438 FUNAFUTI ATOLL. 
lip simple, sharp, columella arched, canal produced and recurved. 
Length 18, breadth 8 mm. 
Several dead specimens collected on the lagoon beach of Funa- 
futi. 
CERITHOPSIS EUTRAPELA, MJelvill & Standen. 
Melvill & Standen, Journ. Conch., vii., 1896, p. 301, pl. x, 
fig. 52. 
Three specimens, one mauve, the others white, from the lagoon 
beach of Funafuti. 
CERITHOPSIS ELECTRINA, Sp. nov. 
(Fig. 26). 
\ Shell tall, slender, 
; thin and translucent. 
Colour uniform pale 
amber, except a glassy 
white topmost whorl. 
Whorls nine in my 
example, whose tip is 
broken. Sculpture— 
on the earlier whorls 
proportionately fewer, 
on the last, six spiral 
alternately larger and 
smaller rows of crowd- 
ed gemmules, which 
also regularly succeed ~ 
Fig. 26. one another in longi- 
tudinal order, being 
continued across the suture from whorl to whorl and” ascending 
the spire obliquely. The individual gemmules, as seen in profile 
are much elevated, seen in full face are oval; those of the upper 
four rows of the last whorl are impressed and bisected by a shallow 
transverse groove, invisible in profile, but apparently doubling 
the transverse rows of gemmules when seen in full face. Above 
the first and below the fifth row, the longitudinal axis of each 
continues as a pillar, giving a fluted aspect to the broad and 
deep sutural excavation. The lowest row is swallowed by the 
suture of the subsequent whorl. Beneath the sixth row the shell 
is much undercut and then tapers to the columella, The aperture 
is nearly square with sharp outer lip, arched columella, and very 
short perpendicular canal. Length 44, breadth 14 mm. 
One specimen from the lagoon beach of Funafuti. 
This appears to be distinguished from other Pacific Cerithiopsis 
by the more numerous rows of closely packed granules.
