176 THE VOYAGE OF H.M.S. CHALLENGER. 
13. Montipora grandifolia (Dana). 
Manopora grandifolia, Dana, Zoophytes, p. 499, pl. xlv. fig. 1. 
Two fragments were obtained. The specimen was evidently of small growth, the 
fronds being scarcely 5 em. high, with a thickened base by which they were attached. 
The small, crowded, short cells cover almost the entire outer surface, except for a very 
short distance from the upper edge. 
Locality.—Api, New Hebrides. 
14. Montipora papillosa (Lamarck). 
Agaricia papillosa, Lamarck, Hist. Anim. sans Vert., i. p. 243, 1816. 
Montipora papillosa, Milne-Edwards and Haime, Cor., ili. p. 216, pl. E 3, fig. 2. 
A small incrusting specimen of this species was obtained. The longitudinal series of 
papilla are very distinct, but at times they are very small and angular, not thick and 
rounded. 
Locality.—Tahiti. 
15. Montipora verrucosa (Lamarck). 
Porites verrucosa, Lamarck, Hist. Anim. sans Vert., ii. p. 271, 1816. 
Montipora verrucosa, Milne-Edwards and Haime, Cor., iii. p. 214. 
A few small specimens were obtained. The species, apparently, may assume a 
branched form, for in one specimen a small branch has developed on one of the 
gibbosities. The comparatively large, open, deep cells, with the alternately large and 
small septa meeting at the bottom of the cell, will serve to distinguish this species from 
Montipora capitata (Dana). 
Locality.—Reefs, Honolulu, and from depths of 1 to 2 fathoms. 
16. Montipora capitata (Dana). 
Manopora capitata, Dana, Zoophytes, p. 504, pl. xlvii. fig. 4. 
Small specimens of this species were obtained. Though very close to Montipora 
verrucosa, it seems to be sutticiently distinguished by its decidedly branched form, its 
smaller cells, and the broader septa, which tend to fill up the cavity of the cell, as well 
as by the thinner, closer, and more unequal tubercles of the surface. 
Locality.—Reefs, Honolulu, and from depths of 1 to 40 fathoms. 
17. Montipora foveolata (Dana). 
Manopora foveolata, Dana, Zoophytes. p. 507. 
The walls of the calicles in this species are very finely porous, often much thickened, 
and frequently, at the angles of the calicles, they are much and sharply elevated. The
