vexus, fascia alba supra et infra medium ornatus, infra medium valde 
contractus, in cauda brevi desinens, spiraliter liratus ; columella quinque- 
plicata; apertura intus albida ; labrum crassiusculum, lseve, nigro-fusco

Sab. Island of Formosa. 
A species belonging to the “ Turricala ” section, somewhat 
resembling M. caffra, but with the whorls more rounded and the 
body-whorl much shorter in proportion to the spire, rounded in 
the middle and contracted at the base. Three specimens from 
the Island of Formosa, all similarly marked, and differiug but 
little in form.

Sab. Mauritius (V. de Robillard). 
A very pretty little species, with a prolonged recurved canal. 
The longitudinal ribs are neatly tubercled at the suture, the 
interstices transversely grooved, and the turreted spire produced 
and attenuated towards the apex. The brown blotches are for 
the most part arranged in two zones above and below the middle 
of the body-whorl. 
Mitea Smithi, sp. nov. (PI. XXY. fig. 6.) 
Testa elongato-fusiformis, albida, fulvo fuscoque sparsim fasciata et 
maculata ; spira acutissima, mucronata, subgradata ; anfractus 1 1 , con- 
vexiusculi, longitudinaliter costellati ; eostellis numerosissimis, angustis, 
confei’tis, rotundatis, lsevigatis, juxta suturam tuberculatis, insterstitiis baud 
striatis ; anfractus ultimus spiram sequans, supra et infra fascia pallide fulva 
fusco maculata picta, zona media albida, infra medium attenuatus, 
spiraliter suleatus et grauulatus, in cauda recurvata desinens ; columella 
leviter sinuosa, triplicata, plicis crassiusculis ; apertura longa, angusta.
