GARRETT: ON POLYNESIAN MITRID.Ii. 25 



local and abundant at the above group and very rare at Samoa. 

 They vary in color fromcinnamon-brown through all the 

 intermediate shades to deep blackish-brown, and in shape 

 from ovate to ovate-oblong. The latter form differs none 

 from Reeve's description and figure of M. Woldeniarii, 

 which is very closely allied if not identical with our shells.

A very rare species found under dead coral on reefs at 

 Samoa and Viti Islands.

Not uncommon under dead coral and in crevices on 

 reefs, at all the Western groups. 



This species has been confounded with virgata Reeve, 

 and both with paupercula L. They are nevertheless quite 

 distinct. The two latter belong to the genus Strigatetla, and 

 the species now under consideration is a true Mitra as 

 restricted, and will fall in the section or subgenus Ahbularia. 

 It is in faci much more nearly related to M. licaonica than 

 to the above two species, with which it has been united. 



It is rather surprising that Mr. Reeve should have 

 figured it to represent in part his virgata (fig. i97<s'). His 

 fig. 197^, which is quite a different species should retain the 

 latter name. Dr. Chenu's figure is an exact copy of Reeve's 

 fig. 197a. 



The latter author's retusa, fig. 199, has very much the 

 aspect of a weathered or rubbed shell, and agrees exactly
