Well developed examples of this form occur in the Filter 



Quarries. The species has already been recorded from the 



Balcombian of Port Phillip and Muddy Creek. 



Verneuilina ens:/ form is, sp. nov. (Plate II., Figs. 1«, b). 



Test triangular, elongate, very slightly tapering : septa 

 nearly flush with the surface, or slightly depressed. Surface of 

 test slightly rough, granulate near the aboral end, but not 

 spinous, as in V. spinidnsa, Reuss., to which this form bears 

 some resemblance. 



Length. .517 mm. : greatest breadth, .224 mm. 



Remarks. — This species is prol»ably that referred to by Mr. 

 Howchin^ as Verneuilina sp., and he reniarks (loc. cit.) that it re- 

 sembles F. siDinulosa, but for the elongate contour, the plane 

 surfaces and absence of spines. Filter Quarries.

This interesting little hyaline species has quite recently 

 been described by the above-named authors, who give some 

 excellent figures of the shell, and good diagrammatic drawings 

 showing the internal structure. The species was previously de- 

 scribed from the Paris tertiaries under Giimbel's name of 

 Clavulina eocaena ; and Heron-Allen and Earland have shown 

 that it is distinct from that species and identical with their 

 Selsey specimens. One of the chief points of interest is their 

 discovery of the same species in washings from the polyzoal 

 rock of the Filter Quarries, near Batesfoid. So far as I have 

 found, the species is not common. I am indebted to Mr. Earland
