Catalogue of the Marine Shells of Victoria. 203 



Hab.— Western Port ; Port Pliillip ; Portland. 



Obs. — The colouration of this shell displays more variation 

 than any species that we know. Reeve remarks, "rather 

 obscurely clouded in respect of colouring which inclines towards 

 the base to form a tine network." In C. dictua this network 

 continues over the whole shell, but assumes the form of zig-zag 

 spiral lines ; when the markings take the form of an encircling 

 band it may be present on two of the apical whorls only, the rest 

 of the shell being white, or it may continue round all the whorls, 

 the 0. vincta being marked in this latter manner ; or the lines 

 and the reticulations may be present in the same shell ; or it may 

 be all white, salmon-red, or blackish-brown, or principally 

 lavender or yellow; or any of these may be the body colour, 

 with darker markings foriiiing encircling spots, bands, irregular 

 maculations, longitudinal flamings, or fine lines ; but the form is 

 faii'ly constant, the size varying from : length, 10 mm.; breadth, 

 4-5 mm., to length, 6 mm.; breadth, 2-4 m.m. 



Tryon rightly considers C. roblini, T. Woods, to be a synonym 

 of C. pulla, Gaskoin, but the shell he figures, quoted above, does 

 not answer to Woods' description, but is one of the many 

 varieties of C. nubeculata.
