NOTES ON MARGINELLA. 



By J. R. LE B. TOMLIN, M.A. 



(Read before the Society, January 12th, 1916). 



Marginella seminula Ball, Bull. Mus. Comp. Zool., Harvard, 

 ix., p. 72 (1881); ibid., xviii., p. 139, pi. 19, f. 2, 

 This name, given to a deep-water species from Yucatan Strait, 

 640 f., is preoccupied by M. semimila Gould, Proc. Bost. Soc. N.H., 

 vol. vii., p. 384 (1861), from False Bay, Cape of Good Hope. I, 

 therefore, rename it Marginella abyssorum. 



Marginella glauca Jousseaume, Guerin's Rev. et Mag. de Zool, 

 iS75» P- 234, pl- 8, f- I. 



Preoccupied by AI. glauca G. Fischer, Mus. Demidoff, torn, iii., 

 p. 172 (1807). 



I think it is very doubtful whether Jousseaume's shell is anything 

 more than a form of M. quinqiieplicata Lam., but, if necessary, the 

 name ^M. loebbeckeana Weinkauff, applied to the same form, is 

 available. 



Jousseaume gives no locality for his shell, but Weinkauff quotes 

 Singapore (Cuming), Ostafrika, Nicobaren, Ceylon (Reeve). It is a 

 common shell at Singapore, where M. qidnqneplicata Lam. is also 

 abundant. 



Marginella ventricosa Hedley, Memoirs of the Australian 

 Museum, iv., pt. 6, p. 369 (1903) — new name for M. ovidxfonnis 

 Tate and May. 



There is already 'Jf. ventricosa G. Fischer and "M. ventricosa 

 Hutton, so I propose to call Tate and May's and Hedley's species 

 M. bticca, and Hutton's fossil species M. fracta. 



The full description ot Fischer's shell is as follows : — " Marginella 

 bossue, bleuatre, ventrue ; la spire tres courte, la columelle a cinq 

 plis, la levre fortement bourrelee, lisse. La patrie est inconnue." 



There can be very little doubt that this applies to M. quinqueplicata 

 Lam. — a name which M. ventricosa Fischer antedates by 15 years.
