SHO TION TEL, 
GASTEROPODA OF THE MIOCENE DEPOSITS OF NEW JERSEY. 
Class GASTEROPODA. 
Order PECTINIBRANCHIATA 
Family MURICIDAS. 
Genus MUREX Linneeus. 
MUREX SHILOHENSIS. 
Plate xvu, fig. 1. 
Murex Shilohensis Heilprin: Proc. Acad. Nat. Sei. Phila., 1887, p. 404, 
? Murex sp.? Heilprin: List, Proc. Acad. Nat. Sci., loc. cit. 
“Whorls about seven, angular, flattened on the shoulder, which is crossed 
diagonally by the variceal ridges; varices about eight on the body-whorl, 
subequal, spinosely elevated on the shoulder angulation, and crossed by 
four subequal revolving ridges, which appear double on the crests of the 
varices; only two such ridges on the whorls above the body-whorl. 
“Aperture somewhat more than half the length of the shell, key-hole 
shaped, with the canal broadly reflected. Length nearly .75 inch.” 
The type specimen of this species has the spines on the angle of the 
volution so strongly marked and tube-like as to give the shell very much 
the character of the genus Typhis, still they do not appear to be quite in 
the nature of tubes, but seem to be deflected backwards, and open more 
decidedly on the anterior side than behind; enough so at least to induce 
one to place it rather with Murex than in Typhis. As only a single indi- 
vidual has been observed, it is somewhat difficult to say how far it may have 
varied in this particular. 
Locality: ‘The specimen is from Mr. Ayers’ pits in the Miocene marls, 
near Shiloh, N. J., and belongs to Miss Emma Walter, of Philadelphia, 
from whom it was borrowed through Prof. Heilprin.
