Cinachyra coactifera (Lendenfeld). 



Tethya coactifera, Lendenfeld, 1906, p. 75, pi. ix, figs. 1-16, pi. x, figs, i-io; Cinachyra 

 coactifera, Burton, 1929, p. 396. 



Occurrence. St. 39: South Georgia, 179-235 m. 



Remarks. The eleven specimens range from 6 to 12 cm. in diameter. The majority 

 are without conspicuous surface pile or basal tuft, but in two of them both these 

 features are well developed. The porocalices in the dried sponge are inconspicuous and 

 might be easily mistaken for small and simple oscules, and it is probably on this account 

 that the species was first referred to Tethya (= Tetilla). 



Distribution. Kerguelen.
