MADREPORARIA FROM THE AUSTRALIAN AND 

 NEW ZEALAND COASTS. 



By John Dennant, F.G.S. 



[Read October 2, 1906.] 



Plates V. and VI. 



The following corals have been submitted to me for de- 

 scription : — From South Australia, by Dr. Jos. Verco and the 

 late Professor Tate; from New South Wales, by Messrs. Hed- 

 ley and Petterd ; and from New Zealand by Mr. Henry Suter. 

 They are arranged in 15 species and as many genera. Nine 

 species prove to be new, three were described by Moseley from 

 the "Challenger" dredgings, two are corals described by Ten. 

 Woods from the coast of New South Wales, and one is a 

 varietal form of a tertiary fossil. 



TURBINOLID^. 



Genus Flabellum, Lesson. 



Flabellum australe, Moseley, Report on Corals, 1881, 



pp. 173-4, pi. vii., figs. 4, 5. 



This coral was dredged at 120 fathoms off Twofold Bay 



by the "Challenger" Expedition, when eleven specimens were 



obtained. Lately it has been dredged in very large numbers 



20 miles north-east of Port Jackson, by Messrs. Hedley and 



Petterd, at a depth of 250 fathoms. It has also been dredged 



by Dr. Verco at 90, 120, and 130 fathoms off Cape Jaffa, and 



at 110, 150, and 200 fathoms off Beachport. 



The specimens are generally of large size, but none reach 

 the dimensions of Moseley's largest example, viz., 57 mm. 

 high and 65 mm. broad. The largest sent to me is 38 mm. 

 hio^h and 44 mm. broad. 



Genus Sphenotrochus, Milne-Edwards and Haime. 

 Sphenotrochus emarciatus, Duncan : var. perexigua, 7iov. 

 A fossil coral from the Australian tertiaries was describ- 

 ed by Duncan in 1865 under the name of Sjjhenotrochus emar- 

 ciatus.^ Two years later this author re-described the same 

 coral, and in exactly the same words, but with a new specific 

 name, viz., S. excisus.] Af* he gave no reason for the change, 

 and I know of none, the older name is here restored. The
