OF NEW SOUTH WALKS. 311 



depressed about half the height ; septa thin, narrow, with rather 

 large granulations in six cycles, and the first four being equal, 

 give them the appearance of being in 48 systems of three cycles. 

 Rather numerous on the N. E. coast, within the tropics, and 

 in the Gulf of Carpentaria, at depths varying from 10 to 30 

 fathoms. Moreton Bay (?) 



Flabellum candeanum, M. Edw. ty H. 



Corallum moderately compressed, the lateral costae forming an 

 angle of about 45°, each furnished with three strong spines 

 directed outward and downward, one near the base, the other 

 near the centre, and the third at the edge of the calice ; the 

 ends of greater axis in a pointed arch, and very little below the 

 plane of the short axis ; columella fossa deep ; septa in five 

 cycles, but the fifth not seen in one half of the middle systems ; 

 first and second orders equal. 



In the Chinese Seas, and found fossil in Australia, in the 

 Muddy Creek, Greelong and Murray beds. 



Flabellum distinctum, M. Edw. & H. 



Corallum subpedicellate, but becoming free in the adult state, 

 having scarcely any scar as the pedicel is finely pointed, where 

 it is much compressed, lateral costse forming rather more than a 

 right angle ; calice somewhat compressed, and the edges rising 

 from the ends of the greater axis so as to make almost a half 

 circle ; septa in six cycles, the three first equal, giving the 

 appearance of 24 systems composed of seven septa each. Alt. 

 25, major axis 33, minor 18 mil. 



Japan and a Miocene fossil in Australia (Muddy Creek and 

 Geelong.) It has been dredged at 70 fathoms on the E. coast, 

 Cape Three Points. Dr. Rayner. 



Flabellum rub rum, Quoy tip Gaimard. 



Corallum always attached, much compressed ; costse hardly 

 distinct under the folds of the epitheca ; calice deep, the summits 

 of the lesser axis a little above the major axis, and slightly 

 re-entering ; columella (?) formed by somewhat thick and
