Hah. — Dredged with the animal. Half Moon Bay, Port Phillip, 

 also Western Port. 



Ohs. — Tryon's fig. 86 loc. cit. is a copy of that in Thes. Conch., 

 and is referred to in the text and table of the plate as 86, but 

 on the plate is wrongly numbered 85, and that of T. carinata 

 86, evidently a reversal, in error. Medley's fig. 26, plate 52 loc. 

 cit. does not represent the species. He states : *' A scar on the 

 summit, which suggested the name, was an individual and acci- 

 dental feature of the type shell. It is by chance repeated in a 

 specimen before me, and was probably caused by adherence of 

 a Capuliis, or some such associate." 



We have obtained over 20 specimens, some of them dredged 

 with the animal, all with the summit free from any encumbrance, 

 and we also have similar specimens from South Australia, and 

 cannot agree with Hedley's surmise. 



The habitat of the type is given as Philippine Islands; it is 

 more coarsely sculptured than as we find it.
