150 Gatliff and Gahrid : 



The forms described under the two above names have been 

 considered by some to be varying forms of one species; ours is 

 that described by Lamarck. 



Genus Cantharidus, Montfort 1810. (Phasianotrochus, 

 Fischer 1885, is a synonym.) 



Cantharidus exjmius, Perry. 



This name replaces that Hsted as Phasianotrochus carinatus, 

 Perry, who called it a Biilimus, and the name B. carinatus had 

 ieen previously used by Bruguiere. 



Cantharidus nitidulus, Philippi. 



1849. Trochus nitidulus, Phil. Conch. Cab., p. 295, No. 

 383, pi. 43, f. 10. 

 Hab. — Portland, and off cable to Tasmania, Bass Strait. 



Genus Calliostoma, Swainson 1840. 



Calliostoma armillatum. Wood. 



1828. Trochus armillatus, Wood. Index Test. Supple- 

 ment, pi. 5, f. 5. 

 1901. Callioistoma meyeri, Phil. Prit. and Gat., these 

 Proc, V. XIV., p. 134. 

 Wood's name was not previously adopted, because there was 

 no description of the shell. The rules of the International Con- 

 gress now allow a binomial name, accompanied by a figure to be 

 sufficient. 



Calliostoma comptum, A. Adams. 



1913. Calliostoma comptum, A. Ad. Hed., P.L.S., 

 N.S.W., V. XXXVIIL, p. 279. 

 This species was listed as C. poiipineli, Montr., from New 

 Caledonia. Upon consulting the original description of that 

 •species we find that it is distinct from ours. 



Genus Cantharidella.Pilsbry 1889. 

 This genus includes the shell listed as Gibbula tiberiana, Crosse. 



Genus Calliotrochus, Fischer 1880. 



This includes the shells listed as Gibbula tdsmanica, Petterd; 

 and G. Icgrandi, Petterd.
