436 FUNAFUTI ATOLL. 
by the “Challenger” at Fijiand Tonga, and under the synonym of 
C. lineatum, Lk., is reported by Melvill and Standen from the 
Loyalties ; and by Schmeltz from Cook’s Islands. 
CrERITHIUM PHAROS, Hinds. 
Tryon, Joc. cit., p. 149, pl. xxix., fig. 68. 
Mr. G. Sweet brought one specimen from Funafuti. Tryon re- 
ports this from Fiji and the Paumotus. In this Museum it is 
represented from New Caledonia, New Hebrides, and Hawaii. 
CERITHIUM ELEGANTISSIMUM, Sp. nov. 
(Fig. 24). 
Shell tall, narrow, ovate fusiform, with a prominent 
varix behind the last whorl, flattish beaded whorls 
and a deeply excavated suture. Colour, russet 
brown, shading on the base into burnt umber, 
irregularly picked out on longitudinal ribs with 
white. Whorls eleven, rather flattened, separated 
by deep and sharply incised sutures, last whorl 
almost equalling in length the remainder, and no 
broader than the penultimate. Sculpture—weak 
longitudinal ribs continuously and perpendicularly 
) cross the lower three whorls, fading away on the 
/ periphery of the last. These form gemmules on 
the spiral cords; on the earlier whorls these can 
be also traced. A particularly stout varix occurs 
Fig. 24. lon the last whorl opposite the aperture, a corner 
of which is shown in the illustration. Immediately 
beneath the suture winds a slender cord; four spiral rows of 
gemmules encircle the space between it and the periphery, the 
uppermost of which tends to split into two; the remaining space 
between the periphery and the anterior extremity is occupied by 
seven simple cords which become more slender and close anteriorly ; 
the upper whorls have but two beaded cords. ‘The aperture is 
perpendicular and oval, strongly variced without and consequently 
shelved within; columella arched, with a thick brown callus ; 
canal very short and wide, slightly recurved. Length 5, breadth 
2 mm. 
Abundant on stones in shallow water in the lagoon at Funafuti. 
A specimen before me from Thursday Island, Queensland, 
differs slightly from the above in the greater prominence of the 
longitudinal ribbing. 
CONTU MAX, gen. nov. 
A genus of the Cerithiide, nearest allied to Cerithiopsis. It 
shares with that the excavated base, the produced canal, and the 
unfinished aperture ; but differs by greater size, broader shell,
