like, tapering, and sharpened off to a point at the extremity. 

 Minute upright conico-subdeltoid spines are irregularly scattered 

 on the ultimate branchlets, the other parts of the corallum being 

 spineless (fig. III. 3, p. 823). Polyps'pale red, with six tentacles. 

 The remains of the ccenenchyma and polyps are seen on the speci- 

 men as a brown pellicle coating the finer branches, and extending 

 as a thin web or film from branch to branch.

Leiopathes cxpama, sp. n. About I nat. size. From a photograph. 



The only specimen of this new species that I have met with 

 was obtained from a fisherman twenty years ago. It is without 

 a base, and has a height of 405 millim. (16 in.), with a spread of 

 380 millim. (15 in.), but its spread when perfect was probably not 

 less than 445 millim. (174 in.). The thickest part of the stem 

 is only 5 millim. in diameter. 



No fusion of branches is anywhere visible. The elegant flabel- 

 late form and delicate habit seem to distinguish this sufficiently 

 from known species of Leiopathes. 



Hah. Madeira.
