REPORT ON THE REEF-CORALS. 97 
The trabeculate columella is often very small, situated at the bottom of a narrow central 
depression, surrounded by the paliform lobes. 
Locality.—Mactan Island, Philippines. 
2. Astrea pandanus, Dana. 
Astrea pandanus, Dana, Zoophytes, p. 222, pl. xi. fig. 2. 
The specimen in the collection is smail and convex. The calicles are remote at the 
outer part of the colony, with a broad furrow; the septa are of four cycles, the third 
being very small and narrow, and the fourth quite rudimentary, and represented 
generally only by one order; the paliform lobes are more or less distinct and acute. 
Locality.—Banda. 
3. Astrea versipora, Dana. 
Astrea versipora, Dana, Zoophytes, p. 233, pl. xii. fig. 5. 
At the central part of the corallum the cells are often incompletely sulcate, and the 
ridges quite narrow; the paliform lobes are very indistinctly marked and often absent ; 
the septa are quite thin within, very unequal and thickened at the wall, and rough and 
raggedly exsert. A single specimen was obtained. 
The Astra versipora, originally described by Lamarck, is referable to the genus 
Plesiastrea ; but it seems advisable to retain the name given by Dana to this present 
form,.even though his identification of it with that of Lamarck was at fault, since it 
belongs to a genus different from that of the original description. 
Locality.—Kandavu, Fiji. 
4, Astrxa dane (Milne-Edwards and Haime).

Astrxa danx, Verrill, in Dana, Cor. and Cor. Islands, p. 329. 
The interealicinal spaces are much broader and more distinctly sulcate at the outer 
part of the corallum than within. The cups are often elongated and irregular. 
A single small specimen was obtained. 
Locality.—Reefs, Fiji. 
5. Astrea ordinata, Verrill. 
Astrxa ordinata, Verrill, Proce. Essex Inst., vol. v. pt. 3, p. 34. 
A single small specimen is referable to this species. As Verrill observes, it is closely 
allied to the Astrwa speciosa, Dana, but scems sutliciently distinguished by its firmer
