. Station 13. 



Shell acicular, smooth, glossy, transparent or opaque, without 

 varices. Colour : the opaque or semitransparent shells are milk- 

 white, with a dull opaque band above the sutures, 

 next above which is an indistinct, often inter- 

 rupted orange line ; another orange line runs 

 round the periphery of the last whorl and tinges 

 the outer lip. Whorls twelve, with straight 

 sides, parted by a linear suture. Base attenu- 

 ated. Aperture rather oblique, narrowly pyri- 

 form, effuse anteriorly, posteriorly subchannelled, 

 a thin callus on the body whorl, columella 

 slightly curved, thickened within. Length, 

 7"7 mm. ; breadth, 1*2 mm. 



This species has a general resemblance to L. 

 bivittata, H. & A, Ad.,* but as that is described 

 as having from nine to ten whorls in a length of 

 14 mm., I consider it distinct. Mr. W. F. 

 Petterd has kindly identified my specimen as 

 his Eidima vitrea, of which the description suits 

 a half grown L. lodderie. The decision of Tate 

 k, Mayt that E. vitrea, Petterd, is Leiostraca 

 bivittata seems to me not in accord with the 

 proportions noted for each. Other allied species 

 are Leiostraca samoensis, Crosse, I longer, and in proportion much
