in the broad ridged varieties. Very good figures of the species are given in the Report on 
the Florida Reefs, plate ix. figs. 6 to 9, but they have been taken from a variety in which 
the ridges are more or less triangular, an approach to which is present in “ form f-”

Celoria has been considered a subgenus of Mxandrina by Professor Duncan, but, 
as defined and limited by him, it seems to me sufficiently characterised to rank as a 
distinct genus. 
Four species of the genus were collected. 
1. Celoria dedalina (Dana). 
Astrea dedalina, Dana, Zoophytes, p. 236, pl. xii. fig. 7. 
Celoria dxdalina, Verrill, in Dana, Coral and Coral Islands, p. 329. 
This species is very close to Celoria espert, which will most likely have to be united 
with it. It seems to be distinguished by its thicker, rougher, and more uneven septa, 
and by its shorter calicinal series, but these are very variable characters. In not a few 
parts of the corallum all the ecalicles are in very short series or single, and take on a very 
distinct astraeiform appearance. 
Two specimens were collected. 
Localities.—Kandavu and other reefs, Fiji. 
2. Caeloria esperi, Milne-Edwards and Haime.

A broken specimen in the collection shows well the characters of this species. The 
wall is not vesicular but solid, often becoming slightly swollen towards the outer part of 
the colony. 
Locality.—Kandavu. 
3. Caloria stricta, Milne-Edwards and Haime. 
Celoria stricta, Milne-Edwards and Haime, Cor., i. p. 417. 
A small specimen of this species was obtained. The depth of the calicinal valleys in 
many parts of the corallum is often much less than their width. 
Locality.—Kandavu.
