DESORIPTIONS. 79 
punctata, A. Ad., but is less acuminated; the colour is 
white, flamed and marbled with orange, transversely lined ; 
there are three or four folds behind the thickened lip, 
sutures finely plicated. This is an interesting shell; it 
shows a passage from such shells as the N. lentiginosa and 
punctata, A, Ad., &c., into N. glans, Linn. 
452 N. lyreformis, Marrat.—Shell ovate, ventricose, longitudinally 
ribbed, ribs curved, transversely grooved, one-third of the 
body-whorl from the base closely granular, pale, with two 
broad olive-green bands, granules white, sutures coronated, 
with a groove-line just below the beads, columella spreading, 
with the ribs protruding through the thin callous, throat 
brown with a white band, closely plicate. China. 
Obs.—While the form of this shell is that of N. gemmulata, 
Lam., the colour and texture resembles that of N. marginulata, 
Lam., and N. nodifera, Powis; the sculpture also shows this inter- 
mediate character. 
389 N. bucculenta, Marrat.—Shell somewhat acuminately-ovate, 
of a pale chocolate brown colour, banded and longitudinally 
striped with darker tints of a similar colour, whorls 
ventricose, smooth, the upper whorls strongly costate, the 
body-whorl deeply grooved at the base, sutures either closed 
or canaliculate, aperture oblong-ovate, columella plicate at the 
base, the callous clearly defined, not spreading ; the outer 
lip is thickened, with two or three folds behind it, thin at the 
edge and slightly coronated, throat closely plicated. 
Philippines. 
Obs.—There appears to be a union of several supposed distinct 
species in this shell. In the first place it resembles the N. elegans, 
Kiener, in its broad form; in the next place it can be associated 
with certain varieties of the N. glans, Linn ; in small specimens 
again, some of the shells are thick and narrow, approaching some of 
the forms of N. compta, A. Ad.; and lastly, the square markings 
closely resemble those on the N. algida, A. Ad. 
47 N. polita, Marrat.—Shell elongately-conical, polished, of a 
brownish-ash colour, with pale bands a little darker than the
