14 NEW ZEALAND PALEONTOLOGY. 



Flabellum, sp. A fragment of what is clearly a species of 

 Flabellum is contained^ with other fragments of fossils^ in speci- 

 men No. Q7 , from Oamaru. It may be the same as No. 42, 

 which now follows. 



Flabellum laticostatum, n. s. Corallum large, finely pedi- 

 cellate, almost circular in lateral outline, compressed acutely, 

 but expanding into a rather broad calice, the whole form of 

 which is beautifully curved and regular. Epitheca thin ; not 

 corrugated. Costa broad and flat, regularly bifurcating, and 

 all equal. The calice is destroyed by matrix, so that the septa 

 are not seen, but apparently forming only five cycles, as far as 

 the costa can indicate. The fewness of the cycles and the costa 

 distinguish this species from F. circulare ; but better specimens 

 are wanting to determine other details. It is, however, much 

 of the character of all the New Zealand species, and like a good 

 many described forms. Alt. 52, major axis 80, minor 21 

 millim. App. OfP. Cat., p. 38, No. 42. Broken River, Can- 

 terbury; V. Between Mount Brown and Weka Pass limestones. 

 Fig. 11, coral, natural size. 



Flabellum sphenodeum, n. s. Corallum tall, compressed, 

 cuneate, often with two aliform processes at the base, below 

 which there is in some specimens a semicircular basilar attach- 

 ment much compressed. Epitheca a fine pellicular covering, 

 easily worn off. Costa slender, prominent, corresponding with 

 the septa. Calice deep, open, oval. Septa in six systems of 

 four cycles, but difficult to distinguish, as the first three orders 

 are nearly equal ; edges much thickened and uniting below. 

 Alt. 20 circiter, major axis 15, minor 8 millim. Fig. 12, a, b, c, 

 three corals, natural size. 



This coral is a good deal like the Australian Tertiary Placo- 

 trochus elongatus, and inasmuch as it approaches the Australian 

 type it differs from all the other species of Flabellum in the 

 New Zealand beds. App. Off. Cat., p. 38. No. 44 : Thomas 

 Biver, Canterbury ; V. No. 46 : Mount Caverhill, Nelson ; V. 



Flabellum radians, n. s. This fossil is the external cast of 

 what is probably a Flabellum; and closely allied to F. circuJare. 

 As none of the septa are seen, I give it a name provisionally. 

 The costa bifurcate, and are beautifully radiate. The coral is 

 narrowly pedicellate, and the ends of the major axis of the 

 calice are neai"ly horizontal. App. Off. Cat., p. 38, No. 48.
