24 GARRETT: ON POLYNESIAN MITRIDiE. 



It belongs to the section or subgenus Chrysame, not 

 Turricula nor Fitsia. 



45. Mitra pellis-serpentis Reeve, 1. c, pi. x., fig. 66. 



A rather scarce shell found under dead coral on the 

 outer reefs in all the eastern groups except the Marquesas. 

 We also obtained it at the Kingsmill Islands. 



Society Island specimens, which attain a much larger 

 size than Reeve's very accurate figure, vary considerably in 

 the small decussated ridges, which become nearly obsolete 

 in some individuals. All are densely striated parallel to the 

 axis of the shell. 



As previously stated, it is connected with M. bnimalis 

 by intermediate forms. 



46. Mitra papal is Linnisus. Reeve, 1. c, pi. ii., fig. 9. 



This is a very rare South Sea shell, and only occurred 

 to my notice at the Kingsmill and Caroline Islands. Mr. 

 Reeve on the authority of Cuming gives Anaa, Pa^motu 

 Islands as its habitat. I very much doubt its occurrence 

 there; at least after several months exploration in a dozen 

 different islands of that group, and the examination of many 

 collections made by others, I failed to disco- er a single 

 specimen. 



47. Mitra procissa Reeve, 1. c, pi. xxii., fig. 177. 



A few examples occurred under coral on the outer reefs 

 at Samoa and Viti Islands. 



Our shells are a little smaller and a trifle more robust 

 than Reeve's figure, though in every other respect they 

 accord closely. 



48. Mitra robusta Reev^e, 1. c, pi. xviii., fig. 140. 



We obtained this interesting species beneath large 

 water-worn lava stones on rocky coasts, Viti Islands. They 

 were all found in the upper half of the littoral zone, associated 

 with Patella, Littorina and Nerita. It appears to be very
