The specimens from Funafuti agree in most respects with 
those figured by Goés from Novaya Zemlaia and off Newfound- 
land. By a comparison of the chief characters of the tests 
of this species and P. striatopunctata, there seems to be a direct 
affinity between those forms; and it is possible that they 
represent a single species, of which P. subnodosa is the megalo- 
spheric type, with an umbonate centre, and P. striatopunctata the 
microspheric type, with a depressed centre. 
P. subnodosa, as a recent form, has been but rarely found up 
to the present, for, besides the localities mentioned above, it has 
only been found amongst the islands south-west of Papua, at 
depths of from 6 to 28 fathoms.

This is the only species of Foraminifera which was obtained 
from every sample of the lagoon dredgings. It varies in size 
from a diameter of *75 to 3°5 mm. The test is often flexuose on 
the peripheral edge; and towards the middle of the lagoon it 
shows a tendency to make abnormal outgrowths, in beak-like 
processes near the last series of chambers in adult shells, or as 
buds around the oral aperture. The test sometimes shows a 
tendency to become partially attached to alge, at the oral region, 
especially in the deeper parts of the lagoon. 
Lagoon, Funafuti. In samples 1 to 18. Samples 4, 6, and 15 
yielded the finest specimens.
