p. 47, footnote) suggested that another of Savigny's splendid figures, Porites " clavata Aud." • 

 the mysterious coral on pi. iv. fig. 6 of the Description of Egypt, was also a Goniopora (see 

 below, p. 99). 



It has further to be noted that Dr. Klunzinger, who refers several times to Bnlggemann's 

 paper quoted above, rejects the criticism of that writer and reaffirms that the deeper calicles are 

 the older, and the shallower lateral calicles are the younger. 



In 1878, Professor Studerf adhered to the classification of Milne-Edwards and Haime 

 He described no new " species " but recorded " G. pedunmlata Q. & G." from the Solomc 

 Islands, and " G. columna Dana " as plentiful in Holzhafen, New Ireland. 



In 1884, Martin Duncan's % revision of Milne-Edwards and Haime's system of Madre- 

 poraria contained no essential change in the position of the genus. It was said to differ on 

 the one hand from Rhodarcea in having " no pali " and endotheca, and on the other from the 

 fossil genus Litharcea in the feeble development of the septa. These three genera beginning 

 with Rhodarcea lead on, with the intervention of the fossil genus Protarcea§ M.-E. & H., 

 to Alveopora.^ 



In 1886, Mr. Quelch in his 'Challenger' Eeport on the Eeef Corals, placed Goniopora as the 

 fourth genus of the Poritidce. Only three representatives of the genus were discovered by the 

 Expedition and these were named Goniopora pedunculata (see below, p. 70 and p. 37), 

 Rhodarcea tenuidens (see below, p. 69 and p. 15), and the third was thought to be a type of a 

 new genus Tichopora (on this see p. 16). 



In 1888, Dr. Ortmann || described a new "species" G. parvistclla and placed the genus 

 after Rhodarcea and before Alveopora, thus accepting the usual position assigned to it among 

 the Poritidse. In his later work on the classification and phylogeny of the Stony Corals 1T 

 the genus was not referred to. 



In 1891, Mr. Saville-Kent ** described and figured a new and previously quite unknown 

 form, viz. one with thin branches, as " Goniopora fruticosa " ; but in 1893, in 'The Great 

 Barrier Eeef,' he preferred to call it " Rhodarcea fruticosa." He further called attention to the 

 remarkable variety of colour displayed by the polyps. 



In 1896, Miss Ogilvie ft followed Milne-Edwards and Haime in the place assigned to the 

 genus, but did not discuss it apart from the family. In the same year, Dr. G. v. Koch %% 

 figured the structure of the skeleton of a " G. molluccensis " ( = ? G. malaccensis Briig.) showing 

 a simple wall. 



In 1898, in discussing the relationship between this genus and Alveopora, the present 

 writer §§ analysed its so-called trabecular structure, and showed that its " trabecules " could
