conspicuously granular, about every fourth one is larger 

 than the others. The color is a uniform dull brown, and the 

 longitudinal ribs are very conspicuous. The outer lip has a 

 varix, but is hollow within. The sinus is very faint, and the 

 canal a little produced and recurved.

This shell comes so close to Clathurella sculptilis Angas that 

 I shall best define it by describing the differences. The ribs 

 in our sj^ecies are double the number ; the sinus is not so 

 deep, and consequently the lines that it leaves by growth 

 near the suture are nearly straight, and they are not very 

 visible. There is no smooth space below the sutures, and 

 the lirss are very close and alternating, (In C. sculptilis they 

 are all of one size and distant.) The lines of growth are not 

 very visible. The nucleus in both species is white and finely 

 groved of 1\ whorls to where the normal sculpture of the 

 shell abruptly commences ; but in this species the groves are 

 finer, and there is no trace of transverse sculpture. In Mr. 

 Angas's shell it is coarse, and there are signs of sculpture. 

 Neither shells appear to be very uncommon. 



I must add to the Tasmanian fauna : — 



Clathurella eicolor. Angas. 



Clathurella sculptilis. Angas. 



Both of these shells have been hitherto found only in or 

 near Port Jackson. The Rev. Mr. Atkinson has found the 

 former at Circular Head and the latter at Long Bay, so we 

 may conclude that they both have a wide range, and probably 

 extend through Bass' Straits. They do not appear to be at 

 all uncommon.
