FROM THE LAGOON AT FUNAFUTI. 199 
Gypsina vesicularis (P. & J.), Carter, 1877, Ann, Mae. Nat. Hist. ser. 4, 
vol. xx. p. 173. 
G. vesicularis (P. & J.), Egger, 1893, Abhandl. bayer. Ak, Wiss., math.- 
phys. Cl. ii. vol. xviii. p. 382, pl. xiv. figs. 20-25. 
This species is usually found accompanying the spherical form 
G. globulus, into which it appears to graduate, but very rarely. 
On the other hand, it frequently shows affinities with the thinner 
varieties, by having a peripheral flange around the mound-like 
test. 
Lagoon, Funafuti. Sample 1 (10 fathoms); sample 2 (153 
fathoms); sample 4 (23 fathoms): sample 5 (24 fathoms) ; 
sample 6 (21 fathoms); sample 8 (26 fathoms); sample 11 
(25 fathoms); sample 13 (26 fathoms); sample 15 (19 fathoms) ; 
sample 16 (20 fathoms) ; sample 17 (12 fathoms); sample 18 
(73 fathoms). 
GYPSINA VESICULARIS (P. g& J.), var. Discus, Goés. (Pl. 19. 
fig. 13.) 
Tinoporus vesicularis (P. & J.), Goés, 1882, Sv. Vet.-Akad. Handl. 
vol. xix. No. 4, p. 104, pl. vii. figs. 245-247. 
Gypsina vesicularis (P. & J.), var. discus, Goés, 1896, Bull. Mus. Comp. 
Zool. Harvard, vol. xxix. No. 1, p. 74, pl. vil. figs. 4-6. 
Upon this remarkable little variety Dr. Goés wrote as 
follows * :— 
“A variety closely allied to the type, from which it differs 
only in its lenticular shape and its more plainly differentiated 
set of the central cycle of chambers. It is not found affixed. 
Caribbean Sea, 400 fathoms ; scarce.” 
This is one of the most distinct varieties of the G. vesicularis 
type. The little button-shaped tests are usually depressed in 
the central region on both sides. It is noteworthy that this 
form was absent from the samples near the margin of the 
lagoon, appearing to prefer the quieter waters and at greater 
depths. This fact is further corroborated by Goés’ record of its 
occurrence at 4.00 fathoms. 
Lagoon, Funafuti. Sample 4 (23 fathoms); sample 5 (24 
fathoms); sample 6 (21 fathoms); sample 7 (24 fathoms) ; 
sample 8 (26 fathoms); sample 10 (26 fathoms); sample 14 
(16 fathoms); sample 15 (19 fathoms).
