Var. a. White, with a yellowish epidermis, a very dark brown, 

 almost black, antesutural band, and a rather broad, black band sur- 

 rounding the columella. 



Var. b. The same as the last, with an additional broad interme- 

 diate anterior black band. 



Var. c. Similar to the last, with the addition of a black band an- 

 terior to the sutural band, and with the anterior intermediate band 

 much wider. 



Varieties a, b, c, are all found at Puerto Galero. 



Var. d. Nearly black all over, and only showing more or less di- 

 stinct remains of white on the three first volutions ; epidermis very 

 thin and nearly colourless. Found at Calapan, in the Island of Min> 

 doro. 



Var. e. Of a dark chestnut-brown colour, with the same arrange- 

 ment of colour as the last, but covered with a thickish, brown, opake, 

 hydrophanous epidermis. From Puerto Galero. 



I am compelled to regard as a variety of this species a shell which 

 Mr. Cuming has brought from the island of Tablas, whose spire is 

 more elevated, having nearly five volutions ; it is of a dark colour, 

 with more or less distinct lighter bands, and the same thickish, 

 brown, opake, hydrophanous epidermis as the last : its columella, 

 and the columellar lip, are of a brownish purple. I designate this 

 as Var. /. 



The figure given by De Ferussac represents a rather dwarf vari- 

 ety, of which I have seen a specimen in Mr. Metcalfe's collection.

The subconical form of the spire, with very slightly ventricose 

 volutions, distinguish this from all its most nearly-related species. 

 When young it is slightly carinated. The anterior part of the last 

 volution is usually coloured of a pale yellowish tint.

 tenuis, alba, subhyalina ; spird subacuminatd, obtusd ; anfractibus

Long. 1 ; lat. 1 poll. 



Hab, prope Mansalai ad insulam Mindoro, Philippinarum. 



Var. b. fasciis duabus castaneo-nigris. 



Nearly related to the last {H. ignobilis) : it may be distinguished 

 by being rather smaller, by having its volutions rather more convex.
