Polyzoa .. .. .. About 43 species and varieties were 
noted from the Janjukian, some of 
them excessively common, especially 
in the white polyzoal limestone. 
Amongst these common forms may 
be mentioned :— 
Cellaria acutimarginata, MacGill. 
,, acutiloba , Busk sp. 
,, australis, MacGill. 
,, contigua, MacGill. 
,, rigida, MacGill., and vars. 
perampla, Waters, and 
venusta, MacGill. 
Lunulites canaliculata, MacGill. 
Selenaria cupola , T. Woods. 
,, marginata, T. Woods, 
and vars. lucens, 
MacGill., pulchella, 
MacGill., and spiralis, 
Chapm. 
Macropora clarlcei, T. Woods sp. 
Tessaradoma elevata, Waters sp. 
,, magnirostris, MacGill. 
Lepralia elongata, MacGill. 
Bipora philippinensis, Busk sp. 
Smittia tatei, T. Woods sp. 
Porina gracilis, M. Edw. sp. 1 
Cellepora fossa, Haswell sp. 
„ gambierensis, T. Woods 
,, tridenticulata, var. num¬ 
mular ia, Busk. 
Retepora spp., indet. 
Terebratulina flindersi, Chapm. This has also occurred at Flinders, and 
is a restricted Janjukian fossil. 
Terebratella acutirostra, 
Chapm. 
T. portlandica, Chapm. 
A Janjukian form related to T. woodsi , 
Tate, which has a more extended 
range, namely, into the Kalimnan. 
This Janjukian brachiopod also ranges 
into the next stage, and belongs, 
like the former species, to the T. 
woodsi group. 
Magasella lunata, Tate .. Confined to the Janjukian of the bores. 
It is interesting on account of its 
previous occurrence in some bores 
in South Australia, viz., the Croydon 
bore, 400-1,230 feet, and the Mur- 
gurdawa bore at 213 feet. 
1 The lobed, bilaminate form is here the most usual. On the other hand, MacGillivray says, in 
Tert. Polyzoa Viet., 1895, p. 103 :—“ The lobate form is that usually found recent, while the great 
majority of the fossil specimens are cylindrical.”
