entirely without bands excepting that at the suture. The bands 

 do not extend quite to the outer lip, but stop short about 4 miUims. 

 from the margin. Tbree of the four specimens examined have a 

 shallow concentric depression or furrow around the middle of the 

 base of the body-whorl ; but this is not an essential characteristic, 

 as there is not the slightest trace of it in the fourth shell. 



a. tomasinelliana of Tapparone-Canefri is very like this species 

 in many respects, but is different in form, being higher in propor- 

 tion to the width and v\ith a flatter base. 



Placostylus guppyi. (Plate XL. fig. 6.) 



Testa riinata, elongato-ovata, siiperne acuminata, solidiuscula, 

 riifescens, epidermide fusca, superne plus minus detrita, 

 induta, longitudinaliter rugose striata, interdum in anfractu 

 ultimo obsolete malleata ; anfract. 5-6, celeriter accrescentes, 

 siipremi tres planiusculi vel vLv convexi, penult imus con- 

 vexiusculns, ultimus magis convexxis, magnus, ohlongus, infra 

 suturam ohliquam suhmarginatus, leviter corrugato-plicatus ; 

 apertura inverse auriformis, longit. totius | superans, longe 

 intus pallide rufescens, lahrum versus saturatior ; peristoma 

 incrassatum, leviter expansum, rufescens, marginibus callo 

 tenui albido junctis, columellari in regione umbilici late 

 expanso, in apertura plicam alham validam formante ; 

 apertura tuberculo alba prominente supra iMcam columel- 

 larem armata. 

 Longit. 80 millim., diam. maj. 37 ; apertura intus 40 long a, 



19 lata. 

 Sab. Solomon Islands. 



Mr. Brazier does not know the particular island where this 

 species is found. He possesses only five specimens of it, and of 

 these he has most liberally placed two of the finest in the British 

 Museum. 



The species does not compare closely with any other form. It is 

 rather ventricose, but less so than PI. eddystonensis ; but in other 

 respects it is quite different. The epidermis is of a rich brown 

 colour, here and there striped with a darker tint. The columellar 

 fold and the tubercle above are strongly develojied. 



I have named this interesting species after Dr. H. B. Guppy, 

 who has considerably advanced our knowledge of the fauna of the 

 Solomon Islands. 



Placostylus calus '. (Plate XL. fig. 7.) 



Testa elongata, perforata, superne rufescens, in anfr. ultimo 

 pallidior, epidermide flavo-olivacea tenui induta, incrementi 

 lineis tenuibus striata, sub lente microscopice et irregulariter 

 transversim striata ; anfractus 6, celeriter crescentes, su- 

 premi parum convexi, ultimus elongatus, magnus, ])sroblique 

 descendens, ad sinistram peculiariter injlatus vel gibbws ;
