As so little lias been -written about the coral fauna of the seas 

 ■within the limits of the Indian peninsulas, the following account of the 

 corals dredged in recent years by the " Investigator," and by the late 

 Professor Wood-Mason, may be of interest. 



No reference is made in this paper to the true reef -forming corals. 



FAMILY TURBINOLID^. 

 Flabellum, Lesson. 



1. Flabellum stokesi, Edw. & Haime, Moseley. 



Flabellum stolcesi, Flabellum oioeni, Flabellum aculeahim, Flabelhim 



sum, all of Milne-Edwards and Haime, Hist. Nat. des Coralliaires, 

 vol. ii. pp. 96, 87 and 88. 



Flabellum variabile, Semper, Z. Wiss. Zool., vol. xxii, 1872, p. 245. 



Flabellum stohesi, Moseley, Challenger Deep-sea Madreporaria, 

 p. 172. 



This species, not hitherto recorded in the Indian Fauna, is com- 

 mon from Ceylon, along the east coast of India, to the Andaman Islands, 

 at depths of from 20 to 30 fathoms. The numerous specimens dredged 

 I . Professor Wood-Mason in the Andaman Sea, and by the " Investi- 

 ; ' elsewhere, fully bear out Professor Seraper's views as to the 

 identity of all the four species of MM. Milne-Edwards and Haime 

 above-cited. Undoubtedly Professor Semper's name for the species is 

 very appropriate ; but, as Professor Moseley says, it is necessary to 

 retain, one of the original names, and he has selected the specific de- 

 signation stokesi as being least likely to lead to error. 



Acanthocyathus, Edw. & Haime. 



2. Acanthocyathus grayi, Edw. & Haime. 



Acanthocyathus grayi, Milne-Edwards and Haime, Hist. Nat. des 

 Corall.. vol. ii. p. 22. 



This species was described by MM. Milne-Edwards and Haime as 

 of " patrie inconnue :" I have little hesitation in identifying with it a 

 single specimen dredged by Professor Wood-Mason in the Andaman 

 Sea.
