Of the four bands upon the body-whorl the posterior and 

 anterior are thicker than the other two. The termination of 

 the anterior zone forms a conspicuous red spot at the end of the 

 labrum, and there is a similar spot upon the anterior columellar 

 fold, which is the largest of the four, the others diminishing 

 in size.

This species and the variety cancellarioides have been 

 recorded from Mauritius, Red Sea, China, Philippine Islands, 

 Lord Hood Island, the Paumotus, etc. 



It bears the name of M. nodosa Swainson in the mono- 

 graphs of Reeve, Sowerby, and Tryon. Reeve (1844) states 

 that " it was described many years since in the ' Philosophical 

 Magazine' by Swainson," and Tryon (op. cit. p. 229) gives 

 the reference " 'Phil os. Mag.,' 401, 1823." On referring to 

 that work I find a paper by Swainson, but certainly no mention 

 of a Mitra nodosa. Swainson did, however, make use of 

 the name nodosa in his ' Treatise on Malacologv ' (1840), p.
