F. canaliculata, both of which are 
exceedingly common in sandy 
shore stations from Cape Cod 
southward. 
F. carica. The largest univalve 
north of Hatteras, most easily rec- 
ognized by its pear-shaped shell, with 
simple suture and brilliant vermilion 
aperture. The anterior canal islong

Fulgur canaticulata. F. carica frequents almost any sort of bottom. 
In Long Island Sound they are common on stony 
ground, but they do not attain the maximum size and the high degree of 
aperture-coloration characteristic of those taken along the New Jersey 
shore, on sandy stations exposed to the surf. The string of curiously 
shaped capsules containing the eggs of Fulgur is shown in Plate I. 
F. canaliculata often occurs associated with the last. It does not 
attain quite the same size, but specimens of both species are, on the
