I find the length of the pectoral fins very variable and quite unreliable as a specific character. There is certainly no correlation between the length of these fins and the form of the dental laminae in the specimens examined by me, and it would appear that the two species callorhynchus and smythii cannot be maintained on the basis of these characters. It is probable that

It is probable that the examination of an adequate series of specimens would show that the nominal species capensis, from South Africa, and milii, from Australia, Tasmania, and New Zealand, are nothing more than varieties of C. callorhynchus. 1 The same condition is to be seen in a specimen of 550 mm. from off the coast of Uruguay (Marini).
