198 Mr. J. C. Melvlll on 



Nearly all the following species have been examined by 

 Mr, Ed«;ar Smith, and to him, Mr. Hugh Fulton, and 

 Commander Shopland I would tender my thanks for kind 

 services rendered. 



Nassa {Hehra) polychroma'^^ sp. n. 

 (PI. XII. fig. 1.) 



N. testa ovato-fusiformi, solidiuscula, vario-picta, nxinc rufo-cinerea, 

 nunc pallidiore, nunc spiraliter ochraceo-cincfca ; anfracfcibus 

 quinque, escluso apicali, paullum gradatulis, apud suturas im- 

 pressis, supernis rufis, nodulo-cinctis, penultimo spiraliter bino 

 nodulorum ordine decorato, nodulis stepius nigro-cseruleis, inter- 

 stitiis rufo-liratis, infra, juxta suturas spiraliter rufo et albo squar- 

 rose tessellato, ultimo aufractu similiter decorato, videlicet, quatuor 

 nodulorum ordinibus, nodulis nitidis, interdum albidis, interdum 

 et ssepius nigro-caeruleis, duobus apud medium ordinibus con- 

 tiguis, interstitiis spiraliter rufo-lii'atis, et juxta basin uni- vel bi- 

 nigro-liratis ; apertura ovata, labro extus incrassato, hie illic rufo- 

 puuctato, intus denticulato ; columella rotundo-excavata, canali 

 brevi. 



Loug. 14, lat. 8 mm. 



A highly coloured but variably painted shell, always 

 roundly nodulous, the nodules as a rule being painted blackish 

 blue, shining ; the prevailing ground-colour is either rufous 

 grey or orange-rufous. In one specimen in the British 

 Museum a beautiful spiral broad ochraceous zone surrounds 

 the last whorl. 



Several examples. 



Mangilia {Glyphostoma) fenestrata, sp. n. 

 (PI. XIJ. fig. 2.) 



M. testa fusiformi, crassiuscula, rugosa, albida ; anfractibus novem, 

 tumidulis, quorum apicali lacteo, vitreo, simplici, caeteris longi- 

 tudinaliter costis regularibus instructis, spiraliter rudi-liratis, 

 interstitiis, praecipue in tribus ultimis anfractibus, ssepe pro- 

 fundis et cavis, ultimo dorsaliter apud peripheriam obscure cal- 

 carea zonula interrupta accincto, ad basin paullulum producto ; 

 apertura augusta, labro incrassato, intus denticulato, sinu con- 

 spicuo, lato, margine columellari versus basin bidenticulato. 



Long. 6, lat, 2 mm. 



Slightly resembling, in the irregular chalky-white dorsal 

 band at the periphery of the last whorl, M. {Glyphostoma) 

 calcicinctay M. & S., from Lifu, but of quite different shape. 

 There are evidently many of this genus to be discovered. 



* TToXv^pw/xa, many-coloured.
