shell referred to above, rather than to Leda vagans, Tate, as 

 Professor Tate believed.* 



The data afforded by the figure of the cast and the restoration 

 of N. marthce are insufficient for the purpose of identification ; 

 but even if we considered the claim of the figured shell to be 

 valid as representing the true outline, the drawing shows too 

 coarse a concentric lineation for a close comparison to be made 

 with L. opiculata, and therefore we should not be justified in 

 displacing Tate's species for that given by M'Coy. 



Tellina krausei, M'Coy. 



This fossil is clearly identifiable with Tate's Semele krauseana, 

 both in contour and in the visible traces of the growth-lines. When 

 Tate described his specimens of Semele krauseana he was aware 

 of their probable identity with M'Coy's species, for he remarks f 

 in his description of this shell (p. 170) : — 



"Professor M'Coy, in Report Geol. Surv., Victoria, No. 2, 

 figures on p. 22, under the name of Tellina krausei, the impression 

 of a Tellina-like shell obtained near Stawell, and states that the 

 species is common in the Tertiary beds at Schnapper Point. It 

 may possibly be Semele krauseana, with which it agrees in shape, 

 but doubtfully so, as the drawing indicates an ornamentation of 

 thick concentric ridges, unless, however, it be faulty in this 

 particular. The figure is unaccompanied by description." 



Since both species were dedicated to the same man, it will 

 require little change to eft'ect the needed correction. 



With regard to the figure given in the " Progress Report," 

 Tate was correct in his surmise that the concentric ridges were 

 the result of faulty drawing ; and, further, it may be stated that 

 the figure on p. 22 is about two-thirds the natural size, although 

 this is not indicated. 



DiTRUPA WORMBETIENSIS, M'Coy. 



This fossil is somewhat common in the ironstone from Stawell, 

 and there can be no doubt whatever as to the identity of this 

 little annelide, which I have compared with the original examples 

 from Wormbete Creek, in the Barwon valley, in the National 

 Museum collection. 



The species enumerated by M'Coy from Stawell may therefore 

 stand as follows : — 



(i.) Lepralia stawellensis, M'Coy = Lepralia sp. cf quadrata, 

 Macgill., sp. 



(2.) Ntictda marthce, M'Coy = Leda (?) apicidata, Tate. 



(3.) Tellina krausei, M'Coy, should read Semele krausei, M'Coy 

 sp. (synonym S. krauseana, Tate). 



(4.) Ditrupa wormbetiensis, M'Coy.

 hicida, T. Woods sp., under which Tate's remarks are made, was subsequently 

 changed to L. vagans, the earlier name having been preoccupied. )
