258 RECORDS OF THE AUSTRALIAN MTT8EUM. 



Loc. — The following localities considerably extend our knowledge 

 of the distribution of this coral : — Fernbrook (Limekilns) near 

 Bathurst (5. ^^AeHc^gre— Aust. Mus.); Isis River, Parish Lincoln, 

 Co. Brisbane (C. Cullen — Geol. and Mining Mus , Sydney) ; Cavan 

 Holding, Parish Cavan, Murrumbidgee River, Co. Cowley (C. 

 Cullen — -ibid.); Quarter of a mile south of Alum Creek, Parish 

 Warroo, Murrumbidgee River, Co. Murray (C. Cullen — ibid.) 



Genus Syringopora, Goldfuss, 1826. 

 (Petrefacta Germanise, 1826, i., p. 75.) 



Syringopora sPELiEANus," sp. nov. 



(Plates xxxvii., fig. 2; xxxviii.) 



Sp. Char. — -Oorallum large, composed of loosely aggregated 

 clusters of corallites. The latter are long, at least five inches, 

 often contiguous, parallel to or diverging from one another, united 

 by endothecal outgrowths, or by lateral union of their walls ; 

 diameter five and a half to six and three quarter millimetres. 

 Endothecal outgrowths strong and short, with a diameter of one 

 millimetre. Septa small and numerous (at least sixty in a cycle), 

 short, dentate, terminating in fine filaments. Visceral chambers 

 oval or round. Tabulse very numerous, infundibuliform, the 

 invagination long and deep, very unsymmetrical in section. 

 Lateral budding plentiful. 



Obs. — A remarkable and peculiar Syringopora, in all probability 

 forming large colonies, the largest specimen seen being a mass 

 seven inches by five and a half. The corallites are either close to 

 one another, or separated by considerable intervals, and are either 

 parallel to or diverge from one another at various angles. They 

 are long (five inches at least), occasionally united by endothecal 

 outgrowths, but more commonly by lateral union of their walls. 

 The diameter is considerable even for a Syringopora, from five 

 and a half to six and three quarter millimetres, hence the colonies 

 possessed a strong and robust appearance. Similarly the endothecal 

 outgrowths when present were strong and robust, although short. 



Both the septa and tabulae are numerous, the former peculiar 

 in that, for the diameter of the corallites, their size is remark- 

 ably small. The wall of each corallite being rather thickened, the 

 septa present the appearance of very numerous short teeth, each 

 terminating in a short fine filament. Disintegration, apparently 

 before fossilisation, had often removed these acicular terminations, 

 giving to the corallite inner edges a ragged appearance, and 

 reducing the septa to a series of tooth-like projections. The pre- 

 cise number of septa in a cycle is uncertain, but there are certainly
