600 MESSRS. E. HERON-ALLEN AND A. EARLAND ON 
No. 7. The residue of the prelimin;iry sample from 58.c, dried without heat. This 
material was coarse, and yiehied practically no " floatings," the Pora- 
minifera being a good deal worn. It consisted largely of Orbitoliies 
and Tinoporus [Buculogypsina spluerulata) with about twenty other 
species of robust types, among which Amphistetjwa lessonii, Textularia 
ar/r/lutinans, and its ally Eaddonia torresiensis were prominent. 
Perliaps the most notable feature of the gatherings was the presence of 
two genera new to science, Diffusilina and Craterites, which are fully 
described and figured in this monograph. 
Another verj^ noteworthy and interesting feature was the profuse occur- 
rence of species in the reproductive stages, both by viviparity and " budding." 
We have called attention, in our notes, to Nuhecularia lucifuga, Spirillina 
campainda (sp. nov.), Discorbina tabernacularis, Gypsina iiihcerens, and oihers, 
containing young brood in the cavit}^ of the test, resulting from the absorption 
of the internal septa. Beyond this, certain species (e. g., Bulimina elegan- 
tissima) exhibited unquestionable evidence of the reproduction by " budding " 
from the aperture, described at length and illustrated by Heron-Allen in the 
Phil. Trans, of the Royal Society (H-A. 1915, RPF.). 
Among the 199 species and varieties described from the material sub- 
mitted to us, seven are new to science. Perhaps the most noteworthy 
species, beyond these, are JSuhecularia schauinslandi, Miliolma kerimbatica 
M. stelligera, Fischerbia pellucida, Iridia diaphana, Haddonia torresiensis 
Frond i.cularia scottii, Uvigerina selsegensis, Ramnlina grimaldii, and Discorbina 
reni.formis. 
We may be allowed to say that we have never had material submitted to 
us which has been more carefully collected and preserved for examination. 
Our onlj' regret is that it should have been collected from reefless areas only. 
No complete study of the foraminiferal fauna of the Island can be made 
under such reservation. The material shows that a large proportion of the 
specimens are not of local origin, but are more or less water-worn shells 
which have travelled some distance. The more perfect specimens, of local 
origin, arc, in the case of a number of species, ratlier small and pauperate, 
probably evidencing existence under difficulties, due, no doubt, to paucity of 
food on the exposed side of the Island. A collection made on the eastern 
side of the Island^ among the reefs and in the still waters of .the Lagoon, 
would probably have yielded a much longer list. 
The general facies of the foraminiferal fauna is, of course, sub-tropical 
and of the Indo-Polynesian type. Many of the species recorded have a wide 
range, from East Africa, through the Malay and Australasian Seas, to the 
Pacific. Perhaps the most significant feature is the marked rarity of certain 
genera which might reasonably have been expected to occur in abundance, 
e. g., Hauerina, Peneroplis, Alveolina, Polytrema, Operculina, Heterosteqina, 
and so on, and the entire absence of many typical species which we should 
have expected to find in such latitudes and in such conditions.
