Observations. — The specimens attributed to Tenison Woods' 

 species by Professor Tate as occurring in the "lower and upper 

 beds at Muddy Creek, but common in the latter only," do not in 

 my opinion belong to the same species as the Table Cape speci- 

 mens, and on that account the Victorian fossil, which is a very 

 characteristic miocene form, stands in need of a name. In order 

 to clear up the confusion surrounding this species I intend, in my 

 next paper, to redescribe and rename the Victorian miocene fossil, 

 with full particulars as to the points wherein it ditiers from the 

 Table Cape .species. 



123. Cytherea tenuis, Tate. 



C. tenuis, Tate, Lam. II., 1887, p. 159, pi. xiv., fig. 16. 



C. ebnrjiea % Johnston (non Tate), Ceo. Tas., p. 233, pi. xxxii., 

 figs. 9, 9a. 



Observations. — The shell recorded and figured by Mr. R. M. 

 Johnston as Cytherea eburnea, Tate, does not appear to be 

 Professor Tate's species, but may probably represent C. tenuis, 

 Tate. 



124. Dosinia densilineata, sp. nov. PL IV., figs. 5, 6 and 7. 



Shell orbicular, thin to thick, varying from about "5 mm. or less 

 in young shells to 3 mm. in thickness in the adult form ; fairly 

 convex, most marked in the umbonal region, maximum con- 

 vexity situated about one-third the length of the umbo-ventral 

 diameter from the dorsal margin in about the middle line of the 

 shell. Umbones well defined, regularly convexly incurved 

 obliquely towards the anterior end, from which they are situated 

 about one-third the length of the shell. 



Lunule elongate cordate, deeply depressed, finely and closely 

 lamellose. The shell immediately anterior to the umbo and in
