Hah^ New Caledonia. 



Although the smallest of Cones this little shell seems 

 sufficiently ciiaracteristie to have a name. Its colour is 

 brightish orange, neatly ornamented at intervals with narrow 

 brown lines, while the surface of the body-whorl is closely 

 spirally grooved throughout. It may be that this and the 

 following are the young of some larger species, but at present 

 I am quite unable to connect them with any known forms. 



Conus vividiis, sp. n. (PI. XIX. fig. 8.) 



Testa minuta, vivide violacea, ad angulum zona angusta albida 

 cingulata, ubique spiraliter sulcata, supra angulum planulata, 

 infra angulum levissime couvexa, basim versus attenuata ; apice 

 prominens crassa, saturate purpurea. 



Long. 5, diam. 2| mm. 



Hab. New Caledonia. 



This brightly coloured little shell, like the last, is closely 

 spirally grooved ; it is characterized by an almost flat top, 

 from which a prominent dark purple apex projects. I have 

 seen about a dozen specimens of this species, presenting 

 scarcely any variation in size, shape, or colour. 



Mitra multisulcata, sp. n. (PI. XIX. fig. 3.) 



Testa elongato-fusiformis, fulvo-fusca ; spira elata, acuta ; an- 

 fractus 7, vix convexi, ubique spiraliter sulcati ; sulcis nuraerosis, 

 profuudiusculis, leviter crenulatis, aequaliter latis ; sutura an- 

 gusta canaliculata ; anfractus ultimus | lougitudinis testfe 

 sequans, leviter convexus, basim versus leviter attenuatus. 

 Apertura elongata, iutus alba; columella tenuiter albo-callosa, 

 quadriplicata, plieis validis, leviter obliquis ; labrum crassius- 

 culum vaHde crenulatum. 



Long. 31, diam. 12 mm. 



Hah. New Caledonia. 



The only species with which I can compare this is M. riip- 

 pelli (Reeve), than which it is larger, more fusiform, and the 

 spiral grooves are more numerous. I have before me several 

 specimens of the new species, presenting scarcely any varia- 

 tion, and all having about the same number of grooves. 



Mitra glabriUrata, sp. n. (PI. XIX. fig. 5.) 



Testa parva, elongato-fusiformis, angusta, fusco-nitens ; anfractus 7, 

 primi laeves, rotundati, deinde reetiusculi, longitudinaliter costati ; 

 costis numerosis, laeves ; sutura impressa ; anfractus ultimus | 

 longitudinis testae aMjuans, costis partim evanidis. Apertura
