54 GARRETT: ON POLYNESIAN MITRID^^ 



127. Turricula obeliscus Reeve, 1. c, pi. xv., fig. 107. 



Several dead examples of this rare species were found 

 on a sandy mud flat at Kioa, Viti Islands. 



All our specimens exhibit the same style of sculpture as 

 mentioned by Reeve, and are shaped exactly like his figure. 

 The most perfect examples are of a yellowish-brown color, 

 rather paler on the ribs, and all are encircled with the white 

 line mentioned by the above author. Three specimens 

 which are somewhat weathered appear to have been of a 

 . deeper brown than the typical color. 



The interspaces between the ribs are marked by rather 

 large closely-set transverse grooves. The largest example 

 which is the same size as Reeve's figure has 12 convex whorls 

 divided by a rather deep suture. 



128. Turricula purpurata Reeve, 1. c, pi. xxxiii., fig. 275. 



A few specimens of this pretty species were found on 



l/J the outer sandy beaches at Anaa, Paiimotu Islands. 



I Our examples which are more or less rubbed agree 



closely with Reeve's description and figure, except in being 



of a light pink color with traces of a white zone, and some 



seem to have had spots or streaks of the same color on the 



ribs. The description reads '■'■interstices iinpressly cancellated,^'' 



which term appears to signify that the impressed lines are 



interrupted by the ribs and not continuous as in our 



~ specimens. 



Notwithstanding the above discrepancy I do not hesitate 

 to consider our shells identical with the Philippine species. 



129. Turricula patriarchalis Gmelin. Reeve, 1. c, pi. xix., 

 fig. 146^, \\bb. 



A few dead specimens of this handsome species were 

 found washed up on beaches at the Samoa and Viti Islands. 



They differ considerably in the development of the 

 nodules on the shoulder, and the broad band varies from
