The shuttle Volute. Shell elongately ovate, atten- 

 uated at each end, spii'e acuminated, papillary, 

 rather sharp at the apex, whorls smooth, shining, 

 convex, slanting round the upper part, columella 

 obliquely four-plaited, aperture rather narrow, lip 

 but slightly thickened ; livid fulvous white, encircled 

 with two obscm-e light-brown bands, and indistinctly 

 longitudinally marked with fine waved lines, sutures 

 of the spire partially stained and dotted with chestnut- 

 brown.

 Voluta pallida. Gray. 



Hab. Mouth of the Swan River, Australia. 



I cannot doubt of this being the Voluta volm, con- 

 founded by Lamarck with the Voluta Jlavicans under the 

 name V. volvacea. The V. Tnnieri of Mi-. Gray, repre- 

 sented by IVIi-. Sowerby as a variety of this species, is 

 certainly distinct, and the shell figured by Mr. Sowerby 

 (Thes. Couch, pi. 53. fig. 94) as another variety, is the type 

 of my V. reticulata. The very delicate waved lines of 

 colour wliich characterize the V. volm ai-e more frequently 

 absent or obliterated than present, and ai-e rarely moi-e 

 (Ustinctly mai-ked than in the accompanying figiu-e. 



Species 25. (Mus. Dennison.)

 The reticulated Volute. SheD elongately ovate, spire 

 somewhat acuminated, papillary, rather sharp at the 

 apex, whorls smooth, convex, slanting round the 

 upper part, columella four-plaited; fulvous white, 



staiued and darkly streaked at the sutures, and finely 

 triangularly retieidated throughout with fulvous 

 chestnut, the net-work being darker and confused at 

 the base and in two bands, colimiella and interior of 

 the apertm-e fulvous chestnut. 

 Reeve, Pro. Zool. Soc. 1843, p. 144. 

 Hab. North of Swan River Settlement, Australia; Dring. 

 This fine shell, from the collection of Mr. Dennison, is 

 the true type of the species under consideration, described 

 by me on its an-ival in the Beagle in 1843. Another 

 specimen, equal in size and not much inferior in colour, is 

 in the collection of Mi-. Norris, and a third, of smaller size 

 but richly coloured, in the Cumingian collection, figured 

 inadvertently by Mr. Sowerby as a variety of the preceding 

 species. Besides these, there are three specimens of a very 

 distinct variety, if not specifically distinct, in the collections 

 of Sir. Metcalfe, Mr. Gubba, and the British Museum, in 

 which the shell is more ventricose and the net-work of 

 rather a difl'erent character, figured by Mj-. Sowerby (Thes. 

 Conch, pi. 49. f. 47, 48) as V. reticulata true. The dark 

 marks along the sutui-es are also somewhat different. The 

 specimens are very much worn, but they present a pecu- 

 liarity of character which may prove to be of some specific 

 importance. 



Sjiecies 26. (ilus. Cuming.) 



Voluta undulata. Vol. testa elongato-ovatd, crassd, 

 basi subcontortd, spird breviusculd, S7ibacuminaid, an- 

 fractiius leevibiis, superne declivibus, deinde tumidius- 

 culis, colmnelld quadriplicatd ; ferrugineo-albidd vel 

 eburned, lineis casta)ieis Jlexuosis conspicue longitn- 

 dinaliter pictd, colmnelld et aperturrr fauce vivide riifo- 

 auranliis. 



The waved Volute. Shell elongately ovate, thick, 

 slightly twisted at the base, spii-e rather short, some- 

 what acuminated, whorls smooth, slanting round the 

 upper part, then a little swollen, columella four- 

 plaited ; rusty or ivory white, conspicuously longitu- 

 dinally painted with flexuous chestnut lines, columella 

 and interior of the aperture bright red-orauge. 



Lamarck, Anim. sans vert. (Deshayes' edit.) vol. x. 

 p. 401. 



Ilab. Tasmania, and Gipp's Land, South Australia. 



This well-known species varies from a polished-i\ory 



white to a rusty red-brown, but is always chai-acterized bv 



the same design of longitudinal waved lines. 



November, 1849.
