INDIAN OCEAN PORITES. 195 
No. 905. 
[“ From top of 1st Inland Cliff, South of the Waterfall.” 
Syn. Porites belli (pars) Gregory, 1. ¢. 
The specimen is much altered, with tendency of the calicles to be weathered out. The 
special feature is the small size of the calicles, rather under than over 1 mm. (Cf. the recent 
Porites Christmas Islands 1 (p. 190). No distinct plan of the original skeleton can now be 
seen, but stray traces here and there show for certain that the walls were thin, and composed 
of single threads. There is an appearance as if the skeleton had been hollowed out by some 
foreign organism, as is the case with so many stony corals. 
The single specimen is cut in two.

‘[ Lower part of Sea Cliff. ] 
Syn. Porites aff. lutea (partim) Gregory, 1. c. 
The skeleton is traceable in the section, and seems to show another phase of the 
deposition of matter upon the original skeletal framework, so as in this case to fill up the 
cavities. The walls were thin and thread-like, and the specimen thus seems rather to belong 
to the group “ P. belli” of Professor Gregory, than to “ P. aff. lutea,” in which it is placed in 
his paper (1. ¢.). 
There are three portions of the specimen, and one microscopic slide.

[Inland Cliff, altitude 250 feet. | 
Over the greater part of this specimen only the walls persist, and their thread-like character 
can be easily made out. 
The block is cut in two halves.

No, 128 and No. 358. 
[? exact localities. ] 
Two more specimens, the latter of which comes nearest in general appearance and 
internal character to No. 609. In No, 128, the original texture has almost entirely 
disappeared. 
In all, four fragments. 
S-9. ; Geol. Dept. R. 3756, and R. 3747. 
There are other fragments, as to which it is impossible to say whether they are or are not 
representatives of this genus.
