APPENDIX TO ALCYONAMA. 183 



The diagnosis reads : " A somewhat sponge-like cavernnlarid, with a flattened 

 ovoid stock separated by a constriction from a comparatively slender sterile trunk; 

 with dimorphic retractile polyps, the antozooids not exceeding 1 niilliin. in length, the 

 much smaller siphonozooids scattered irregularly among the autozooids ; with 

 abundant densely spiculate ccenenchyma, traversed by three longitudinal central 

 canals passing down into the trunk ; with smooth hyaline spicules bearing peculiar 

 digit iform terminal processes and showing very characteristic annulations, especially 

 near the ends." 



Locality : Cheval Paar, Gulf of Manaar, 6 fathoms. 



Note. Further inquiry into the history of the specimen listed by Professor 

 Herdman and Mr. Hornell in their diaries as a possible Corallium sp. has shown 

 that this tentative identification was mistaken. We therefore withdraw the para- 

 graph referring to this specimen on p. 289 of Part III. of this Report. J. A. T.
