which recommence, however, below, towards the base, in many thin, 
almost straight, yellow lines. Mouth simple, narrowly oblong,

A short stout conical little species, of ivory whiteness, and quite 
smooth, lip denticulate within, and columellar four-plaited. Allied to 
M. minuta (Pfr.) and M. lavalleana (D’Orb.), with neither of which 
it seems exactly to correspond.

Hab, Bombay (Abercrombie). 
Two or three specimens of an unusually lovely little semi-transparent 
white species, occurring in shingle and shell sand from Bombay. The 
form is depresso-conical, white beaded, wonderfully closely obliquely 
striated at the interstices between the beading ; this is not distinguish- 
able without a lens, ‘The umbilicus has two rows of beads around it, 
one large with coarser gemmulz, very shining ; the other with smaller 
and more delicate granulation. Mouth thin, round, fimbriate, reflexed 
at the columellar margin. 
[N.B.—Another species of Solarium (Torinia), probably new, oc- 
curred with the above, allied to S. wrgatum (Hinds). This species is 
white, very depressed, quadrate, with similar transverse raised beading ; 
at the periphery the gemmule are larger and coarser, as also in the 
last row nearest the umbilicus at the base. Mouth simple, quadrate,
