312 MELVILL AND STANDEN : SHELLS FROM LIFU. 



phery, the middle keel being strong, squarely built, and bold 

 and projecting further from the whorl than the two other keels. 

 Shell much depressed, apex papillary, sunk in the spire ; spiral 

 crenellas run round the sutures and round the peristomial 

 callosity, this being tongue shaped and well nigh concealing the 

 umbilicus. One specimen only, discovered in the mouth of a 

 larger shell by the Rev. Lewis Shackleford. 



Alcyna lifuensis sp. nov. (PI. XL, fig. 76). 



A. testa imperforata, minuta, solidiuscula, parum nitida, 

 anfractibus quinque, quorum apicalibus late puniceis, tribus 

 ultimis albis, transversim interrupto-lineatis, linen rubris, 

 ultimo anfractu infra, juxta suturas, squarrosc regulariter 

 albispatiato, et apud peripheriam continue rubra linea spatio 

 simili alternate), apertura rotunda, labro exteriore subexpanso, 

 columella ad basim fortiter unidenticulata, denticulo acuto. 

 Long., 175, Lat., 1 mill, 



.Smaller than A. rubra Pease, and differing from all the 

 forms we have seen of it, and likewise of the Japanese A. ocellata 

 A. Ad. in the whorls being plainly five in number, and in the 

 different pattern of the interrupted red lines, the shape being more 

 effuse than A. ocellata, and the shell smaller than in A. rubra. 

 There seem affinities with A. lineata Pease from the Hawaiian 

 Islands, of which we have only seen a description, but here the 

 whorls are fewer, the lip is not thickened out, the apex is pink, 

 not white. Though small, it is a very brightly coloured little 

 shell, being five whorled, the whorls slightly swollen, white, with 

 transverse interrupted red lines encircling it spirally, round the 

 periphery these lines are regularly interrupted, leaving equal 

 white spaces, below the suture on the last whorl are square 

 white spaces left bare, the mouth is round, lip slightly effuse, 

 plain ; the columella having a very strong tooth near the base. 



Minolia agapeta sp. nov. (PI. XL, fig. 77). 



M. testa minuta, effuso-conica, albida, solidiuscula, anfracti- 

 bus quinque, turritis, infra suturas angulatis, spiraliter
