794 C. FORSTER-COOPER. 



The spines are irregularly placed, and bluntly conical with here and there a tendency 

 to be knobbed at the end. A few exceedingly small triangular secondary spines are scattered 

 irregularly among the larger ones. 



This form is not unlike C. anguina in general appearance. The polyps are a good deal 

 larger and the spines of slightly different shape ; the colour is also different, a point however 

 of very doubtful specific value. The presence of secondary spines, which are not found in 

 C. anguina, is sufficient to distinguish the two forms. 



Locality. Suvadiva atoll, 40 y". 



Genus Stichopathes Brook. 

 An elongate unbranched stem with the polyps arranged on one side of the stem only. 



4. Stichopathes maldivensis n. sp. PL LXV. fig. 4.. 



A single straight corallum 85 cm. long, tapering from 4 mm. at the base. Corallum jet 

 black. The polyps were unfortunately in very bad condition. Enough could be made out, 

 however, to shew that they were arranged on one side of the stem only, white in colour 

 and with six long digitiform arms. 



The spines were of two kinds, the primary ones stout, bluntly conical with rough sides 

 and knobbed at the end. They are an-anged in irregular spirals. The secondary spines are 

 exceedingly small triangles scattered quite irregularly.

Order Ramosae Brook. 

 Colony free and branched. 



(icnus Antipathes (Pall, em Schultze — Antipathella Brook). 



.5. Antipathes spinosa (Carter). PI. LXV. fig. 5. 



A small colony 7 cm. high, main stem erect giving oft' secondary branches at intervals 

 of 2 — 3 mm. apart, which again bear very slender alternate pinnules. 



The polyps are exceedingly small, arranged on one side of the pinnule only, white in coloui\ 



The spines are rather long, sharp and hooked upwards, with a distinct spiral arrangement, 

 which is somewhat obscured in places.

The colony is erect and consists of a very thin black main stem, which almost imme- 

 diately gives off other branches at different angles. These latter frequently are further 

 branched. The colonies are small, the largest measuring only 8 cm. in total height. 



The polyps are white, of variable size but all exceedingly minute, the average size being 

 not more than "75 mm. They are arranged on one side of the stem only. They are rather 

 regularly placed at intervals of 1 mm. fi-om one another. The tentacles are for the size of 

 the polyp rather long.
