43. Ovulum birostre (pi. c. f. 65, 66), Lamarck, Anim. 

 s. vert. vii. p. 370. 



O. testa elongata fusiformi, rosea, in medio albifasciata, vel 

 pallide fulva, in medio laevigata, sub-ventricosa, ad extremitates 

 striata, recti-rostrata ; apertura antice subaperta, labio externo 

 crasso, sub-flexuoso, postice ad canalem attenuato, antice angula- 

 tim arcuato ad canalem contracto ; labio interno in medio sub- 

 ventricoso, ad basin rostrarum sub-tumido, ad canales rectiusculo. 



Smooth in the centre, which is slightly ventricose, and striated 

 at the ends, which are narrow, and rather straight. At the ante- 

 rior part of the aperture, the outer lip, after widening at the 

 usual place, contracts rather suddenly, and recedes at the canal. 



The pale variety was taken in sandy mud, and brought by Dr. 

 Sibbald from Japan. The beautiful red variety with the white 

 band in the middle is from Sincapore.
