132 A. E. Verrill — Bermudimi and West Indian Reef Corals. 



This is not a West Indian species, as some writers have supposed. 

 All specimens that I have seen were from Singapore. 



Several other, apparently distinct species, have been described 

 from the Indo-Pacific region. Among them are the following : — 



IT. aspera Quelch, op. cit., xvi, p. 88, pi. iii, figs. 5-56. Banda. 



IT. cellulosa Quelch, op. cit., p. 87, pi. iii, figs. 6-6c, 1886. Banda. 



IT. maxima Rehberg, Abh. Gel). Xaturw. Yer., Hamburg, xii, p. 

 iS, pi. i, fig. 12, 1892. Duke of York Island. 



IT. Stuhlrnanni Rehb., op. cit., p. 17. Zanzibar. 



Addenda to Favitince. 



The following species should have been inserted on page 91. 



Favia Whitfieldi Ver., sp. nov. 



Plate XXV. Figure 5. 



This coral forms rounded masses, up to four inches (I00 mm ) in 

 diameter. Calicles a little elevated, rather large, 8-12 mm in diameter, 

 mostly nearly circular ; some are elliptical and undergoing fission; a 

 few are irregularly lobed. Their cavities are rather deep, funnel- 

 shaped, narrow at the bottom. 



Septa somewhat exsert, rounded at the summit, and roughly ser- 

 rate ; paliform lobe well developed, serrate. Columella small, lamel- 

 lose or trabecular ; walls thick, solid, separated by dense exotheca 

 having few cellules in one row. 



Nassau, X. P., — coll. R. P. Whitfield. Two good, fresh specimens 

 are in the American Museum Nat. Hist., Xew York. Xo. 540. I 

 have seen other specimens that are beach-worn. 



This species is quite unlike any of the other West Indian species 

 of Favia. Its general appearance, and especially its large, round 

 calicles cause it to resemble some of the East Indian species. Its 

 septa are more roughly serrate than in most species. 



Family Echinoporidae. Emended. 



Coral usually foliaceous or frondose, sometimes branched, rarely 

 encrusting, generally thin, with the exotheca or ccenenchyma spar- 

 ingly developed and usually cellular, but sometimes solid (Acantho- 

 pora). Corallites short, often obliquely appressed ; increasing 

 chiefly by marginal, basal, or intercostal budding, generally scattered 

 irregularly and only on one side of the foliaceous species, but some- 

 times on both sides, and not forming collines, but sometimes 

 arranged in short rows.
