﻿APPENDIX TO THE GENUS MONTIPOEA. 



While the foregoing pages were passing through the press, two small collections of Montipores, 

 one from Funafuti, made by Mr. J. Stanley Gardiner, and the other from the Loyalty Islands, 

 made by Mr. Arthur Willey, were kindly sent me by Mr. Gardiner,|of Gonville and Caius 

 College, Cambridge, for inspection, in order that I might be able to incorporate any fresh types 

 in this Catalogue. Their examination has resulted in seven new species, the type specimens 

 of which remarri, thanks to Mr. Gardiner's kind permission, the property of the British 

 Museum. I am also indebted to Mr. Gardiner for the information he has given me regarding 

 the colours of some of these corals when alive. 



a. Foveolate. 



136. Montipora pilosa. 



Description. — Corallum closely encrusting, without free edges, 3 mm. thick. 



Calicles minute, • 3 mm., but comspicuous, because sunk in the hollows between inter- 

 stitial ramparts, margin not circumscribed, irregularly distributed, 1 to 2 mm. apart. Two 

 cycles of septa, irregularly developed. One directive interruptedly laminate, exsert and 

 sometimes continued up the sides of the interstitial rampart. 



Ccenenchyma shows in section a very stout laminate reticulum, resting on the epitheca. 

 The surface rises evenly above the level of the calicles ; the depressions for the calicles are 

 distinct, round and funnel-shaped, about 1 mm. in diameter and • 5 mm. deep. The surface 

 texture consists of very fine iiakes, standing up and twisted in all directions ; to the naked 

 eye it appears soft and hairy. 



There is only one specimen of this coral, a small encrusting patch, 6 cm. across ; its 

 surface is very irregular, owing to the unevenness of the substratum. One side was evidently 

 being killed by other organisms. In general appearance and in its apparently wooUy texture 

 it approaches M. mollis, but on closer comparison the two are seen to differ widely. The 

 calicles of M. mollis are larger, closer together, have much more pronounced septa, and are 

 not so deeply and definitely immersed as they are in this specimen.

* This specimen is further valuable because underneath it are the three earliest known stages 

 in the growth of Alveopora.
