59. GORGONIA ANGUICULUS. (Dana.} Fulvous; ramose dichoto- 

 mous; branches terete, branchlets one and a half to two lines thick, 

 long ; surface scarcely smooth, a little pitted ; oscules very much 

 crowded, nearly circular, quite small ; axis fuscous, of the branchlets, 

 very slender ; axils compressed. 



West Indies. 



This species is rather more slender than the vermiculata, and has 

 very much smaller and more numerous oscules. The branches, 

 although terete and without verrucas, have a slightly and minutely 

 uneven surface, owing to the fact that the oscules are either situated 

 in a slight depression of the cortex, or have the inferior side a little 

 prominent. The length of the branchlets is often six inches. One 

 specimen seen by the author had a dull fulvous colour, and another 

 was purplish.

60. GORGONIA OLIVACEA. (Lamouroux.} Lamarck. Much branched ; 

 branches scattered or subpinnate; branchlets one to one and a half 

 lines thick; cortex thick, olivaceous, oscules scattered.

61. GORGONIA QUINCUNCIALIS. (Ehrenberg.} Dana. Dark ash or 

 reddish; two feet high; dichotomously branched, branches suberect, 

 flexuous, crowded, one and a half lines thick at summits, terete; sur- 

 face a little verrucose (and therefore rough), verrucee appressed, open- 

 ing upward, two-thirds of a line long, and about one-third of a line 

 broad ; axis fuscous.
