Mr Etheridge on Fossils from Bowen Riccr Coed field. 305 



Loc. and Horizon. — Head of Pelican Creek, near Mount 

 Diolin (Marine Series, Nos. 1 and 2). 



Goniatites, sp. ind. 



A second species is present differing from G. micronij^halus 

 in having a very much sharper back. It appears to be nearer 

 to G. striatus (Dana)* than to Morris's species. 



Loc. and Horizon. — Eosella Creek, two miles above Havi- 

 lah Paddock. This is an important fossil, as it is another of 

 those occurring in a marine band in the Fresh- Water Series 

 (No. 187). 



Collector. — E. L. Jack, Esq., etc. 



CEETACEOUS SPECIES. 



Cephalo]JodcL 

 Genus Crioceras — HEveilU, 1837. 



(Mem. Soc. Geol. de France, ii., p. 313.) 



Crioceras Jackii, sp. nov. — PL XVIL, figs. 55-58. 



Sp. Char. — Shell non-involute, with the whorls close but not 

 touching; round or slightly flattened at the sides; tubercles 

 blunt and node-like, arranged in six rows, two on each side 

 or flank of the whorl, and two on the back or dorsal ed^e ; 

 those on the sides become less apparent and entirely disappear 

 ultimately as the end of the last volution is approached, but 

 those on the dorsal edge remain. The costae are of two sizes, 

 the non-tuberculate ribs being all of one size, whilst those 

 bearing the tubercles are larger and separated one from the 

 other sometimes by two, sometimes three, of the former ; they 

 are all entire and scarcely at all curved. 



Ohs. — Doubts existed on the first examination of the two spe- 

 cimens before me as to their identity with the genus Crioceras 

 owing to the contiguity and close approximation of the whorls ; 

 the length and size, however, of the dorsal tubercles on the 

 inner volutions clearly demonstrated that the whorls were 

 separate from one another.
