This appears to be a rare species. Although it was not collected in either the 

 Cocos-Keeling Islands or at Murray Island, as it has been necessary to discuss it 

 (see page ii8), notes will be made on its distribution. 



Distribution. — Fiji Islands (Dana's type, No. 62, U. S. Nat. Mus.); southern 

 Philippines (J. B. Steere, collector), a smgle specimen in the U. S. National Museum. 

 Gardiner reports it from Wakaya, Fiji Islands. 



Genus M./EANDRA Oken.

 1902. Maandra Verrill, Trans. Conn. Acad. Arts and Sci., vol. II, p. 66. 



Type species: Madrepora labyrinthiformis Linnaeus. 



The species here considered all belong to the section of the genus to which 

 Milne Edwards and Haime applied the name Cceloria. 



Rehberg has described three supposedly new species from Australia, viz: 

 Cceloria elegans, from near Rockhampton; C. deltoides, from Port Bowen; and C. 

 australiensis, from near Rockhampton.^ Until his types have been restudied it is 

 not possible to know with what species he was dealing. However, it seems that 

 his C. elegans and C. deltoides are synonyms oi Mceandra {Cceloria) lamellina Ehren- 

 berg; and although his figure of C. australiensis suggests a fungid coral of the Pavona 

 varians group, it may be related to Mceandra {Cceloria) stricta (M. Edw. and H.). 



Maeandra daedalea (Ellis and Solander).

 do'dalea. Also plate 14, figure 20, of Dr. Mayer's article.

 1907. Cceloria dadatea Bedot, Madreporaires d'Amboine, p. 117, plate 16, figs. 70-72. 



Identification is based on a photograph of the type of Ellis and Solander, fur- 

 nished by Professor J. Graham Kerr. 



Stations, Murray Island. — Southeast reef, line I, i,6oo feet from shore, water 

 10 inches deep (see plate 44, figs. 3, T,a). The series average shorter than usual, 

 most of them less than 17 mm. long, but one is 29.5 mm. long; width of valleys 5 

 to 6 mm.; upper part of wall with some perforations. Also, from 1,632 feet from 

 shore, water 14 inches deep at lowest tide, hard rocky bottom. This is a small, 

 either young or stunted specimen, with much-thickened walls, up to 25 mm. (see Dr. 

 Mayer's No. 20). 



Distribution. — Indian Ocean and eastward in the Pacific to tlie Paumotus 

 (Fakarava, Albatross, 1899-1900).

The following is a description of a specimen of the species from Murray Island: 



Corallum forming massive, rounded heads. 



Valleys long and winding; width 4.5 to 6 mm.; depth, 4 to 4.5 mm. Walls thin, with 

 occasional perforations, or thickened up to 2 mm.
