Peron, who discovered this species at Maria Island, Tasmania, 

 described it as " une coquille interieure, qui me semble devoir 

 constituer un genre nouveau, voisin des Trochus, et dont une 

 espece assez semblable se retrouve fossile a Grignon pres Paris."* 



The genus or subgenus Calyptropsis, proposed by Tate,t does 

 not seem to diifer from Siga^jatella, created by Lesson for the 

 reception of this species. t 



A few specimens from 63-75 fathoms off Port Kembla.

A broken shell, 30 mm. in diameter and apparently half grown, 

 corresponds with actual fossil shells from Muddy Creek, with 

 which I have compared it. This identification adds to the recent 

 fauna another Tertiary survivor. 



From 63-75 fathoms off Port Kembla ,• from 54-59 fathoms off 

 Wata Mooli ; and lately taken by Mr. G. H. Halligan and myself 

 in 100 fathoms sixteen miles east of Wollongong.
