32 JOURNAL OF CONCHOLOC V, VOL. 15, NO. I, JANUARY, I916. 



On May nth, 1869, at Stevens' Auction Rooms, in King Street, 

 Covent Garden, was sold the fiist portion of the late Mr. G. F.- Angas' 

 celebrated collection of Mollusca (sale no. 3186). Lot 92 was cata- 

 logued thus : — 



"Two white variety of Haipa ventricosa, and a beautiful rose- 

 " tinted one." 



I was present on this occasion, and shall never forget the beauty 

 of these shells. Two of them were of the purest white, perfect albinos, 

 live, shining, and polished, the third very finely tinted with rose. 

 They were purchased by my friend, the late Mr. Allan Harvey Drum- 

 mond, for Lady Harriet Ramsden, who then lived in Portman Square, 

 and possessed a very select conchological cabinet. She died in Nov- 

 ember, 1873, and her collections were dispersed; but I have never 

 been able to trace these wonderful shells, which live in one's memory 

 as perfect. 



I esteem H. caln-itii Fischer (/. de Couch., viii., pi. iv., f. i, 2) to 

 be a dwarf, compact form of this species, with the callous columellar 

 deposit not sufficiently thickened so as to modify the many ribs of 

 the earlier whorls. It is a very beautiful form, and I possess two 

 fine specimens. 



3. — Harpa conoidalis Lamarck.

Harpa ventricosa Lamk. var. L. C. Kiener, Coq. A^iv., p. 6, pi. v., f 4. 



Harpa ventricosa var. Deshayes, Encycl. Meth., A^ers, ii., p. 186. 



Harpa conoidalis Lamk., Tryon, Man. Conch., v., p. 98, pi. xl., f. 61. 



Habitat : Philippine Islands, Mauritius, Indian Ocean generally. 

 .Confounded with ventricosa Lamk., till that author finally differen- 

 tiated it, this species differs in greater obliquity of whorl, and sloping 

 crescent-shaped' outer lip. Substance lighter, with callous deposit of 

 columellar enamel less pronounced. Character of painting variable. 

 Ribs almost as in ventricosa in painting, l)ut thinner and less pro- 

 nounced as a rule, never overlapping, shining, carneous. 



This species certainly seems a link between ventricosa (^niajor) and 

 articularis [davidis), possessing attributes of both. All the so-called 

 conoidalis, with decided revolving articulated markings on the ribs, I 

 should call a/ticidaris. Typical conoidalis is, as regards its costal 

 painting, very similar to ventricosa. I consider nabliuni Mart, and 

 ligata Menke, therefore, to belong to the next species.
