22 THE VOYAGE OF H.M.S. CHALLENGES. 



The following Chitons also have blue spots : Cliiton magnificus, Desh., and Chiton 

 disjunctus, Fremb. The latter is also from Valparaiso, but it would be impossible to 

 mistake these for Chiton murrayi. 



Superficially, this species bears some resemblance to Lepidopleurus lentiginosus, Sow. 

 (G. B. Sowerby, 1840, Charlesworth's N. S. Loudon's Mag. Nat. Hist., and Conch. Illust., 

 1841, figs. 120, 121 ; Reeve, Conch. Icon., 1847, pi. xxiv. fig. 165 = Cliiton cyaneopunc- 

 tatus, Krauss, Die siidafrikanischen Moll., 1848, pi. iii. fig. 2) ; but apart from the 

 generic distinctions, Sowerby's species can be distinguished by the perfectly smooth shell, 

 inconspicuous lateral areas, paler colour of the shell generally, and absence of the external 

 black border to the blue spots. I have given myself the pleasure of dedicating this pretty 

 and distinctive little Chiton to Mr John Murray of the Challenger Expedition.

Half-a-dozen specimens of this pretty little Chiton were collected. Blainville's descrip- 

 tion is not very good, but it is sufficiently exact to justify the retention of his name.
