[Eeceived March 22, 1871.] 

 (Plate XXXIV.) 



Helix alfredi, sp. nov. (Plate XXXIV. figs. 1, la.) 



H. testa imperforata, depresso-globosa, glabra, nitida, polita, nigro- 

 brunnea, duabus fasciis opaco-albis ornata, una ad peripheriam, 

 altera infra suturam ; spira late conica ; anfractibus quinque, 

 lente accrescentibus, planiusculis, ultimo antice deflexo ; apertura 

 semiovali; peristomate albo, simplici, breviter rejUexo ; columella 

 dilatata, appressa. 

 Diam. maj. 0"93, min. 082, alt. 0'85 unc. 

 Hab. Solomon Islands {Coll. Hargraves). 



This will add another to the large number of beautiful species 

 which have recently been obtained from this group of Islands. It 

 is unlike any other species which I have seen ; easily recognized by 

 its black-brown polished appearance, banded by two strongly con- 

 trasting broad white opaque bands. 



I have named this species in honour of Capt. H.R.H. The Duke 

 of Edinburgh, from whom I received during his late visit to this 

 colony some valuable species of shells from his private collection. 



Helix millicent^e, sp. nov. (Plate XXXIV. figs. 2, 2 a.) 



H. testa imperforata, depresso-globosa, tenui, nitida, obsolete cari- 

 nata, undique rugoso-granulata ; spira elevata, pallide castanea, 

 fascia alba ad peripheriam etflammulis opaco-albis undique ornata; 

 anfractibus quinque, parum convexis, ultimo antice deflexo ; aper- 

 tura subangulata, lunato-circulari ; peristomate expanso, albo, 

 breviter reflexo, marginibus conniventibus ; columella dilatata. 

 Diam. maj. 0*98, min. 0-80, alt. 075 unc. 

 Hab. Louisiade Islands {Coll. Cox). 



A rather thin, delicate, handsome species, having the general form 

 of H.fringilla, but being at once distinguished from it by its coarse 

 wrinkled granular surface and by the absence of the tooth-like pro- 

 jection of the peristome near the columella. 



Bulimus hargravesi, sp. nov. (Plate XXXIV. fig. 3.) 

 B. testa perforata, fusiformi- oblong a, tenuicula, Icevi, longitudina- 

 liter subtiliter striata, transversim striis rugato-crassis, obtectis, 

 sub epidermide lutescente alba, macu/is triangularibus olivaceo- 

 fuscis generaliter picta ; spira oblongato-conica, nuda, apice 

 acutiuscula, rosea, granulata ; anfractibus 6, convexis, ultimo f 

 longitudinis csquante ; apertura verticali, elongaio-auriformi, intus 

 albida, nitida, marginibus crassatis, reflexis, albidis, callo non 

 junctis ; margine collumellari dilatato, superne callo adpresso,
