POLYNESIAN PORITES. 81 
the Quoy and Gaimard Collection. I have described this, though unfortunately without 
figures, on p. 34. 
3. A form resembling the Porites lobata of Dana, which was from the Sandwich Islands, 
and with characters which are not at all clear from Dana’s description. See below, p. 100. 
4. A coenenchymatous form resembling P. Fiji Islands 5. 
5. Three specimens presumably characterised by great numbers of double calicles. This 
was made a specific character by Mr. Quelch, a ‘ Challenger’ specimen being called on that 
account Porites mirabilis. We do not know what are the causes of these double calicles, 
but they are very common. Their presence in large numbers should, I think, be regarded 
more as a physiological accident than as a morphological character. 
6. Two specimens said to resemble the coral called Porites Gaimardi by Milne-Edwards 
and Haime. This has been described on p. 90, from what appears to be the original specimen, 
preserved in the Paris Museum (Z 1882). 
7. A ccenenchymatous form resembling the Synarwa undulata of Klunzinger. See below, 
P. Red Sea 4. This is certainly quite different from any of the forms here recorded in detail. 
It is clear that none of the above forms, so inadequately recorded, can be utilised with 
any advantage in this work. It is greatly to be wished that any which are clearly different 
in kind from the seventeen apparently distinct forms above shown to occur at Funafuti should 
as soon as possible be fully described and adequately illustrated. 
NEW HEBRIDES. 
57. Porites New Hebrides qyl, (P. Nova Hebridiana prima.) (Pl. VIII. fig. 1.) 
[Api., coll. H.M.S. ‘Challenger’; British Museum. | 
Syn. Porites parvistellata Quelch, Chall. Rep. xvi. (1886) p. 184, pl. xi. figs. 8, 8a (non Gardiner, 
see P, Ellice Islands 10, p. 73.) 
Description—The corallum rises into steeply convex almost ovate masses, the surface 
slightly convoluted with shallow sulci. The living layer extends 4-5 cm. downwards, with 
creeping edges closely adherent. 
The calicles are small, under 1 mm., crowded, deep and angular, the walls are thin, tall, 
membranous, and irregularly porous ; seen from above as smooth, stout, straight threads, but from 
the side with irregular denticulations. Here and there parts of an inner synapticular wall 
are developed. On the lower sides of the stock the walls may thicken and become reticular. 
The septa, which are thin and distinct, may commence to project from the top edge of the wall 
but they meet lower down to form the pali, only the four principals of which can be seen. 
Where the walls are thicker the pali may reach the level of the surface. The fossa is neatly 
circular and deep, but not conspicuous.
