I Stat. 258 are the only ones which have been ■< ill<it»-.l alive, with 



the operculum, which is calcareous, as has been stated by \. Martens (Rumphius Gedenkboek, 

 Moll. p. Menke (Syn. meth. Mollusc. Ed. alt. [830, p. 47) has not described it, bul locates 

 it in liis Section B * Ventricoso-globosae ; operculo (in omnibus?) corneo". Tryon (l.c.) locates it 

 amongst the species with corneous operculum. As Menke lias not described his species 1 have 

 applied Bi unvtlle's name, which has priority, though he gives no more description thau Menke. 

 Perhaps the name lupinus of Deshayes (An. s. vert. Ed. 11, Vol. VIII, p. 648) will be the 

 • •Kiest name accompanied by a description.

Philippi has separated this form as a valid species. The Siboga-specimen exhibits all 

 ti 1 ters, but I think they are only vanetal. Tryon Man. of Conch. Vol. VIII, p. 21), 



quotes it simply a^ a synonym. The specimen is about as small as Philippi's fig. S, and possesses 



the fine, sulcated operculum.

Many authors have considered .\ . euzona to be merely a variety or even a synonym of 

 .V. picta Reclu: the Siboga-specimens belong without exception to euzona, I have applied 



tliat name. Anatomy perhaps will produce distinguishing characters.
