D. atkinsonii is the common shell, and it seems impos- 

 sible, satisfactorily, to separate our specimens from cremtlaris 

 (Lam.), which has also been described as from Bombay. 

 Young specimens are brownish with purple tinge, and differ 

 a good deal from the massive appearance of the old shell. 

 We should also not be surprised to find out that crassa (Smith) 

 will turn out to be but another form of this species. 8. aviicta 

 seems very common on the coast to the north of Bombay. 



S.fulminata is a beautiful shell when in perfect condi- 

 tion. Lives in deep water, and occurs in Bombay Harbour 

 in mud. 



Of the Mangilicz fortistriata, decipiens, ^SiA foraminata 

 occur most frequently. Tincta is a beautiful little shell, 

 easily known by the brown band at the suture. 



The Nevill types being in the Calcutta Museum, it has 

 been difficult to feel certain of the naming ot some of our 

 specimens. 



Fam. CANCELLARIIDyE. 



Cancellaria (Lam.). 



C. (Trigonostoma) scalarina (Lam.). 



C. „ costifera (Sowb.). 



This family is not at all common, and it may be that 

 these two species are but forms of one. All were found 

 in one locality, washed up by heavy seas. They are 

 deep water shells.
