REPORT ON THE REEF-CORALS. 95 
4, Celoria leptoticha, Klunzinger. 
Celoria leptoticha, Klunzinger, Cor. roth. Meer., iii. p. 19, pl. ii. fig. 7. 
A very large specimen in the collection differs from the description given by Klun- 
zinger only in having a well-developed columella. The calicinal series are usually long 
and sinuous, but many single calicles are scattered among them. The wide and deep 
interseptal spaces on each side of the columella are very conspicuous. The walls are 
often broken through and are at times vesicular. 
The Caloria spongiosa (Dana) from the West Indies (2) is close to this species and 
appears to be distinguished only by the greater width and depth of the valleys. 
Locality.—Tongatabu. 
Genus 17. Hydnophora, Fischer, 
Hydnophora, Milne-Edwards and Haime, Cor., ii. p, 418. 
Fr Duncan, Rev, Madrep., p. 97. 
This name was apparently first applied to this genus by Fischer de Waldheim. ! 
Three species were obtained. 
1. Hydnophora microcona (Lamarck). 
Monticularia microconus, Lamarck, Hist. Anim. sans Vert., ii. p. 251, 1816. 
Hydnophora microcona, Milne-Edwards and Haime, Cor., ii. p. 423 
Several specimens of this common species were obtained. 
On many parts of one and the same specimen there are considerable differences in the 
size and number of the septa, and also in the height and thickness of the monticules, 
which are sometimes swollen at the apex. 
Localities —Kandayu and other reefs, Fiji. 
2. Hydnophora demidoffi, Fischer. 
Hydnophora demidofi, Fischer, Mus. Demidoff, iii. p. 295, pl. iv. 
Fe 53 Fischer, Oryct. du Gouvern. de Moscou, p. 156, pl. xxxii. 
The reference to the former work quoted is given by Fischer in the second, in which 
there is a very good figure of the species. 
The specimen in the collection is a small one, and it has grown incrusting as a thin 
lamina over a foreign body. Its margin is free to a greater or less extent, but is not 
turned up. The little cones are much elevated, angular and sharp. 
Locality. —Banda.
