Kanella gaud at a. — Shell pale reddisli-brown^ cancellate, witli 
eleven robust costa to the body whirl^ and several revolving filiform 
lines passing over them, which are more prominent upon the varice 
of the aperture, terminate at its inner edge, and there alternate 
with the raised lines of the fauces ; volutions flattened at their 
summits, abruptly declining to the suture ; canal coarctate, rather 
longer than the spire ; beak rectilinear, reflected at the tip. 
Length one inch. Inhabits the coast of the United States. 
Cabinet of the Academy and Philadelphia Museum. A rather 
common species. 
This generic name I think objectionable, inasmuch as it borders 
too closely upon Renilla, which designates a genus of the class 
Polypi of Lamarck. Montfort’s appellation Buffo is not preferable 
for a similar reason, as it would be liable to be confounded with 
Bvffo, a genus of Reptilia. 
PuLGUR PYRULOIDES. — Shell with spiral striae alternately larger ; 
whirls white, transversely lineated with ferruginous lines, inter- 
rupted or obsolete on the middle ; above flattened, unarmed ; spire 
short ; suture profoundly canaliculate.

Length three inches and four-fifths. Breadth one inch and 
one-tenth. Inhabits the Southern coast. Cabinet of the Academy 
and Philadelphia Museum. 
At first sight this species would be referred to the genus Pyrula, 
but upon inspection it will be observed to have a fold on the colu- 
mella. I formerly mistook the young shells for those of F. canim- 
lata or granum, which they much resemble in form, in the grooved 
sutures, and in the spiral striae j but they dilfer from them in 
having a much less elevated spire, by being entirely destitute of 
armature, either of spines or tubercles, upon the angulated ridge 
of the volutions, and by being marked with colored lines. In this 
last character they approach F. perversus, but they will not be mis- 
taken for that species. 
As the shell advances in growth, the acute edge of the depressed 
top of the whirls becomes obtuse, and in the adult shell it is 
nearly obsolete in which state the almost regular curve of the 
whirl is very like that of Pyrula. 
Seba’s figures above quoted, are probably intended for this
