A. E. Verrill — Bermudian and West Indian. lieef Corals. 118 



in 1878. Under this name he induflecl the whole extensive genus. 

 This name would surely be a very inappropriate one, so far as its 

 significance is concerned, nor would Studer's definition apply to the 

 genus, as a whole. Moreover, it may become necessary to separate 

 Isopora, in Studer's sense, as a genus. I believe that Acropoi'a 

 Oken has much better claims for adoption in place of Madrepora. 

 (See below.) 



As restricted above, the geinis will include branching oculinoid 

 corals that increase by lateral or marginal buds ; with turbinate 

 corallites, and deep cup-like calicles. The coenenchyma is usually 

 abundant and solid in the main branches and trunk, but may be 

 very scanty in the terminal branches. Pali lacking. Septa broad, 

 entire. Columella small or lacking. 



Besides the type and 31. virginea (L.), which is considered identi- 

 cal with it by Edw. and Haime, the genus Madrepora., as restricted 

 above, would include the following species and others: 



M. veniista E. and H., Australia. 



M. exigua (Pourt., as Lophohelia). Off Florida, 36-79 fathoms. 



M. Carolina (Pourt., as Lophohelia). Off Havana. 



M. prolifera (L.). Boreal and Arctic, and in deep waterto Florida. 



M. infundibuliferaYoiVd. (as Oculina). Kent, fig., 1871 ; Quelch,

31. subcostata (Edw. and H.). Locality unknown. 



Jif. Defrancei (E. and H.). Pliocene of Europe. 



31. Candida (Moseley, 1881, as Lophohelia). Off Sombrero I., 450 

 fathoms. 



31. tenuis (Moseley, 1881, as Lophohelia). Philippine Is.

 or astreiform, increasing chiefly by fission, complete or incomplete. 

 Septa entire or nearly so, sometimes very finely serrulate. Pali- 

 form lobe, feeble or lacking. Columella variously developed, often 

 lacking. Zooids actiniform, much exsert in expansion.
