134 BUCCINID^. 



whilst tortuous as in Fasciolaria, it has at most a single fold in 

 lieu of the plaits on the columella of that genus. I have arranged 

 the subfamilies and genera, commencing with those most closely 

 allied to Fusus, and terminating with the truly buccinoid forms. 

 Although the range of form is great, it will be seen that the 

 transitions are not abrupt ; and in this case the lingual dentition 

 affords confirmation of the grouping adopted upon conchological 

 grounds. 



Subfamily MELONGENiNiE. Shell pear-shaped, heavy ; spire and 

 canal short. 



Subfamily neptuniin^. Shell rather thin, pear-shaped or 

 ovate ; canal moderate and twisted. 



Subfamily piSANiiNiE. Shell small, heavy, costate ; canal very 

 short and wide, outer lip thickened, dentate within ; columella 

 callous or rugose. 



Subfamily buccinin^. Shell rather thin, costate or smooth, 

 ovate, covered with a horny epidermis ; aperture very large, lip 

 thin, smooth within, terminating below in a short oblique notch. 



Subfamily EBURNiNiB. Shell thick, smooth, ovate-oblong ; 

 deeply umbilicated or umbilicus covered by a heavy callus ; 

 outer lip simple acute. 



Subfamily phot[n^. Shell small, smooth, costate or cancellate, 

 ovate or turreted, thick ; outer lip striate within ; canal short 

 and wide, columella twisted below. 



Subfamily MELONGENIIN^. 



Melongena, Schum. 



Syn. — Cassidulus, Ads. Galeodes, Bolt. Mancinella, Mus. 

 Berl. Myristica, Swn. Pugilina, Schum. Volema, Bolt. 



Distr. — 11 sp. West Indies, Panama, Red Sea, Philippines, 

 Australia, Polynesia. M. corona^ Gmel. (xlix, 3). 



Shell pyriform, solid, dark-colored or banded; spire short, 

 nodulose, spiny ; aperture oval-oblong ; canal short, open ; colu- 

 mella smooth ; outer lip simple. Operculum solid, claw-like, 

 nucleus apical, 



Kobelt, in his monograph of Pyrula (Conchy lien Cabinet), 

 adopts that genus, taking as subgenera Cassidulus (= Melon- 

 gena), Myristica, Pugilina, Yolema and Hemifusus. These 

 groups which (except the last) are too closely related concho- 

 logically as well as by their lingual dentition, Troschel also 

 places together, but without subordinating them to a higher 

 group. Pyrula would, indeed, be an excellent name on account 

 of its acceptance years ago for the major part of the species, but 

 unfortunately the first and only species cited b}^ Lamarck in his 

 original description of the genus is the Bulla Jicus, Linn., which
