present knoAvn. Some of the smaller shells are not easily 

 distinguished from species occurring in the Eastern 

 Archipelago, Japanese, and E. Australian seas, and no 

 doubt as dredging operations are pursued, these re- 

 semblances will be found still stronger. The number of 

 species especially of the smaller forms in Tasmania would 

 be surprising were it not remembered that it is almost a 

 warm sea, with many islands, an extensive coast line, and 

 an almost uninterrupted littoral connection with coral seas 

 within the tropics, and, we may add, almost with the 

 Indian Archipelago,

It is sufficient to say of this shell that it is a small white 

 species of the peculiar form of Murex common iu South 

 Australia and formerly common in Europe, during the 

 earlier tertiary periods. It is distinguished by a conspicu- 

 ous broad brown zone on a white ground. The three wing 

 like varices are not very much expanded. Flinders Island.

No. 2. Typhis aecuatus. Hinds. Voy. Sulphur. A small 

 specimen of this shell has been dredged from 10 fathoms 

 sand by Eev. H. D. Atkinson at Long Bay. It is paler than 

 the described species, smooth ^vith rounded broad varices 

 which are bent back so as to become confluent with the tubes 

 which crown the ^yhorls.
