REPORT ON THE REEF-CORALS. Pail 
Of these three species are new :— 
Seriatopora crassa. | Cyphastrea brueggemanna. 
Porites mirabilis. 
Montipora rigida is the most abundant reef-forming species. 
9. SAMBOANGAN. 
Forty-two species of True Corals, representing sixteen genera, and two Hydrocorals, 
were collected. 
“The beach of the island was almost entirely composed of Coral débris. The main 
part of the mass was made up of the lighter, more friable perforated Corals. The 
considerable abundance of Millepora and great quantity of Tubipora was remarkable and 
characteristic. There are no extensive series of reefs about Samboangan, merely fringing 
reefs of small extent. In the full wash of the tide in the channel the shore is sandy and 
1 
muddy and apparently without Corals. 
The species collected comprise the following :—
