1906.] MOLLUSKS FROM THE PKRSTAX GULF. 819 



T.murrayl iSinith * from Cape York, Australia, at 155 fatlioms 

 (by a curious coincidence the same depth of sounding-). Indeed, 

 we were at first inclined to consider them both identical. The 

 author, however, of T. inurrayi convinced us that while similar 

 in texture, pattern, and size, it differed in form, being moi'e nearly 

 equilateriil, the umbones in our species also less prominent though 

 acute, while the postei-ior portion of the dorsal margin in T. 

 murrayi is more decidedly excavate. Half-vM,lves only occurred, 

 some of them in quite fresh condition. All are of much the same 

 size, and we do not think the species could attain much larger 

 dimensions than those given.
