Cladocora debilis M.-Edw. iV II. 



Specimens of a Cladocora somewhat (liHerent from C. arljitxcula, 

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

 slenderer, less ))ranching, have a more shallow fossa, well-developed 

 pali and colnmella, and moi'e exsert septa.

 OffFiencli Reef, in -1.5 fathoms. 

 Off Elbow Reef in 49 fathoms. 

 Off Cirvsfoi't Reef, in (i3 fathoms. 



Cladocora arhmcula, as far as my observations go. is fonnd from low- 

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

 be merely a deeper water variety of this species.

Off Donble-Headed Shot Key (ElboAV Key), in 31 o fatiioms. 



Dead specimens, rather worn, were dredged up with c|uite a number 

 of other dead corals at this place, 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 sIojjc, and 

 washed by the ed"-e of the Ciulf Stream.
