The specimen o f M . trigonularis, in Lamarck’s cabinet, is only one of this species, with th e varices
filed down to an even edge ; and I may here remark, tha t M . tenuirostris, o f the same cabinet, is M . tenuis-
p in a , with the spines filed off.

A common species. Sometimes the processes o f the varices are short, conical, and n ot branched, wlien
it is M u r e x anguliferuaoULamaxclí, an d Af. Cosíalas of Gmelin, from M a r t in i ,/ . 1029-30, and ilf. Senegalensis
o f the same author, from L e So ra t o f Adanson, t. 8. / . 19. The tubercles beween the varices are rarely
produced into a varix, so tha t the shell has six instead of three varices on each whorl, which proves th a t these
tubercles are what some o f the German naturalists would con sid e ra s abortive varices.
The above four species are distinguished from all the other Múrices, which generally have three varices,
in having a spine like Monoceros on the front o f the outer lip. This character is also found in M u r e x eras-
siapina, and one o r two other long-beaked species.
Mr. T u rn e r informs me, on the authority of the person who collected these shells, tha t the different species
o f rock shell, {Mure x ) of the Pacific ocean have the following geographical distribution :—The M u r e x regius,
and common variety of M u r e x ra d ix , are found a t P a n am a ; further north occurs the wide-variced M u re x
ra d ix ■, and further north still the M u r e x Brassica of L amarck, the Mure.v ducalis of B roderip.

Tentacles separate at the base, on the side o f the base o f the trunk, with the,eyes on short pedicles at
