the living colony is a brownish black, that of the cleaned corallum 

 brown. 



The species is nearly related to P. lichen (Dana) and P. echinu- 

 lata (Klimzinger), but the arrangement of its septa and columella 

 is quite distinct. 



In addition to those mentioned above I have fragments, which 

 I believe to be referable to P. yaimardi ("Wakava, Fiji), P. tenuis 

 (Eotuma\ P. favosa (Wakaya, Fiji), and P. crihrijjora (Eotuma), 

 although all of them exhibit considerable variations : three others, 

 all from Funafuti, seem referable to new species. Of the latter 

 I find no authentically named specimens in the British Museum, 

 but it does not seem to me advisable to make types of mere 

 fragmentary specimens, on which the variations cannot be properly 

 studied.

(Plate XXV.) 



Among the larger Mammals of Asia, the Banting is one of those 

 in regard to which our information is most deficient — the British 

 Musetun, in addition to skulls, possessing but three specimens, 

 while only a single living example has been exhibited in the 

 Society's Menagerie.
