Obsefvations. — This is a comparatively Ijroad form of Conu- 

 laria, well-known from Upper Oi'doviciau to Silurian strata in 

 Europe and elsewhere. Tt has also been recorded with reser- 

 vation by de Koninck froin Rock Flat Creek, New South Wales 

 (Silurian). 



Occur-reiice and Horizon. — In the hard grey mudstone at the 

 junction of the Woori Yallock and the Yarra : coll. Geol. Surv. 

 Vict., B 23 [1125]. Also in the ochreous mudstone of Wilson's, 

 N. of Lilydale. [2362-3J : presented by Mr. J. T. Jutson. 

 Silurian (Yeringian, and perhaps younger). 



Conularia ornatissima, sp. nov. (PI. XXXI. Figs. 13, 14). 



Specific Cliaracters. — Shell broadly conical, with blunt and 

 rounded apex ; angle of divergence about 50\ Transverse 

 striations fine, and strongly arched ; at 10 mm. from the 

 apex, 0.2 mm. apart. The intercostal striae fine, and 

 traversing the transverse ridges. Length of figured specimen 

 18 mm.; but indications on matrix of one example point to its 

 having bad a much greater length. 



Ohsefvatiois. — This Conularia belongs to the type of C. nobilis, 

 Barrande^ fi-om the Upper Ordovician of Bohemia (Stage ])). 

 In our species, however, the vertical ornament is not so j)io- 

 nounced, and therefore it does not appear as thougli the 

 shell were continuously striated from apex to mouth. The 

 interspaces between the vertical costuhie are wider than in ('. 

 nobilis. 



Occurrence a7id Horizon. — In the blue and yellow mudstones 

 at South Yarra (Yarra Improvements). [118G, 2361]. Collected 

 by iNlr. F. Spry. Siluria!! (Melbournian).
