550 FUNAFUTI ATOLL. 
Caecum vertebrale—off Tutaga in 45-52, 50-60, and 200 
fathoms; off Beacon Islet (Funamanu), at 150; and in 36 fathoms 
north; and 36 fathoms N. 30° W. of Pava. This is evidently from 
its abundance a native of the deeper water. Some of the examples 
from 150 and 200 fathoms have a few brown blotches on the shell. 
Cecum gulosum—dredged at every station with C, vertebrale. 
Columbella varians—36 fathoms N. 30° W. of Pava. 
Marginella iota—36 fathoms N. 30° W. of Pava, off Beacon Islet 
(Funamanu) in 150, and off Tutaga in 45—52 and 200 fathoms. 
Marginella sandwicensis—150 fathoms off Beacon Islet (Funa- 
manu). 
Olivella simplex—36 fathoms N. of Pava. 
Those species which are either new to science or have not been 
yet recorded from Funafuti are as under. 
CEPHALOPODA. 
Octopus tTonGaNnus, Hoyle. 
Hoyle, Chall. Rep., Zool., xvi., 1886, p. 83, pl. viii., figs. 1, 2. 
One male specimen was procured in the lagoon by Mr. A. E. 
Finckh. The species has only been found before at Tonga. 
POLY PLACOPHERA. 
TONICIA sp. 
(Fig. 59.) 
A single mutilated 
median valve of a Chiton 
was obtained at a depth 
of 150 fathoms off Beacon 
Islet (Funamanu). Such 
features as it has, point 
to an affinity with 7’. 
confossa, Gould. The 
rarity of this group in 
the Central Pacific renders the occurrence of this fragment note- 
worthy. Only six species were known to Harper Pease from the 
Central Pacific. In his last paper he stated that,—‘“ The absence 
of Chitonide from Polynesia has been noticed by authors as a 
remarkable fact, abounding as they do* in the surrounding pro- 
vinces, especially on the west coast of America, at Australia and 
New Zealand.”+ 
* The Chitons not the authors.
