78 A. E. Vcrrill — Bermudian and West Indian Beef Corals. 



I have seen the type of Dana's strigosa and consider it this species 

 from personal study of it. The figures published by Pourtales (op. 

 cit., 1880) are excellent. 



Whitfield (op. cit., 1901*) has described and figured an interesting 

 abnormal specimen of this species from the Bahamas, which he 

 thought a case of union between a Ctenophyllia and Mceandrina. 

 But the central part, which he called Ctenophyttia,\s not that genus. 

 It has serrate septa and is only a variation of this Mmandra, in 

 which the ridges and valleys have become unusually wide, the latter 

 varying from about 12 to 15 mm . Similar cases are not rare.

This species is easily distinguished by its narrow actinal grooves 

 and generally simple, solid ridges ; by the crowded septa, alternately 

 larger and smaller, and not rising much above the wall ; by the 

 number of septa to a centimeter, which is 28 to 36, usually about 30; 

 by the narrow, interrupted columella ; and by the nodose, gibbous, 

 or lobulated character of the coral, except when young.

 of Living Corals, Bull. Amer. Mus., xiv, p. 221. I have recently examined this 

 specimen, with Mr. Whitfield.
