Plate I. 



Oeuus LAMPANIA, Gray. 



Testa suhjlnvialilis, clavata ; aiifractibus brevibus, fiimtis, 

 dor so pier mn que siibarciialo ; aperhirdinfra subproiliic- 

 td, canaVi vix rHstiitcto ; opercnlo c.orneo, MuUhpirnll. 



Shell subfluviatile, club-shaped; whorls short, turreted, 

 back generally somewhat arched ; aperture rather pro- 

 duced beneath, canal scarcely distinct ; operculum 

 horny, multispiral. 



There really are no characters by which this jrronp can 

 be defined, so as to distinguish all the species that belong 

 to it from all others. When placed in a drawer, these 

 species appear to belong to each otlier rather than to 

 other groups, but for what reason can scarcely be ex- 

 plained, except it be that in the typical species the back 

 is somewhat arched, and the ajjcrture is bent forward in 

 front, so as in some measure to obliterate the canal, and 

 that in these characters most of the species more or less 

 agree. The greater part are Australian shells, with one 

 from China, and one or two from the Philippines.

 ferous on the plaits, the last angular in the middle, 

 nodosely ribbed beneath the angles; aperture subtri- 

 gonal, outer lip angular.

A curiously angular shell, which seems to agree in generic 

 character better with this thai\ with other groups.

The ink-bottle Lampania. Shell subpyramidal, black 

 or black-spotted, spirally sulcated ; whorls inflated in 

 and beneath the centre, white at the suture, columella 

 white, arched, short, outer lip rounded.

Distinguished from the other species by the inflation of 



the lower part of the whorls.

The Australian Lampania. Shell rather ventricose, 

 blackish, white-banded, longitudinally plaited, spirally 

 girt with beaded ribs; whorls somewhat rounded, 

 erenated at the margin ; aperture obliquely subquad- 

 rate, outer produced in the centre, scarcely emargi- 

 nated at the columella.
