Smith for his Pleurotoma toyresiana^' that repeated comparison 

 confirms me in the belief that both names are based on the same 

 shell. If this be so, priority must be awarded to Watson, whose 

 preliminary description! of this Torres Straits shell appeared on 

 November 3rd, 1881.

 Messrs. G. Gross and C. J. Wild, who have frequently collected 

 the species in and around Moreton Bay, consider that Conns 

 innotabilis Smith | intergrades with C. coxeni. They showed me a 

 series of intermediate forms, in which the spire was more or less 

 elevated and the spiral grooves on the shoulder were more or less 

 developed.
