T. angasi, tasmanica, cana, ete.

This species, a tropical form, appears to come some dis- 
tance down the Eastern coast of Australia, but not to reach 
Victoria or Tasmania. It is found along the Western coast 
-of Australia, and at Albany on the southern coast. I have a 
recent shell from St. Francis Island, and Dr. Torr one from 
Wool Bay. 
At Murat Bay, in a subfossil form in a kind of con- 
glomerate on the beach, they are found in great numbers 
bearing their colour markings with Meleagrina fimbriata, 
Dunker, and Barbatia trapezia, Deshayes, neither of which 
is found in our waters alive, and in the same condition they 
-occur along the South Australian coastline to the east.

In Tate’s cabinet is an example from Wauralti, in Spen-

not yet taken it on the South Australian coast, nor has any 
-other collector to my knowledge.
