calices are visible. In tlie peculiar mode of branching it 

 resembles C. contortilis (mihi). I only name the specimen pro- 

 visionally. App. Off. Cat., p. 41, No. 90. White Eock Point, 

 north of Mokihinui River, West Coast, Nelson ; IV. or V. 

 The specimen is described as a Lower Tertiary form of net- 

 coral; so there must be a mistake in the label, and probably in 

 the locality. 



Group — AsTRANGiACE^. Ncw genus — Scolangia. 



Astrangiacese united by a calcareous stolon, which covers the 

 calices with concentric layers. Corallites inclined. No spiniform 

 processes on the septa, and no columella. 



Scolangia parvisepta, n. s. Corallum much inclined, nearly 

 cylindrical, thick and solid. Walls in very thick concentric 

 layers. Calice open and deep ; slightly narrower at the base. 

 Septa in six systems of four cycles, which differ very little in 

 size ; not exsert, and projecting only a short distance from the 

 wall, leaving a wide and deep fossa, very undulating at the base, 

 where the higher orders are more prominent. Height, about 15 

 millim.; width of calice, 12 millim., but no complete calice in 

 the specimen. 



There are no members of the group Astrangiacese known in 

 the Australian tertiaries ; but the genus Cylicia is widely spread 

 both in Australia and New Zealand, and has probably many 

 species. The entire septa, their equality and inconspicuous 

 character, are all peculiar features in this fossil, as the family 

 is remarkable for the prominence of the higher orders of 

 septa. Aj)p. Off. Cat., p. 36, No. 24-. Conway River, Nelson, 

 from Leda marls ; VI. Fig. 18, portion of calice, natural size. 



Section — Madreporaria perforata. Family — Madreporide. 

 Sub-family — Eupsamminte. Genus — Balanophyllia. 

 Searles-Wood, 1844. 



Simple pedicellate corals, very porous, ^ath a well-developed 

 fourth cycle and columella. In all the known species the septa 

 unite according to the various orders, forming an intricate net- 

 work right up to the columella. 



This genus was not a large one until very lately. It was 

 known only by a few European Tertiary fossils, and two or three 

 living species from temperate seas, with one tropical exception. 

 I am not aware to what extent this has been altered by the " Chal- 

 lenger'^ dredgings, but the discoveries in the Australian tertiaries
