204 Mr. L. Reeve on two new species of Shells from Cambojia. 
is the colouring. In H. Brookei the lower half of the whorls is 
of a uniform dark chestnut-colour; in H. Mouhoti it is pure 
white, turned to a bright straw-colour by the overlying of a 
shining horny epidermis, encircled immediately below the peri- 
phery by a broad, rich, purple-black band, somewhat like the 
bands of the large Philippine Bulimus Reevei, but even broader 
and more defined on the white ground. The region of the um- 
bilicus is also deeply and as definitely stained with the same 
purple-black colour. As in H. Brookei, all the specimens of H. 
Mouhoti are sinistral, or what is more commonly called reversed. 
Bulimus Cambojiensis. 
Shell either sinistral or dextral, cylindrically ovate, thick, 
stout and pupoid in the spire, bluish-white, tinged with a watery 
fawn-colour, and clouded throughout with oblique zigzag flames 
of the same colour, darker, but very undefined and washy ; 
whorls seven, smooth, rather bulbous, faintly impressed concavely 
below the suture ; aperture ovate, of rather moderate dimensions, 
overlaid in a very conspicuous manner across the body-whorl, 
and over a very thickly reflected lip, with a callous, opake, milk- 
white deposit, which in the interior is stained with a beautifully 
iridescent violet-rose. 
This fine species, of which Mr. Stevens has received several 
specimens, measuring nearly 3 inches in length by 1 inch in 
width, is a most characteristic example of a type of the Malayan 
province of the genus, represented by the old Bulimus citrinus 
of Bruguiére; and I name it after its well-authenticated place 
of habitation, because the species is, in all probability, confined 
to that locality. The islands adjacent to Cambojia have been 
pretty well ransacked; and we have nothing like it in species, 
either from them or from the contiguous mainland of Siam on. 
the west, or Cochin China on the east. This particular type of 
the genus appears, however, abundantly at the Moluccas, in B. 
citrinus ; and at Mindanao, the southernmost of the Philippine 
Islands, in B. maculiferus. Like these two species, B. Cambo- 
jiensis occurs with the shell convoluted either to the right or 
to the left. The shell is both larger and stouter than that of 
B. citrinus, differently painted, and especially characterized by 
its mouth of iridescent violet-rose, or what is now fashionably 
termed “ Solferino”’ colour.
