lO GARRETT: ON POLYNESIAN MITRIDiE. 



longitudinally striped with brown. Aperture whxte, with a 

 slight orange-brown tinge deep in the throat. 



The transverse ridges are rather sharp, their interspaces 

 with or without the smaller ridges, and longitudinally with 

 closely-set incised lines. 



It is closely allied to, but quite distinct from M. flammea 

 Quoy and Gaimard (not of Reeve), and M. interlirata Reeve. 



Paetel records it from New Caledonia. 



The animal is creamy white, profusely maculated with 

 small irregular opaque-white spots, and the anterior portion 

 of the foot, base of tentacles and siphon tinged with brown. 



4. Mitra astricta Reeve, 1. c, pi. xxiv., fig. 188. 



This somewhat rare species only occurred to my notice 

 at the Sandwich and Marquesas Islands, where they were 

 found near low water mark on rocky coasts. 



The color varies from light yellowish-brown to olive- 



f.i brown, with or without the fi^e transverse brown lines and 



j subsutural pale band mentioned by Reeve. The surface is 



more or less striated parallel to the axis of the shell, and the 



upper whorls are finely granulated. 



5. Mitra amphorella Lamarck. Reeve, 1. c, pi. xii., 83a, 83b. 



Not uncommon at the Viti, and very rare at the 

 Panmotu Islands, where they were found beneath masses of 

 dead coral on the shore or fringing reefs. 



yji Viti examples which are larger than Panmotu specimens, 



/ differ considerably in the size of adults, which in shape are 



about intermediate between Reeve's two figures, which are 

 colored precisely the same as our shells. The spiral incised 

 lines or grooves are generally obsolete on the middle of the 

 body whorl and are either simple or punctated. 



It is frequently referred to the genus Strigatella ; but as 

 none of my examples exhibit the peculiar peristome of that
