermediate between 
the minute shelly nucleus of Plejona and the larger and blunter 
nucleus of Voluta. Like Voluta the animal possesses an opercu- 
lum. The verge is curved and provided with a seminal grooye and 
a terminal slender tentacular appendage. The radular teeth have 
few cusps, in marked distinction from those of Voluta. 
The group, from the shell characters, may be divided into two. 
sections, only the first of which is found in American waters.
