72 CEITICAL REMARKS ON TABLE CAPE FOSSIL MOLLUSCA, 



Phurotoma pullulascens, Tenison- Woods. 



From a specimen in my collection, compared with 

 Johnston's co-type. (Plate X., fig. 12). 



Pleurotoma sandleroides, Tenison- Woods. 



Fro'm a specimen in my collection, compared with the 

 type, and co-types. (Plate X., fig. 13). 



Daplinella cohunhelloides, Tenison- Woods. 



From a specimen in my colleiction, compared with 

 Johnston's co-typeis, and also with the type, and coi-types of 

 Tliala marginata, Tenison-Woods, which I consider synon- 

 ymous. None of these specimens are perfect, most of them, 

 much the reverse; usually the columella plates are ahsent 

 b)'- erosion, or only slightly in evidence. The axial ribbing- 

 varies much in different individuals ; it may be present 

 only on the first two adult whorls, or may extend onto^ the 

 body- whorl. (Plate X., fig. 14). 



Daphnella graciUlirata, Tenison-WoodsL 



From one of Johnston's co-tyf)es, and compared with 

 the broken type. (Platei X., fig. 15). 



Columhella cainozoica, Tenison-Woods. 



From the type, which is a small broken specimen, and 

 probably in a juvenile state. (Plate XL, fig. 16). 



Columhella oxleyi, Tenison-Woods. 



From the type. Although I have not the material 

 to e'ntirely bridge the gap, I feel satisfied that this is the 

 adult stage of the last species. (Plate XL, fig. 17). . 



Rissoa duhia, Johnston. 



No specimen of this was present. Asi the name is 

 preoccupied amd there is no authentic specimen, and the 

 author'si figure in "Geology of Tasmania" shews a shell 

 that could hardly belong to the Rissoidice, the species had 

 better be abandoned. 



Rissoina iateana, Tenison-Woods. 



I have figured a specimen in the Johnston collection, 

 which is probably the type, as the figure in Geo. Tas. is 

 very poor. This belongs to the genus HauraHa near H. 

 descrepans, Tate and May (Rissoa). (Plate XL, fig. 18).
