22 MR. FREDERICK CHAPMAN ON THE 



Muddy Creek Lower Beds, since it was from that deposit that this shallow- 

 water tropical species was first recorded as a fossil. 



Our figured specimen is most like that depicted by Millett from the Malay 

 Archipelago. 



Occurrence. — Grrice's Creek, very rare ; Altona Bay Coal-Shaft, very rare. 



G-enus Articulina, cV Orhigny.

 Journ. R. Micr. Soc. p. 613. 



As in the majority of the recent forms hitherto found, our specimen has 

 lost its initial milioline series of chambers. 



This is probably the first occurrence of the species as a fossil. It is found 

 living ofE Kerguelen Island, the coast of New Guinea and the Malay 

 Archipelago. 



Occurrence. — Grice's Creek, very rare.

CoRNUSPiRA CRASSISEPTA, Brady. (Plate 2. fig. 45.) 



Cornuspira crassisepta, Brady, 1882, Proc. Roy. Soc. Edin. vol. xi. p. 714 ; id., 1884, 

 Rep. Chall. vol. ix. p. 202, pi. 113. fig. 20; Howchin, 1889, Trans. R. Soc. S. Australia, 

 vol. xii. p. 4. 



The geographical distribution of this species is peculiar. It is the most 

 abundant of the Cornuspirce in the Tertiaries of South-eastern Australia, and 

 in the living condition has only been recorded from one locality, namely 

 the Faroe Channel, "warm area," 530 fathoms. Flint* figures two examples 

 of a similar shell in the same group with C. involvens. They may possibly 

 belong to this species, but their peripheral aspect is not shown. Flint's 

 specimens came from soundings in the Caribbean Sea, Straits of Yucatan and 

 coast of Georgia, from 276 to 463 fathoms. 



C. crassisepta was found by Howchin in the Lower Bed at Muddy Creek. 



Occurrence. — Grice's Creek, very common; Balcombe's Bay, very common: 

 Kackeraboite Creek, common; Altona Bay Coal-Shaft, very common.
