from the angle, and just below the middle of the body-whorl 

 an interrupted belt of quaintly formed white markings ; these 

 show very prominently against the general plain brown 

 colour of the shell. 



I have only seen a single specimen of this species. 



Chrysodomus acuttspiratus, sp. n. (PI. III. fig. 8.) 



Testa ovato-acuminata, luteo-albida, pallide fusco-balteata, ubique 

 spiraliter lirata, liris angustis, confertis, liris fortioribus majis 

 distantibus interveniens ; spira elata acuta, apice papillaris ; 

 anfractus 9, primi 2 laeves, leviter obliqui, sequentes4, angulatim 

 convexi, longitudinaliter nodoso-plicati, deinde regulariter con- 

 vexi ; anfractus ultimus spiram superans, ventricosus infra 

 medium valde contractus, breviter contorto rostratus ; apertura 

 ovata, intus lsevis, fusco-tincta ; peristoma tenue, arcuatum ; 

 columella arcuata, infra medium complicate, sinistrorsum re- 

 flexa ; canalis brevis, leviter reflexus. 



Long. 29, maj. diam. 13 mm. 



Hab. Iyo, Inland Sea, Japan. 



This shell is remarkable for its long acute spire, the spiral, 

 close, fine lirae, with stronger ones at regular intervals, and 

 the rough plica? on the upper whorls. 



Mesalia ex'ilis, sp. n. (PI. III. fig. 9.) 



Testa elongato-turrita, albida, maculis parvis pallide lutescente con- 

 spersa, ubique spiraliter tenuiter lirata. ; spira proelonga, acuta ; 

 anfractus 14, leviter convexi, oblique anguste plicati, plicis 

 granulosis ; sutura anguste canaliculata ; anfractus ultimus \ 

 longitudinis testa3 sequans, convexus, plicis obliquis evanidis ; 

 apertura semilunata ; peristoma tenue ; columella sinistrorsum 

 reflexa ; basis baud canaliculata, sinu latiusculo emargiuato. 



Long. 47, maj. diam. 13| mm. 



Ilab. West Australia. 



The actual generic position of this remarkable shell is 

 uncertain, but I place it provisionally in Mesalia on account 

 of the characteristic basal sinus. 



Mitra marcice, sp. n. (PI. III. fig. 10.) 



Testa ovato-fusiformis, albida, liueis lacteis, vivide fusco interrnptis 

 ornate ; spira mediocriter elata, acuta ; anfractus 8, convexi, 

 longitudinaliter ubique plicate, supra pallide luteo tincti, linea 

 fusca luteo interrupta ornati ; anfractus ultimus | longitudinis 

 testae sequans, convexiusculus, infra leviter attenuates, ad medium, 

 supra, et infra hilariter lineatus ; apertura oblonga, intus fusco 

 fasciate ; columella triplicate. 



Long. 16, maj. diam. 6 mm.
