A REVISION OF THE ACSTRALUN ITKRID.t HKriLKV. 351 



Because its label had been left blank this species was formerly 

 reported as missing from the "Chevert" collection, bat on a second and 

 closer examination a tjpe label was foand concealed in the bottom of the 

 box enclosing the specimen. Br aid of the type thas recovered, and now 

 figai-ed, I can trace this Papuan species along the Queensland coast. 

 Aastfalian specimens are a little larger and slightly different in colour, 

 and as the original description is rather brief, I add a description of the 

 shells from Lady Elliot Island. 



Shell small, glossy, rather solid, subcylindrical, and constricted at 

 the base. Colour white, with two narrow orange-brown zones, the first 

 immediately below the suture and ascending the upper whorls, the second 

 ruuning above the basal furiow and ending on the varix. Sculpture: — 

 The ribs are continuous and perpendicular, set eleven to a whorl, wider 

 than their breadth apart; the spirals are four on the upper whorls, and 

 nine on the last; of these two small coloured threads run close together 

 beneath the suture, and are followed by three thick wide-spaced uncoloured 

 cords on the periphery, then by a coloured cord of equal calibre ; below 

 that is a massive spiral, and lastly two small bead rows set close together 

 on the extremity of the snoat; the meshes on the periphery are rathej- 

 deep, oblong, and translucent. Aperture wide ; varix prominent, and 

 much larger than the ribs; within the outer lip are four small denticules : 

 sinus small; canal short and broad. Length 63 mm., breadth 3 mm. 



Eah. New Guinea : — 4 fathoms, Katow (type, " Chevert"). Qaeens- 

 land: — Lady Elliot Island (Miss Lovell) ; Facing Island, Port Curtis 

 (Kesteven). Western Australia: — Cottesloe (Henn). 



PSEUDODAPHNELLA EETELLAEIA Sp. nOV. 



(Plate Ivi., fig. 189.) 



Clathurella languida Brazier, Proc. Linn. Soc. N.S.W., i., 1876, p. 154 (not 

 Pleurotcmia laugidda Reeve, Conch. Icon., i., 1845, pi. xxix., fig. 257). 



Shell small, lanceolate, subturreted, thin. Colour dull white, with a 

 few brown spots on the shoulder, and the apex brown. Whorls eight, 

 including a protoconch of three and a half whorls. Sculpture harsher on 

 the earlier whorls; radials narrow, almost lamellate, endirjg abruptly at 

 the shoulder and gi-adually on the base, slightly oblique, widely spaced, 

 on the last whorl fourteen and on the penultimate sixteen; these are 

 crossed by spiral threads of smaller gauge, forming long narrow meshes, 

 amounting to sixteen on the last whorl and to six on the penultimate ; 

 fascicle flat,, only incised by crescentic growth lines. Apeiture ovate; 

 ont,er lip forming a small varix, ascending the previous whorl and enclosing 

 a C-shaped sinus ; lip dentate at the margin and tuberculate within ; canal 

 short and wide. Length 6 m.m., breadth 23 mm. 



From P. melaiioxytum'H.eryieT this differs by larger size, more slender 

 form, and by a sculpture composed of threads rather than beads. 



Hob. Queensland : — 15 fathoms. Palm Island (type); 5 to 8 fathoms, 

 Murray Island (self); 20 fathoms, Darnley Island (Brazier).
