Testa turrita, rufo-fusca, fascia albida interrupta et linea 
fusca ornata; spira acuta; anfractus 8, obtuse angulati, 
superne declives, costis circ. 10 lavibus parum elevatis leviter 
obliquis instructi ; ultimus spiram vix zquans, leviter intortus, 
inferne levigatus, ad basim liratus, haud rostratus ; apertura 
latiuscula, intus dilute fusca; columella suboblique arcuata, 
superne tubercula parviuscula instructa ; labrum tenue, sinu 
postico latiusculo. 
Long. ro, diam. 4 millim. 
Hab. Durban. 
Allied to P. Layardi, with a sharper spire; the somewhat 
oblique and distant ribs run to the top of the whorls, and 
become obsolete on the lower half of the body whorl. The 
reddish brown colour of the shell is relieved by an interrupted 
whitish band at the angle, surmounted by a thin dark brown 
line. 
CLATHURELLA VERRUCOSA, Sowerby, nov. sp. (pl. 6, 
fig. 14). Testa parva, breviter ovata, rugosa, fusca, spira 
conica, gradata; anfractus 5, primi 2 leaves, sequentes 
biangulati, liris spiralibus 2, crassis confertis valde nodulosis 
instructi; sutura late canaliculata; anfractus ultimus spiram 
superans, superne angulatus, basin versus leviter attenuatus, 
haud rostratus, undique nodulosus ; apertura latiuscula ; 
labrum vix incrassatum ; sinu postico latiusculo. 
Long. 2.75., diam. 1.50 millim. 
Hab Port Elizabeth. 
This species was erroneously referred by me on page 7 
of “ Marine Shells of South Africa,” as Mangelia clathvata, M. 
de Serres, from which upon further examination I find it to 
be quite distinct.

Mancitia cast, Reeve, Conch. Icon. (Mang.), pl. 7, f. 55: 
Kalk Bay. Tryon (vol. vi., p. 305) proposed the name 
of Daphnella Reeveana for this species, on account of the pre- 
occupation of the name by Hinds in the genus Pleurotoma, 
and considering both to be Daphnelle. It seems to me, how- 
ever, that Reeve’s species is a true Mangilia, while that of 
Hinds is, though somewhat uncertain, probably a Daphneila, 
certainly not a Mangilia,
