46 GARRETT: ON POLYNESIAN MITRID^. 



perfect though dead condition on the outer reefs. 



The smooth shining surface, numerous narrow longi- 

 tudinal flexuous brown stripes on a bluish-white ground are 

 its most obvious characters. 

 io6. Turrlcula flexicostata, sp. nov. 



Shell acuminately turreted, rather slender, ashy-brown, 

 with a single narrow pale zone on the upper portion of the 

 body whorl, which is continued upward on the middle of the 

 whorls of the spire; whorls 9, convex, longitudinally plicately 

 ribbed, ribs narrow, smooth, flexuous; interstices with rather 

 close, transverse incised lines; base contracted, slightly 

 produced and somewhat twisted; aperture less than half the 

 length of the shell, brownish with a whitish zone; columella 

 with four plaits. 



Length 15; diam. 5 mill. (Coll. Garrett). ,

I A few more or less perfect dead specimens found on 



sandy beaches. 



As compared with obeliscus, the nearest allied species, 

 it is much smaller, differently colored, the ribs smoother, 

 more flexuous and the narrow pale zone is nearer to the 

 suture on the body Vv^horl and more distant on the spire. 

 107. Turricula festiva, sp. nov. 



Turricula fonnosa Garr. M.S. (not of Pease). 



Shell acuminately turreted, somewhat fusiform, cine- 

 reous, slightly mottled with ashy-brown; whorls 8, flatly 

 convex, anguiate beneath the suture, longitudinally plicately 

 ribbed, ribs narrow, rather closely-set, rather nodose on the 

 angle; interstices transversely striated with impressed punc- 

 tured lines; aperture elongate; columella with five plaits. 



Length 13 mill. (Mus. Godcffroy).
