198 A.M. Verrill — Comparisons of Coral Faunae. 



Family Stylasteridae Gray. 

 Stylaster, sp. 



Pernambuco, on Mussa Hartlii (R. Rathbun). 



Recorded only by Rathbun, Amer. Nat., xiii, p. 542, 1879. 



Many of the corals in the above list undoubtedly occur on all the 

 principal groups of reefs, from the Roccas, north of Cape St. Roque, 

 to the Abrolhos, but I have given only those particular localities 

 from which I have seen specimens, or from which they have been 

 recorded by Prof. Hartt or Mr. Rathbun. 



The following species of corals, dredged by the Hassler Expedi- 

 tion off the coast of Brazil, in moderate depths, were described by 

 Pourtales (Mem. Mus. Comp. Zool., iv, 1874). None of them are 

 reef-corals :
