slightly twisted, arcuate below, reflexed, expanded. Alt. Ss, greater

Off Sydney; S. Lat. 34° 13', E. Long. 151° 38' (Challenger). 



Bulla incommoda E. A. Smith, P. Z. S., 1891, p. 442, pi. 35, f.

The few spiral strire at each end are rather far apart with the 

 exception of those immediately around the umbilicus, which are 

 more approximated. (aS.). 



B. QUOYi Gray. PL 39, fig. 71. 



Shell oval, solid, indistinctly and closely marbled with fleshy pur- 

 ple gray on a pale ground, with two or three ill-defined encircling 

 zones of heavier, darker mottling. Surface smooth, but sculptured 

 toward the base by separated sjjiral grooves, becoming closer below ; 

 apical perforation moderately wide, either spirally grooved within 

 or nearly smooth. Columella with a moderate, lunate white callus ; 

 parietal callus thin. Interior whitish or fleshy. Alt. 25-26, diam. 

 16 mill.

 Man. N. Z. Moll., p. 121. Not B. quoyl A. Ad., Sowb. or Cpr. 



Well distinguished from other species of the southwest Pacific by 

 the spiral grooves at the base. 



B. PEASiANA Pilsbry, n. n. PI. 34, fig. 8. 



Shell ovately-oblong, thin, light, perforate; outer lip straight; 

 longitudinally finely striated, and marked with fine microscopic 

 spiral strise. Color chocolate-brown, mottled with darker, and 

 freckled and blotched with white. (Pse.). 



Sand'ivich Islands (Pse.). 



Bulla marmorea Pse., P. Z. S., 1860, p. 431. — SowB., Conch. 

 Icon., f. 16. Not B. mannorea Schroeter. 



The specimens before me are excessively similar to the West 

 Indian B. occldentalis ; in fact would be considered that were it not 

 for the difference in locality. Can the Sandwich Islands specimens 

 be ballast shells? The name of the species is preoccupied by 

 Schroeter.
