13 NEW ZEALAND PALEONTOLOGY. 



lia and one in New Zealand. Recent deep-sea dredgings have 

 also revealed many species in cold and deep seas ; and the fossils 

 of the Australian Tertiary formations manifest that some species, 

 which are now tropical, were formerly found in deep seas, in 

 latitudes as far south as 40°. Five or six species are found in the 

 Australian tertiaries, some of which, such as Flabellwn victories 

 and F. [jambierense, are peculiar and exceptional forms. From 

 the fossils here enumerated it will he seen that the New Zealand 

 seas, in Tertiary times, were rich in sj)ecies of this genus, hut not 

 of an exceptional type. Some of those I here enumerate as 

 distinct may prove to he varieties of one species. As a rule the 

 evidence is unsatisfactory, as most of those described were found 

 as casts only. It may he stated generally that the species are 

 inhabitants of deep seas. 



Flabellum circulare, n. s. Corallum spreading from a 

 narrow pedicel into almost a comi^lete circle. Calice compressed, 

 narrowly oval, or flat on one side and curved on the other. 

 Epitheca fine, and only slightly corrugate with lines of growth. 

 Septa close and long, apparently in six systems, with six cycles. 

 Though this appears to be one of the very commonest of the New 

 Zealand Tertiary corals, I have not as yet seen a specimen in 

 which a view of the calice could be obtained. In only one case 

 have I seen the fossa, and that was at the base of a cast. The 

 coral structure is always removed, and, though what remains 

 often looks like septa, in reality it is only casts of the loculi 

 between. The fossil is a very remarkable form, and we have 

 nothing at all like it in the Australian tertiaries. There is a 

 siiecimen in the collection which is a stone all covered with im- 

 pressions of one side of this Flabellum, showing how gregarious 

 it must have been in its mode of growth. App. Off. Cat. 

 No. 34: Shakespeare Cliff, Wanganui; III. No. 86: Weka 

 Pass, Canterbiiry ; VI. No. 91 : North bank of Maruwhenua 

 River, Waitaki, Otago, from the Phorus beds overlying the 

 Ototara limestone ; VI. Fig. 7, coral, natural size. Also

Flabellum rugulosum, n. s. Corallum tall, pedicellate, 

 broadly cuneiform, and tapering to a very narrow pedicel. Out- 

 line rugged and irregular. Epitheca thin, not concealing the 

 costa or the lines of growth, which are deeply marked. Calice 

 broad, rounded at the ends of the major axis, which are depressed. 

 Systems six ; cycles five. Septa granular, first three orders equal.
