A REVIEW OF VOLUTIDAE 



compressed tubercles; columella with from 

 six to eight plaits, the three posterior 

 very small, the two or three anterior gen- 

 erally thickened. This shell is commonly 

 called the Flag Volute.

Alt. 79, lat. ^0 mm. (Holotype); alt. 76, 

 lat. 55 mm. (Winkworth specimen). 



Hab. Seas between India and Ceylon; 



dredged in 20 fathoms, fine sand, south 

 of Manapad. 



The small apex, longitudinally 

 ribbed young whorls and slight sculpture 

 of the body whorl, agree well with H. inter- 

 puncta Interpuncta. It has, however, none 

 of the typical markings of the latter spe- 

 cies, but dark brown, longitudinal stripes 

 on dark orange ground; it is also more 

 elongated. ( Sowerby 's figure is misleading 

 as to proportions). The columellar folds 

 are slight and six in number. 



Genus ALCITHOE E. and A. Adams I858 



Alcithoe H. and A. Adams, I858, Genera Rec. 

 Moll., vol. 1, p. 164. 



Genotype: "Buccinum arabicum" Martyn, now 

 Alcithoe arabica (Martyn). 



Range: Australasia; South Africa; East 

 Africa; Japan. 



Shell ovately fusiform; spire pro- 

 duced; apex papillary; aperture ovate, 

 wide; inner lip with a spreading callus, 

 outer lip dilated, subreflexed; columella 

 usually with four, more rarely five to 

 seven, oblique plaits. 



Important features include the secondary 

 scaphelloid nucleus, the deep and broad an- 

 terior notch of the aperture, the dilated 



aperture and in the genotype the re flexed 

 aperture .

Alt. 50-65 mm. 



Hab. Southeast to South Africa. 



Apex obtuse; spire moderately ele- 

 vated; suture impressed; whorls angulated, 

 the angle tuberculated; shell contracted 

 anteriorly; three plaits on columella; dark 

 colored spiral interrupted bands continued 

 over labrum and visible inside the lip. A 

 distinguishing character is the dark, choco- 

 late-brown posterior blotch upon the inner 

 wall of the aperture.

Alt. 62.5 mm. 



Hab. Off Port Alfred, and Durban {kO 

 fathoms). South Africa. 



"This is of a different shape from 

 the others, the whorls being strongly 

 shouldered, and wider at the periphery, with 

 fewer and larger tubercles, about eight on 

 the last whorl. The size is 66 x k2 mm., 

 including tubercles, but I have seen larg- 

 er rubbed specimens; some fine spiral 

 lines are just visible." 



Turton further states that this 

 may eventually prove to be a distinct spe- 

 cies.
