MADREPORA. 83 



Family STYLASTERIDiE Gray. 



STYLASTER Gray. 

 Stylaster sanguineus ? Val. 



Three specimens of a Stylaster from Florida in the Museum of Com- 

 parative Zoology, labelled and catalogued as Stylmier roseus, cannot be 

 distinguished from a specimen from New Zealand, which agrees with 

 the description and figure of SL sanguineus Val., in the Monograph of 

 the Oculinidje by Milne-Edwards and Haime, in Amiales des Sciences 

 Natiirelles. 



Another specimen from Florida is kept in the Museum of Yale Col- 

 lege in New Haven, as I am informed by Professor Verrill. The depth 

 from which it was obtained is not stated, but it must be from compara- 

 tively shallow water, as it was obtained by parties not provided with 

 dredges. I have never found it myself. I have marked it doubtful as 

 to its specific identification, on account of the very distant habitat of 

 the specimens originally described. This is the species mentioned as 

 St. roseus Gray, in Bull. Mus. Comp. ZooL, No. 3. The latter is abun- 

 dant on the under surface of blocks of coral rock, on the reef at Cruz 

 del Padre, north coast of Cuba, a couple of feet below low-water mark. 

 It is not found on the Florida Reefs. 



Family MADREPORIDiE Dana. 



For reasons stated elsewhere, the Eupsammidse ought to be excluded 

 from this family, the limits of which would be thus nearly those estab- 

 lished by Dana ; the proper position of the Montiporae (Manopone 

 Dana) still requires investigation. 



MADREPORA Linn, [pars), 



Madrepora palmata Lamk. 



Madrepora Jlabellum Lamk. 

 Madrepora alces Dana. 

 Madrepora cornuta DucH. & MiCii. 

 Madrepora Tliomasiana ? Duch. & Mich. 



The conclusion arrived at from the comparison of a large number of 

 specimens, of all ages and sizes, is the specific identity of Maeb'cpora
