204 LATIAXTS. 



R. Eugeniae, Bernard!, R. nodosa, Ad., and R. tortilis, Ad., are 

 referred to this species by Dr. Gray in a short paper in Ann. 

 Mag. N. H., 1867, in which, in a single paragraph, R. Mawse is 

 referred to as R. Mairae, R. Eugeniae quoted as of Beraud instead 

 of Bernardi, and R. textilis substituted for R. tortilis, Ad. ; whilst 

 the adopted name, quoted as R. pagoda, Johnson, instead of R. 

 idolea, Jonas, caused me to hunt up all the Johnson papers con- 

 tained in the Royal Soc. Catalogue. Dr. Gray remarks that these 

 so-called species are founded on single variations, such as the 

 presence or absence of a keel on the body, nodose plications, etc. 

 R. Eugeniae only has been figured (tig. 343). I venture to add 

 Pyrula fusiformis, Chenu, which appears to agree well in its 

 characters. 



R. FORTUNI, A. Ad. 



Not figured, and no dimensions given. It is widely umbili- 

 cated, imbricated, pink in color, and may be a variety of R. 

 Mawse. 



China. 

 R. RHODOSTOMA, A. Ad. PI. 64, fig. 347. 



Yellowish-brown, with white bands ; pink within the aperture. 



Length, 1'38 inches. 



China. 



The aspect of this species is so decidedly that of a Turbinella, 

 that, although no folds are depicted on the columella, or described, 

 I suspect that it really belongs to that group. In a series of T. 

 carinifera, Lam., in the collection of the Philad. Acad., occurs 

 an abnormal specimen entirely similar in the wide, carinated 

 umbilicus. 



R. TURRIS, Morch. PI. 65, fig. 351. 



This was described as a Goralliophila, but its similarity to R. 

 rhodostoma is sufficiently close to make it probable that it may be 

 more properly arranged in the group of Latiaxis. 



Length, 1'75 inches. 



Hob. uiik'notcn ; probably coll. near Montevideo, /S'. Am. 



R. ELEGANS, Angas. 



This species, described in 1878, and well figured, is another of 

 the numerous synonyms of Rhizochilus bracteatus, being equiva- 

 lent to the var. babelis.
