to be most nearly allied to Alveopora Irevispina, Eeuss,* * * § but in tbe other features to 
A. Tiystrix, Reuss.f If the paired condition of the septa, here so very marked, is a 
constant and definite character, and it appears to bo so, it will at once distinguish this 
coral from all those described by Dr. Eeuss. 
The largest and best-preserved coral is a species of Leptoria, a genus not met 
with either by Reuss amongst the Javan corals, nor by Prof. K. Von Pritsch,J amongst 
those collected in Borneo by Mr. R. D. M. Verheek. On the other hand, Prof. K. 
Martin, of Leiden, describes § an allied genus, Codoria, from the former country. The 
characters of the New Guinea Leptoria, as pourtraycd in the single specimen, are not 
sufficiently clear for specific description, and make one long for further material. 
Leptoria is extensively distributed in the Indian and Pacific Oceans. 
Next in order is a well-marked Galaxea, again only a fragment, hut clearly not 
far removed from the recent G. olavis. The corallum, as preserved, is split in half 
longitudinally, and exhibits several corallites radiating outwards and surrounded by a 
copious peritheca. 
The last to be noted, but certainly not the least important, are two examples, 
fragmentary unfortunately, of the interesting genus Beltocyathus, distinct both 
from the Tertiary and Recent species L. italicus, Ed. and H., and the recent L. 
magnificus, Mosely. The occurrence of this genus in these New Guinea beds is of the 
highest interest, following as it does upon its discovery by the “ Challenger ” Expedition 
in the Pacific. || 
The material presented by Mr. Edelfelt to the Queensland Survey Collection is 
of too limited a nature to permit any definite statement to be made as to the age of the 
beds, but they are either Younger Miocene or Pliocene, probably the latter. The Javan 
series described by both Reuss and Professor Martin are considered by the latter to be 
of Miocene age.^
