CLADOCORACE.SJ M.-Edw. & H. 

 CLADOCORA M.-Edw. & H. 



Cladocora (pars) Ehrbg. & Hemp. 



Cladocora debilis M.-Edw. & II. 



Specimens of a Cladocora somewhat different from C. arbuscula, 

 common in shoal water, are referred to this species. They are 

 slenderer, less branching, have a more shallow fossa, well-developed 

 pali and columella, and more exsert septa. 



Off Sand Key, in 26 fathoms. 

 Off French Reef, in 45 fathoms. 

 Off Elbow Reef, in 49 fathoms. 

 Off Carvsfort Reef, in C3 fathoms. 



Cladocora arbuscula, as far as my observations go, is found from low- 

 water mark to 13 fathoms. It is possible that Cladocora debiUs may 

 be merely a deeper water variety of this species.

Off Double-IIeaded Shot Key (Elbow Key), in 315 fathoms. 



Dead specimens, rather worn, were dredged up with quite a number 

 of other dead corals at this [dace, shoal-water and deep-water species 

 being mixed together. The locality is very near the edge of the 

 Salt Key Bank, at the foot of a very steep submarine slope, and 

 washed by the edge of the Gulf Stream.
