GARRETT: ON POLYNESIAN MITRID^. 63 



T. incisa Garr. MS. 



A very rare Viti Island species, of which we found four 

 examples (dead), on the Kioa shore reefs. 



Having serious doubts of the correct determination of 

 this species I have added the MS. name by which it has 

 been known in my collection for the past several years. If 

 really distinct from Reeve's shell, and cannot be referred to 

 any described species my name can be retained. I add the 

 following description. 



Shell acuminately turreted, somewhat fusiform, rather 

 thick, slightly shining, base contracted, somewhat produced ; 

 color creamy-yellow, variegated with different shades of 

 ferruginous-brown disposed in a rude transverse band on the 

 body whorl and irregularly tessellated above; whorls lo-ii, 

 convex, last one faintly angulate above; longitudinally ribbed, 

 ribs small, numerous, convexly-angular, the same size as their 

 interspaces, and the whole surface with rather close deeply 

 incised spiral lines; aperture creamy-yellow with a faint 

 pinky tinge in front, a little less than half the length of the 

 shell; columella four plaited. 



Length 27, diam. 9 mill. (Coll. Garrett). 



Our shells though very nearly similar in shape are 

 considerably smaller than Mr. Reeve's figure of a Philippine 

 example. He describes the surface as being '•'■very finely 

 cancellated with rather flat closely set ridges of which the 

 longitudinal are the larger,^'' which will scarcely apply to our 

 shells, unless he considered the interspaces between the 

 incised lines to be ridges. 



149. Turricula sp. 



A single dead specimen found on the Kioa reef, Viti 

 Islands. 



It is a small elongate-oval species, cancellated with
