Victoria a Fossils. Part XVII. 357 



.Vaufl/us felir,' sp. uov. (Phite VL, Fig. U; Plate VII., Fig. 15). 



Description. — Shell somewhat compressed, or only moderately 

 inflated, with a well rounded periphery; whorls increasing rapidly. 

 Camerae high, and with the sutures slightly undulate; few in num- 

 ber, nine in the last whorl. A feeble annular lobe on the im- 

 pressed zone. Umbilicus rather wide and deep. Aperture roundly 

 dome-shaped; higher than wide. 



Dimensions. — Maximum diameter of shell in type specimen, 85 

 mm. ; minimum diameter, 63 mm. ; height of aperture, 47 mm. ; 

 width, 42 mm. ; width of umbilicus, 7.5 mm. 



Observations. — This form differs in many respects from any other 

 known Victorian species. Its salient characters are — its com- 

 pressed form compared with N . halcombensis and N . geelongensis, 

 the wide umbilicus, and the small number of camerae in each 

 whorl. 



Occurrence and Horizon. — Happy Valley, South Australia 

 (Magellania j)ectoralis beds)2 Janjukian (Miocene). Type speci- 

 men in the Dennant coll. 



DIBRANCHIATA. 



Fam. Sepiophoridae. 

 Genus Notosepla, gen. nov. 



Notosepia cliftonensis, sp. nov. (Plate VII., Figs. 16, 17; Plate VIII., 

 Figs. 20-22). 

 Description. — Shell or sepion large and comparatively thick, 

 but variable in the latter respect, according to habitat; triangu- 

 lary ovate in ventral aspect. Alveolus moderately deep, filling up 

 with age. Ventral lip of alveolar border recurved, and sometimes 

 quite pendent; inner surface of lip radiately grooved or fluted. 

 Back and sides of sepion coarsely reticulated or labyrinthic, and 

 spongy. Vestigial septation of the internal surface of the pro- 

 ostracum faintly marked, but stronger than in the living Sepia. 

 Pro-ostracum strongly convex dorsally, at the anterior end be- 

 coming depressed and marked with strongly-arched lamellar 

 growth-lines. Mucro thick, cylindrical, and bluntly terminated; 

 in fully grown specimens directly in line with the back of the pro- 

 ostracum, but in younger specimens having a slight tendency to 

 recurve.
