Reports, Zoology, XVI, p. 51.) The species does not appear to have 

 been hitherto observed in the Bermudian waters. 



Oculina coronalis, Queleh. 



Harrington Sound. First described from the Bermudas (Challen- 

 ger Reports, Zoology, XVI, p. 49.) 



Queleh, in his report on the reef-building corals of the Challenger 

 {op. cii., pp. 9 and 49), enumerates as an additional member of the 

 Bermudian fauna the Oculina JBermudiana of Duchassaing and 

 Michelotti. I have been unable to find anything in the description 

 or figures ftirnished by these authors (Supplement au Mhnoire sur 

 lea Coralliaires des Antilles, p. 162, pi. IX, figs. 1, 2 — Memorie 

 della Reale Accad. Seienze di Torino, Ser. Sec, XXIII, 1866) to 

 distinguish their species from Oculina sjyeciosa, nor does it appear 

 to me to be distinct. The characters upon which the form is sep- 

 arated are exceedingly trivial, and well within the amount of 

 variability which is presented by individual specimens of nearly all 

 the species of Oculina. I further believe that 0. coronalis, and 

 possibly also 0. recta, will have to be united with 0. speciosa. 



Isophyllia australis ? Edwards and Haime. 



Three specimens from the North Rock, doubtfully identified with 

 this species. 



Isophyllia fragilis T Dana. 



I am unable to satisfy mj self as to the positive existence of this 

 species in Bermuda, although Queleh refers to a single specimen 

 having been obtained there by the Challenger party. This author- 

 ity doubtfully refers one of the forms figured by Pourtales (op. cit., 

 pi. VII, fig. 3) as I. dipsacea to Dana's species, but from an 

 examination of a number of Bermudian specimens which agree 

 absolutely with Pourtales's figure I am fairly convinced that this 

 identification is incorrect. The specimens do certainly not agree 

 sufiiciently with Dana's description, and if they are not the types of 

 a distinct species, then they represent probably only a certain phase 

 of development of /. dipsacea, as in indicated by Pourtales. 



Isophyllia dipsacea, Dana. 



Three specimens, from Castle Harbor. 



Isophyllia strigosa, Duchai^saing and Michelotti. 



A number of specimens, from Harrington Sound, which agree 

 with the description of this species. I am doubtful as to the species 

 being distinct from Isophyllia dipsacea ; possibly, however, some of
