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.
MARGINELLA MUNDA Smith.
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).
