GARRETT: ON POLYNESIAN MITRID^. 55 



dark red to deep brown-black. Our largest specimens are 

 the same size as Mr. Reeve's figures of Philippine shells. I 

 obtained some fine examples at the small group of Aiou 

 Islands near Waigion in the eastern part of the Moluccas. 



130. Turricula Pacifica Reeve, 1. c, pi. xxxiii-, fig. 272. 



Not uncommon, buried in sand in shallow water, inside 

 the reefs at the Paiimotu, Society, Samoa, Viti, and Kings- <>U 

 mill Islands. / 



The brown band, which is seldom continuous, usually 

 consists of a row of small spots, which are frequently nearly 

 or quite obsolete. The longitudinal ribs vary much in size 

 and number, and some of the forms gradually pass into T. 

 cadaverosa, with which it is more nearly allied than with 

 exasperata, as stated by Reeve. 



131. Turricula plicata Klein. Reeve, 1. c, pi. viii., fig. 56. 



A single perfect adult and a young example was found 

 buried in sand at the Caroline Islands. 



The adult specimen, which is one-fourth smaller than 

 Mr. Reeve's figure, is not nearly so gaudily colored, but 

 agrees precisely in coloration as mentioned in his description. 

 He does not allude to the transverse impressed lines, which 

 are very distinct. 



132. Turricula porphyretica Reeve, (?) 1. c, pi. xxv., fig. 

 195. — T. ventricosa, Garr. MS. 



A very rare species, of which we obtained two examples 

 on the outer reefs at the Samoa and Viti Islands. 



Our two shells, which are a little larger than Reeve's 

 figure of a Philippine example, agree very nearly in shape 

 and sculpture with the above species. The Viti specimens 

 are differently colored, the ribs smaller, more numerous and 

 are distinctly striated with spiral impressed lines ; the latter 

 character is neither alluded to in the text or represented in the 

 figure. However, after some hesitation I have adopted
