GASTEROPODA. 233 
Fusus incisus, Goutp; Proceed. Boston Soc. Nat. Hist., i. 141. 
May 1849. Expedition Shells, 64. 
SHELL of medinm size and moderate thickness, of an elongated 
ovate form, of a cinereous brown colour, everywhere encircled with 
narrow, deeply impressed strie of a more decided brown colour than 
the interspaces, about ten on the penultimate whorl. The apicial 
whorls have also eight or nine longitudinal undulations. Whorls six 
or seven, convex, the last two-thirds the length of the shell, tapering 
about equally each way ; siphonal beak short, a little recurved. Aper- 
ture one-half the length of the shell, narrow, sub-oval; outer lip regu- 
larly arcuate, crenulated by the impressed lines, and deeply sulcate 
within; pillar lip nearly straight, a little contorted, smooth, purplish- 
brown; whole interior livid brown. 
Length of axis an inch and three-fourths ; breadth seven-eighths of 
an inch. 
Habitat uncertain ; probably New Zealand. 
This buccinoid species should perhaps be grouped with the genus 
Pollia of Gray. It has no remarkable characters except its dingy 
livid brown colour, and the deep cut revolving lines. 
Figures 283, 283 a, two views of the shell.

attenuato: apertura angusta, dimidiam longitudinis teste haud 
@quans, postice angulata ; labro acuto, crenulato ; columella postice 
arcuata, alba, polita.
