SOWERBY : VOLTJTA BEDNALLI. 49 



Ampxtllaria granulosa, n.sp. PI. IV. Fig. 24. 



Testa globosa, solidiuscula, anguste rimata, nigro-fusca, undique 

 granulis conspicuis niimerosissimis sculpta ; spira curta ; anfractus 

 convexi, rotundati ; area suturali planato concava ; anfractus ultimus 

 ventricosus, humerosus ; apertura lata, fauce interruptim fasciata ; 

 peristoma acutum, rufo-aurantio stiff uso. Long. 63, maj. diam. 

 55 mm. Apertura longa 42, lata 25 mm. Hah. — Cayenne (Capt. 

 Eudel). 



In form and dimensions this species resembles A. glohosa, Swains., 

 but with the umbilicus almost closed. The curious granulation of the 

 surface is such as I have not observed in any other species of the genus. 



NOTE ON VOLUTA BEDNALLI, BRAZIER. 



By G. B. SowERBY, F.L.S., etc. 



Read January Vlth, 1894. 



In 1879 Mr. John Brazier described a very remarkable and beautiful 

 Volute, which he named after the owner, V. BednalU} It was taken 

 oil Port Darwin, JN^orth-east Australia. Subsequently Mr. G. F. Angus, 

 seemingly by an oversight, described it on his own accoimt, adopting, 

 however, the name given by Brazier.^ This beautiful and highly valued 

 shell has until last year remained unique in Mr. Bednall's collection. 

 Though much sought for in the locality where it was found, no second 

 specimen had been obtained. A fully developed specimen, in perfect 

 condition, has, however, recently come into my possession, obtained 

 by a Torres Straits pearl-diver. This shows Mr. Bednall's specimen to 

 be immature, and renders a supplementary description of the species 

 desirable. 



The shell is massive and heavy, of clear cream colour, conspicuously 

 painted with longitudinal somewhat irregular arched and angular 

 flames, and four exceedingly regular transverse narrow bands of very 

 dark reddish brown ; the longitudinal striae are very clear, imparting 

 a beautiful silky gloss to the surface of the shell ; the apex is obtixse, 

 but not worn, the third whorl being neatly and sharply plicated. 

 The interior of the mouth is smooth and shining, of the same colour 

 as the body of the shell ; the four plicae on the columella are promi- 

 nent and rather thick ; the lip is covered with a thick shining enamel 

 overlapping and forming a distinct margin to the body whorl. Length 

 100, greatest width 50 mm.
