62 PERCY SLADEN TRUST EXPEDITION 



remaining three have much larger corallites, usually compressed or distorted, which 

 Klunzinger later referred to G. irregularis, Ed. and H. Resembling these latter are two 

 of the "Gazelle" specimens referred by Studer to G. fascicularis. The large examples 

 Studer referred to G. cespitosa, Dana, have corallites of the same shape and size as in my 

 figured type, but the septa are rougher. 



Marenzeller has named twenty-one specimens of the "Pola" expedition G. irregu- 

 laris, of which eight are numbered. No. 15898 resembles my type in every respect; 

 in the remaining ones the corallites are larger and distorted. In one of the unnumbered 

 specimens from Massawah some of the corallites are exactly as in my figure, while others 

 have the irregularis facies. 



In the Copenhagen Museum is a single rubbed specimen, doubtfully regarded as 

 Forskal's original of Madrepora divergens ; its characters are beyond recognition. 

 Ellis and Solander's figured type of Madi-epora fascicularis is missing from the Glasgow 

 University Museum, but their figure resembles my specimens from the Red Sea. 



Quelch's type of G. aspera from Amboina measures 9x6x9 cm. ; a fifth septal cycle 

 is wanting in the corallites, while the fourth is incomplete, but these dififerences are to be 

 attributed to the smallness of the specimen. His example of G. ellisii, Ed. and H., from 

 Mactan Island, Philippines, has somewhat the irregidaris facies, many of the corallites 

 being laterally compressed, with 15 — 17 septa meeting the columella. The place of his 

 type (9x8x5 cm.) of G. fragilis from Amboina is more doubtful ; its corallites are 

 smaller and thinner (both walls and septa) than in his type of G. aspera, but are wider 

 apart, perithecal vesicles larger, costse prominent and sides of septa rough. 



A specimen (10x7x7 cm.) from Ponape, named Galaxea tenella, Briigg., sent from 

 the Hamburg Museum, and now in the British Museum, is perhaps only a variety of 

 G. fascicularis ; the corallites are close together, the septa in five cycles (fifth incomplete), 

 up to eighteen meeting the columella. 



Localities. Red Sea (8 large, some with the irregularis facies and a few small ones). 

 Aldabra, Lagoon Reef (6, mostly with the irregularis facies). Saya de Malha (1, with the 

 irregularis facies from 26 fms.). Also from Seychelles (Milne Edwards and Haime), 

 Fiji Islands (Dana), Amboina and Philippines (Quelch), Ponape (Briiggemann), loc. ? (Ellis 

 and Solander), China Seas (Esper).
