 fms. ; temperature at 600 fms., 8'22 C. ; 12th Sep- 

 tember, 1907. Six specimens. 



Of this species, now taken for the first time within the Irish 

 area, seven well-preserved specimens of various sizes were 

 obtained. The remaining five specimens are in a very worn 

 condition, some of them having the septa almost entirely 

 rubbed away. The largest fresh specimen reaches a length of 

 50 mm. The longer diameter of its calyx is 30 mm., and the 

 shorter diameter 25 mm. 



The geographical distribution of D esmophyllum crista galli 

 is very wide. It has been taken off both the eastern and 

 western shores of the North Atlantic, off Patagonia (as D. 

 ing ens, Moseley), in the Indian Ocean, and in the Pacific 

 Ocean off the west coast of Panama, off the Hawaiian Islands, 

 and off the East Indies.

Many fragments of this coral, both living and dead, have 

 been obtained at the above localities. This species was first 

 taken off the west and south-west coasts of Ireland by the 

 Porcupine expedition of 1869-1870. More recently it was 

 found off the Kerry coast by the Eoyal Dublin Society's Sur- 

 vey of the west coast of Ireland in 1890-1891. 



Lophohelia prolifera has been dredged many times in various 

 parts of the North Atlantic. It also occurs in the South 

 Atlantic and in the Indian Ocean.
