This is a delicately beautiful shell, curiously intermediate between 

 ! i<ut(ler Hanarias (Linne), and Scaphander puncto-ttriatut 

 (Migh), while perfectly distinct from both. In form it is less like a 

 Bulla than the latter, while the attenuation above is less, and the 

 expansion of the outer lip below is even greater than in the former. 

 Lying on its face, it is broader and is more flattened, and that, too, 

 more obliquely than either. Its puncto-striate spiral sculpture ap- 

 proaches that of Scaphander pundostriatm (Migh). Scaphander no- 

 />///> Verrill, is a good deal like, but then the proportion of the body- 

 whorl to the size of the mouth is greater, and the outer lip rises 

 higher and bends more to the left at the top of the shell ; the whole 

 shell, too, is narrower. (Wats.). 



S. MULTISTRIATUS Brazier. Unfigured. 



Shell white, thin, transparent, oblong ovate, transversely, obliquely, 

 and closely striated, attenuated towards the spire ; spire truncated, 

 slightly umbilicated ; aperture pyriform ; outer lip slightly inflated 

 above, from the centre to the base widely expanded a little thick- 

 ened ; columella obliquely somewhat faintly plicated. Length, 31 

 lines; breadth at spire, 1 line; at centre, If lines; base, 1J lines; 

 aperture circle at spire, H lines; at centre, 1} lines. (Braz.).

Shell thinnish, obliquely ovul, slightly narrowed and rounded 

 above, where the outer lip rises on the right like a tooth; in front 

 it is rounded with a very blunt anirulation at the point of the pillar; 

 ivory-white, glossy, striate, but scarcely stippled. The body is 

 rather tumid, and shaped like a Bulla. Sculpture: Longitudinals 

 there are exceedingly faint hair like lines of growth, of which, at 

 at frequent inti-miU, one more distinct produces a slight undulation 

 of the surface. Spirals the whole shell presents tin- microscopic 

 and vrry >uprrhVial crimping of the genus, which become rather 

 strong on the base; there are also some very superficial and 

 extremely obsolete bandings or furrows and ridges, which are
