I agree with Pritchard and Gatliff, P.R.S., Victoria, 

 p. 189, 1899, iu uniting these species together with 

 Scalariformis. The large specimen mentioned seems^to 

 be a form of vincta. 



(Fig. 1.) 



Mitra scaliformis. 



Mitra tasmanica. (Fig. 1 .) 



On the card are 4 specimens, 

 amongst which it is easy to 

 identify the type and vars. A and 

 B. I consider this to be a very 

 distinct species, not to be con- 

 founded with any one of our 

 ribbed mitras : its peculiar form and distinct spiral lirae are 

 very constant. Woods gives no habitat, but the few speimens 

 I have received are from the Derwent Estuary. Var. A. 

 This is M. tatei angas, and in no sense a var. of this species. 

 Var. B is very distinct, and whilst 

 I do not consider it to be a variety 

 of this, it has some resemblance 

 in form. It almost merits a specific 

 name ; but these shells are so 

 variable and so overloaded with 

 synonomy already, that, without '^' 



a large series of specimens, it would be unsafe to separate it 

 as a new species. It may be an extreme form of M. vincta or 

 M. scalariformis. I have 2 specimens from Port Esperance, 

 exactly similar. Fig. 2. 



Mitra teresiae. 



Mitra weldi. 



Mitra scita. 



Marginella allporti. 



Marginella cyprseoides. (Fig. 3.) 



Marginella miuutissima. 



Marginella Stanislas. I now believe 



this to be a syn. of M. volutella. 



(Fig. 3.) 



Marginella tasmanica. (Fig. 4,) 



Colurabella badia. 



Columbella roblini. 



Columbella dictua. I consider now 



that these 8 species should be 



combined as varieties of one 



very variable form. C. vincta, 



Tata, should also be included ; 



in fact, one of the specimens 



mounted as C. hadia is the vaiety vincta. Reeves's 



figure C. irrorata is, in my opinion, another variety.
