 In giving the above synonymy of L. aquaiile, I have accepted 

 the opinions of and quoted from Dall (7, 227) and Tryon (36. 12). 

 Not having specimens of some of them I am unable to judge for 

 myself. The inclusion of T. americanum, D'Orb., seems doubtful, 

 since Watson (39, 390) regarded it as a synonym of L. costatum, 

 Born. I have recovered the exact date of the publication of the 

 Mollusca of the Sulphur from Pace's admirable work on the 

 Columhellidce (26). In arriving at the above conclusions I have 

 had the advantage of consulting with Mr. C. Hedley, and they 

 may, therefore, be regarded as a joint opinion. 



LoTORiuM QUOYi, Reeve. 



I cannot agree with Pritchard and Gatliff {op. cit.) that this is 

 only a form of L. verrucosum, Reeve; and that the name should 

 be relegated to the synonymy thereof. Than that species L. 

 quoyi is smaller, has flatter whorls, is more regular in growth, 

 has a slightly smaller and higher protoconch. The body whorl 

 of quoyi is sculptured by revolving and transverse riblets of equal 

 strength, seven of the former and nineteen of the latter. Z. 

 verrucosum has six of the former and eleven of the latter, these 

 being twice as strong as revolving riblets. This sculpture gives 

 L. quoyi a beaded appearance which the other species does not 

 possess. They were always treated as distinct species by Prof. 

 R. Tate, whose acquaintance with them was almost life-long. 



LoTORiuM RUTiLUM, Menke. 



This species, considered by Reeve to be synonymous with L. 

 labiosum, Wood, has lately been identified by Mr. C. Hedley 

 from the type locality. He finds that it is a valid species, and 

 has in preparation a note on the subject.
