 Oculina Pcfn-eri IM.-Knw. & H. 



As pointed out. by Mr. '\'eiTill (]>u]]. Mas. Comp. Zoul., No. 3). this 

 species is entirely difierent from (). dilfiixa, of which M.-Edwiinls iind 

 Haime had supposed it to be a synoinine. Lesueiu-'s descri|)ti<)ii iind 

 figure are quite insuflficient to determine if he really had tiiis 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 develojjcd state, to my 

 knowledge. I have I'eferred to it some branchlets which I had at fiist 

 described as OciiUiia di-s/ic//u (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 Oculina pulkm, Ehrbg., Dana, 

 which is certainly not synonymous with O. ilijj'vm, as supposed by M.- 

 Edwards and Haime. 



Oculina robusta Pourt. 



Corallum sparsely liranching ; 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, foruiingmore or less regular 

 spiral lines. Three cycles; prinuiry and secondary si>])ta al)()ut e(|ual, 

 tertiaries but slightly smaller. Pali small, ])ointed, not \i^'\-\ difierent 

 from the columellar ])apiilai, whicli are very nunu'rous. Costal stria> well 

 marked, nnich curved, broad and Hat, delicately granulated. 



One specimen (No. S")7) in the Museum was received from Dr. 

 Holder at Tortugas, Florida, to whom the ^luscnin is also iruU'btcd I'or 

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

 Agassiz that there is another (ine s])ecinien in the New York Free 

 Academy, from the sanu- locality. 



Ociiliiui tirhui<ci\l<i and Ocitlina iiiiji/lculd. ^\g. Ms. (Vcri'ill, IJull. Mu.<- 

 Comj). Zo()l. No. 3) are not found in the reef region. The former is 

 conunon on the coasts of North and South Caiolina, and its northern 

 limit is ])r()bal)ly Cajjc Hal (eras. 'I'he second is only known from 

 s])t'eimeus thrown up on the lieaches of Nortli Carolina, and has a .semi- 

 fossil appearance.
