FORAMINIFERA OF.THE FUNAFUTLI ATOLL. 383 
Of the foregomg samples of foraminiferal sands from the 
seaward beaches of Funafuti, that from Avalau Islet is by far 
the richest in organisms. The Foraminifera are there in great 
profusion, and the species very numerous for a coral area; the 
specimens themselves are beautifully preserved, even down to 
the most delicate ornamentation of spines and the perfect 
contour of the shell in many of the fragile forms. 
Besides the Foraminifera we find in the sand of Avalau Islet 
fragments of calcareous Alge, spicules of a Calcisponge, Aleyo- 
narian spicules, a few Heteropods and numerous Ostracoda ; 
the valves of the last-named organisms are more than usually 
abundant and varied, and these, together with other Ostracoda 
from Funafuti, will be enumerated and described in a separate 
paper. 
‘fhe sand here examined from Fongafale Islet is water-worn 
and perhaps wind-polished, so that the result—the occurrence of 
five species only of Foraminifera—is not surprising. 
We now proceed to the description of new species, and notes 
on the more remarkable forms of the Foraminifera occurring in 
the beach-sands of Funafuti.

Mirtonina taBrosa (d’ Orbigny). 
The specimens from Avalau Islet exhibit the same tendency to 
merge into Nubecularia Bradleyz, Millett, by growing irregularly 
in a lateral direction until the milioline character is entirely lost, 
which Millett remarks in his description of the Malay fora- 
minifera *. There are apparently no specimens from Funafuti, 
such as were found in the Malay soundings, which pass into 
Miliolina valvularis (Reuss). 
MILIOLINA AGGLUTINANS (d’Ord.). 
The form which is rather frequent at Avalau Islet partakes of 
the general characters of J. Bosciana (d’Orb.), and might 
perhaps with equal reason be assigned to that species. Millett 
figures a similar example from the Malay Archipelago 7. 
Minroniwa Ferussacit (d’Ord.). 
Probably more than half the number of specimens from 
Funafuti are represented by the flattened costate variety, formed
