MARGINELLA, species? 



A young specimen, Cat. No. 250326, U.S.N.M., from Port Alfred 

 (Coll. No. 1199), of a more or less uniform pearl gray ground color, 

 with an interrupted band of spots on the middle and spotting on the 

 spire, which we are unable to arrange with any of the described forms.

Cat. No. 186726, U.S.N .M., two from Port Alfred (Coll. No. 85). 



MARGINELLA ZONATA Kiener. 



There are three color phases in the material before us, typical 

 zonata with the broad belt of brownish orange of which Cat. No. 

 186715, U.S.N.M., contains three specimens from Port Alfred (Coll. 

 No. 74) and Cat. No. 227710, eight specimens from the same locality 

 (Coll. No. 805). We have also seen 92 specimens of this in Colonel 

 Turton's collection (Coll. No. 1600), from the same place. Then, 

 a form in which the markings are reversed — namely, a white belt 

 with the tip and base brownish orange. Of this, Cat. No. 186715a, 

 U.S.N.M., contains three specimens from Port Alfred (Coll. No. 74) 

 and Cat. No. 227712, eight specimens from the same locality (Coll. 

 No. 807). Of this, I have also seen 66 specimens in Colonel Turton's 

 collection (Coll. No. 1602). Lastly, a phase in which the brownish 

 orange is restricted to a very narrow subsutural band. Of this, Cat. 

 No. 186724, U.S.N.M., contains three specimens from Port Alfred 

 (Coll. No. 83), and Cat. No. 227711, U.S.N.M., eight specimens from 

 the same source (Coll. No. 806). Ninety-three more were examined 

 Colonel Turton's collection from the same place (Coll. No. 1601).
