and included in a group called P. Gaimardi by Milne-Edwards and Haime (see above P. Queen 
Charlotte Islands, 1, p. 82). As this latter coral came from Vanikoro, nothing is gained by 
claiming the Mergui form to be of the same species without giving the evidence on which 
that conclusion is based. 
2. A form which Duncan compared with the Red Sea Porites called nodifera by 
Dr. Klunzinger. The description and photographs of the latter author * supply far better 
material for comparison than those of Quoy and Gaimard; we can thus obtain a better 
idea of this coral than we can of No.1. It was from King Island Bay. 
3. This was a ccenenchymatous Porites, also from Elphinstone Island, and compared by 
Duncan with the coral figured by Dr. Klunzinger as Synarea lutea on his pl. v. fig. 29, 
pl. vii. fig. 4. 
One other form was called by Duncan Porites excavata, on the supposition that it is the 
same species as one described under that name by Dr. Verrill from Panama Bay. ‘The latter 
coral, however, appears to have been a Goniopora.

the Map, locality P. 
Description.—The corallum is built up of encrusting layers, 2 mm. or less thick; surface 
smooth or slightly wavy. 
The calicles are 1 to 1°5 mm., always polygonal and mostly hexagonal. The walls are 
conspicuous, sharp-ridged, porous, faintly granulated. There are twelve septa, and five to six 
well-developed pali, with a variously developed but smaller columellar tubercle. 
The photograph of this specimen hardly gives enough detail to admit of closer description. 
No encrusting forms have yet been recorded from the coasts of Java, although there are 
doubtless many.

Description.—The corallum rises from a small encrusting base with thin, free, or pendent 
edges into a tuft of tall, sharp, smooth, round spikes, sometimes 20 cm. long, wavy, tapering
