(45) Ajnastra porphyrostonia Pease. 



Amastra porphyrostoma Pease, J. Conchyl. xvir. (1869), p. 172 ; Hartman, P. Ac. 

 Philad. 1888, p. 48, pi. I. fig. 6. 



Hab. Oahu (Pease). 



(46) Amastra piillata Baldwin. 



Amastra pullata Baldwin, P. Ac. Philad. 1895, p. 228, pi. xi. figs. 31, 32 ; 



Gwatkin, t. c. p. 239 [radula]. 

 Amastra twibrosa Baldwin, t. c. p. 229, pi. xi. figs. 36, 37 ; Gwatkin, t. c. p. 239 



[radula]. 



After an examination of the long series collected by Mr Perkins I have been 

 unable to sever these two species. The animals are said to differ in colour, and they 

 are said to inhabit different districts ; conchologically they seem to shade into one 

 another, and the radula appears to be identical. Probably they will prove to be local 

 races.

 pjtUata) ; Kamalo and Makakupaia Mts. (Perkins).
