GARRETT: ON POLYNESIAN MITRID^. 37 



white, banded with reddish-brown. Our examples, which 

 are, no doubt, somewhat faded, are the same color, and the 

 bands are always three, as represented in the figure. Living 

 shells are probably banded with dark brown or brownish- 

 black. 



84. Turricula assimiiis Garrett, Proc. Zool. Soc, 1872, p. 



481, 



A very rare species found under dead coral on the outer 

 reefs at the Cook's, Samoa, and Viti Islands. 



An oblong, subfusiform, shining species of a whitish 

 colour, with closely-set slightly-raised deep brown lines. 



85. Turricula angulosa Martini (?) Reeve, Conch. Icon., 



pi. xxviii., fig. 2 2 3«, 223^. 



I obtained many fine living specimens of this species 

 by digging in sandy mud, at low water mark in sheltered 

 places, at Vanua Levu, Viti Islands. 



Not being quite satisfied with the above determination, 

 I have marked it with a doubt. 



Our shells are a little smaller than Reeve's fig. 223a, 

 which they much more nearly resemble than the larger 

 figure, 223*^, which has the appearance of a distinct species. 

 He describes the colors as " light browfi, stained here and 

 there with brown spots' Viti examples are ashy-slate, and 

 all have a more or less distinct pale band just beneath the 

 sutural angle. The aperture is brownish, with a white zone, 

 and some have the throat bluish-white. The columella is 

 brown, with four or five pale plaits. 



The sculpture, which is very uniform and beautiful, 

 consists of about 20 narrow longitudinal ribs, which are 

 decussated with about the same sized but more crowded 

 spiral flattened ridges, which form crenulations at their points 

 of intersection and gives the whole surface a regular foveolate 

 appearance.
