GARRETT: ON POLYNESIAN MITRID^. 23 



42. Mitra peculiaris Reeve. Conch. Icon., pi. xxxvi., fig. 305. 



Two dead specimens found on the shore reef at Kioa, 

 Viti Islands. 



They agree in every particular with Reeve's description 

 and figure, except in having fine spiral incised lines and one 

 more columellar plait. 



43. Mitra pontificalis Lamarck. Reeve, 1. c, pi. iv., fig. 23. 



Occurs in more or less abundance in all parts of Poly- 

 nesia. The spiral punctures are not constant. 



Animal creamy- white, with opaque-white dots. 



44. Mitra peregra Reeve, 1. c, pi. xxiv., fig. 186.

 2ro. Mitia (Pusia) coriacea Paetel (not of Reeve); Cat. 

 Conch., p. 39. 



Under coral en reefs. Excepting the Marquesas and 

 Cook's Islands, occurs in all the South Sea groups, but more 

 abundant at Samoa and the Viti Islands than elsewhere. 



I don't think there is much, if any doubt in respect to 

 the correctness of the determination of this species, which 

 agrees very closely wilh Reeve's short diagnosis and tolerably 

 well with his indifferent figure. 



Perfect shells are dark reddish-chestnut, the spiral ribs 

 articulated with tawny-yellow, and the aperture is yellowish- 

 brown. Weathered shells are dark red and the costal spots 

 whitish. 



Society Island specimens, which Mr. Pease received of 

 me, were referred to Reeve's rotundili^-nta, which latter is 

 quite a different species. 



Miff a coriacea is more slender, and the sculpture and 

 color quite different from our shells.
