afforded him excellent opportunities of observing this species, 

 and he records very full particulars of its varieties and distribu- 

 tion. I have been in accord with him for a long time in assign- 

 ing glutinosa Pfr. to varia. I think Pfeiffer at one time claimed 

 Reeve's fig. 17 &, pi. 3, Monog. Part., as his glutinosa. This fig. 

 represents the shell in Coll. A. N. S. labeled P. strigosa Pse. 

 ex auctore. The latter, however, is a Marquesas shell, which I 

 have recently discovered to = a dark variety of recta Pse. 

 See recta Pease.
