S trombus pugiloides n. .sp. 
The shell for which I propose the above appellation was 
considered to be Strombus pugilis b}^ Mr. Carrick Moore. 
The name was printed fragilis in his paper in the 
Journal of the Geological Societ\’, vol. xix, p. 51 1. In my 
papers on the tertiar\’ fos.sils of Jamaica and the Westindies 
the species was recorded under the name Str. pugilis. In 
ordinary specimens like tho.se u.sually found in Jamaica, 
Haiti, and elsewhere, the only well-marked differences that 
can be noticed between the fossil shell and the recent 
Strombus pugilis are that in the former the last whorl is 
usuall}’ devoid of the spiniform tubercles and that the shell 
is of shorter and broader figure. But some examples 
supplied me by my friend Mr. Vendrj'es exhibit an unex- 
pected character. They show chevron-shaped bands of 
color, about 12 — 15 on the last whorl. Each band takes 
the .shape of a V, the apex of which occurs near the middle 
of the whorl and forms an angle of about 30° pointing 
backwards or awa}- from the aperture. These bands of 
color are about 2 mm. wide and the spaces between them 
are about 3 mm. Numerous specimens of the recent Str. 
pugilis have pas.sed through m3’ hands, but I have never 
noticed the .slighte.st approach to such a character. The 
recent shell is pale red or pink only relieved by an indis- 
tinct band of paler tint following the middle of the whorl. 
A less constant difference ma}' be found in the low rounded 
lamellar dentition inside the outer lip which is ver}’ faint 
or altogether wanting in Strombus pugilis, but more marked 
in the fossil.
