 [Read 9th June, 1910.] 



Some seven years ago Dr. Verco of Adelaide, S.A., sent to 

 the late Mr. J. Dennant some Corals and Polyzoa which he had 

 dredged in South Australian waters. The Polyzoa Avere sub- 

 mitted to me for examination, and among them I found four 

 new species, three of which belonged to Selenaria, and as I 

 was then dealing with some fossil Selenariidae, and as these 

 recent forms enabled me to correct some errors that had arisen 

 with regard to the names of the species, I included a description 

 of them in a paper treating of the Australian Selenariidae 

 generally ; ■**■ but being busily engaged with the fossils I did not 

 then describe a very interesting massive form which was new. 

 Having at the time returned the specimens to Dr. Verco, I 

 lately asked him to kindly send me a typical specimen for 

 description and presentation to our Museum, and' he most gene- 

 rously sent me a fine series of specimens, and stated that I was 

 quite welcome to present them to our National Museum, which 

 I have done. 



Tills new species is 



Cellepona verticalis, n. sp. (Pis. VII.-IX.). 



The zoaria are tiabellate and proliferous, being composed of 

 vertical laminae, of which there are at first generally three 

 (sometimes four), in an upright position connected at their 

 inner edges, or rather extending from a vertical central line 

 laterally. Afterwards other laminae are formed, generally at 

 obtuse angles, one after another, until the zoaria are extremely
