The specimen of M. trigonularis, in Lamarck’s cabinet, is only one of this species, with the varices 
filed down to an even edge ; and I may here remark, that M. tenuirostris, of the same cabinet, is M. tenuis- 
pina, with the spines filed off. 
Murex monodon. Soiv. Tank. Cat. n. 1703. 
Murex inflatus. Lam. 
Murex ramosus. Lam. — Martini, f. 980-81. 
A common species. Sometimes the processes of the varices are short, conical, and not branched, when 
it is Murex anguliferus of Lamarck, and M. Costatus of Gmelin, from Martini, f. 1 029-30, and M. Senegalensis 
of the same author, from Le Sorat of Adanson, t. 8 ./. 19. The tubercles beween the varices are rarely 
produced into a varix, so that the shell has six instead of three varices on each whorl, which proves that these 
tubercles are what some of the German naturalists would consider as abortive varices. 
The above four species are distinguished from all the other Murices, which generally have three varices, 
in having a spine like Monoceros on the front of the outer lip. This character is also found in Murex cras- 
sispina, and one or two other long-beaked species. 
Mr. Turner informs me, on the authority of the person who collected these shells, that the different species 
of rock shell, {Murex') of the Pacific ocean have the following geographical distribution : — The Murex regius, 
and common variety of Murex radix, are found at Panama ; further north occurs the wide-variced Murex 
radix ; and further north still the Murex Brassica of Lamarck, the Murex ducalis of Broderip. 
RANELLA. 
Tentacles separate at the base, on the side of the base of the trunk, with the eyes on short pedicles at 
their base, trunk very large and very long. {Ran. tenuis). 
Ranella clathrata. 
Shell ovate, lanceolate, solid, white, closely cancellated, with equal fine longitudinal and spiral ridges, 
sub-tubercular at the crossing; spire conical, rather longer than the mouth ; whorls convex; varices riblike, 
compressed, cancellated. Mouth ovate, outer lip crenulated, inner lip and throat smooth, canal short, open 
Axis i inch. 
Inhab. Atlantic Ocean.
