 p. 136. 



Station 49. 



I submitted a specimen, dredged by Mr. G. H. Halligan and 

 myself in 100 fathoms, sixteen miles east of Wollongong, to Mr. 

 W. L. May, who, having compared it with the type, writes (27 

 July, 1903): — "The shell (from Wollongong) is just about the 

 same form as ours {i.e., the Tasmanian), though smaller; it how- 

 ever differs considerably in detail, it has flatter and more tabulated 

 whorls, and the whole shell has a sharper, more clean cut 

 appearance. The ribs are about the same, only more distinct, 

 but whilst in our shell the cross sculpture consists of fine close 

 strise, this has sharp little keels, separated by an appreciable 

 interval, and therefore very much less numerous. It might 

 perhaps be considered a distinct variety." 



Two young shells from 63-75 fathoms off Port Kembla. 

 Previously dredged off Cabbage Tree Island, Port Stephens.
