6o GARRETT: ON POLYNESIAN MITRID^. 



from Samoa and the Pelew Islands. 



Our specimens are one-third smaller than Reeve's figure 

 of Philippine examples, but agree in every other particular. 



142. Turricula speciosa Reeve, 1. c, pi. xix., fig. 148. 

 This rare and handsome species occurred only in the 



condition of more or less perfect dead shells. They were 

 found on the outer reefs at the Cook's and Panmotu 

 Islands. 



Our shells differ none from Reeve's description and 

 figure of Philippine examples, except in the ribs being some- 

 what angular and nodulose next the suture; the latter 

 character though faintly expressed in the above mentioned 

 figure is not alluded to in the text. 



143. Turricula tusa Reeve, 1. c, pi. xxxiv., fig. 283. 

 This interesting little species which is rarely obtained, 



j^^ occurs under dead coral at the Pai^motu, Society, Sandwich 



and Samoa Islands. 



They accord in every particular with Reeve's description 

 and figure of a Philippine specimen. The upper third of the 

 body whorl and the spire exhibits large tessellations on a 

 white ground, the spots and lower portion of the body whorl 

 varies from reddish-brown to blackish-brown. A single 

 transverse white band marks the deep brown aperture. The 

 upper portion of the whorls are distinctly concave and the 

 ribs granulated. 



The animal is greenish-white, and beautifully marbled 

 with chocolate-brown. 



144. Turricula unilineata, sp. nov. 

 Shell acuminately turreted, subfusiform, rather slender, 



base contracted and slightly twisted, shining, brownish-lead 

 color with a single spiral whitish line on the upper portion of 

 the body; whorls 10, flatly convex, somewhat roundly 

 shouldered; longitudinally ribbed, ribs not very prominent
