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 1J 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 Bruguiere ; 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.
