 loose, spreading branches. App. Off. Cat., p. 40, No. 76. Te

Family — Stylasterid.e. Genus — Sporadopora. Mosely, 



1878. 



Pores of both kinds simple. Gasterozooids with four tentacles. 



Sporadopora marginata, n. s. I give this name to two 

 pieces of a hydroid coral from the Chatham Islands. They are 

 both much worn, but there is quite sufficient to show that they 

 belong to Mr. Mosely's genus, as above. The species is new, as 

 the pores have a raised margin, and the style is different, and 

 quite visible at the mouth of the gasteropores. There is no 

 regularity in the arrangement, but the pores are close, and the 

 reticular tissue between is as if it were punctured. One of the 

 branches is almost hollow, but irregularly so, as if perforated 

 by an annelid tube. 



This genus was unknown until described by Mr. Mosely 

 (Proceed. Hoy. Soc, Vol, 173, p. 94) from a single species, 

 obtained on one occasion only by the " Challenger," off the mouth 

 of the Rio de la Plata, at 600 fathoms. The fossil therefore 

 possesses unusual interest, and no doubt more will be found.
