66 OCULINA. 



Oculina varicosa Lesdedr. 



Madrepora mammillaris Ellis ? 

 Oculina varicosa Dana. 

 Oculina Pelieeri M.-Edw. >V II. 



As pointed out by Mr. Verrill (Bull. Mus. Comp. Zool., Xo. 3), this 

 species is entirely different from 0. diffusa, of which M.-Edwards and 

 Haime had supposed il to be a synonyme. Lesueur's description and 

 figure are quite insufficient to determine if he really had this species 

 before him ; it has been, in point of fact, first described by Dana. 



It has not yet been found in Florida in a fully developed state, to my 

 knowledge. I have referred to it some branchlets which I had at first 

 described as Oculina disticka (see Deep-Sea Corals, p. 22 |, dredged off the 

 Reef. The Museum possesses fine specimens from Bermuda ; it has 

 also from the same locality specimens of Oculiun pallens, Ehrbg., Dana, 

 which is certainly not synonymous with 0. diffusa, as supposed by M.- 

 Edwards and Haime. 



Oculina robusta Podrt. 



Corallum sparsely branching; trunk rather massive (3 to 4 cm. in 

 diameter). Calicles numerous, about 3.5 mm. in diameter and about the 

 same distance apart, with prominent border, forming more or less regular 

 spiral lines. Three cycles; primary and secondary septa about equal; 

 tertiaries but slightly smaller. Pali small, pointed, not very different 

 from the columella! papillae, which are very numerous. Costal stria 1 well 

 marked, much curved, broad and fiat, delicately granulated. 



One specimen (Xo. 857) in the Museum was received from Dr. 

 Holder at Tortugas, Florida, to whom the Museum is also indebted for 

 a fine series of corals from that vicinity. 1 am informed by Mr. A. 

 Agassi/, that there is another fine specimen in the New York Free 

 Academy, from the same locality. 



Oculina arbuscula and Oculina implicala, Ag. Ms. (Verrill. Bull. Mus- 

 Comp. Zool. Xo. 3) are not found in the reef region. The former is 

 common on the coasts of North and South Carolina, and its northern 

 limit is probably Cape Hatteras. The second is only known from 

 specimens thrown up on the beaches of North Carolina, and has a semi- 

 fossil appearance.
