A HKVISION OF THE A ITS riJAF-IAX TURRID.K HKDLEY. 255 



Tlif slifll of (7in'//.v is cliinucterised by the followiiif^ features: — B'lat 

 indetiuite t'asciole, iiuiicated oiil}^ by the curve of growth lines; a smootli 

 sul)iUate protoooiieh. An insimiation of the outer lip, near tiie base, like 

 that of ,S7/()//aA//s .■ a major sculpture of prominent arched scales on the 

 shoulder, and a minor sculpture of dense, microscopic, waved, spiral striae. 

 The animal was figured by Quoy and Gaimard in the atlas of the zoology 

 of the Astrolabe.*'^ An operculum of I'. nidiinhiiiUs Garrett from Cebn, 

 IMiillipines, is here shown ( PI. .kI v., tig. 51) to have a medio-lateral nucleus. 



The specific identity of the genotype SfrnDihuK livulH.<i was left in 

 doubt by Hanley'''' when he studied the Linnean collection, and it has not 

 been decided since. I therefore wrote to Di'. Nils II. Odhner, of the 

 National Museum of Sweden, inquiring if he could obtain any information 

 on the subject. He kindly replied (21st February, 1918) that he had in 

 turn referred to Professor Wiren, in charge of the museum at Uppsala, 

 where the Linnean types are, who answered : " A specimen labelled by 

 Thunberg as Stronihiis livldnK, Mus. Gust. Ad., is present here, and it may 

 be considered with gi-eat probability to be the same as Linne described in 

 the Mus. Ludovicfe Ulrica?, 1764." This type specimen was submitted to 

 Dr. Odhner, who described it as corresponding in shape, size, and colour 

 to Pleurototiia echinata, as figured by Reeve."*" The identifications of 

 Stromhus by Chemnitz and Solander^s are thus shown to be erroneous. 



Cl.AVUS .ENEUS ^l'. ItiiC. 



(Plate xlv., fig. 46.) 



Shell small, solid, cylindro-fusiform, polished, constricted at^ the 

 sutures. On decollate specimens six whorls remain, divided by linear 

 sutures. Colour amber-brown, with ochraceous reflections. Sculpture: — 

 Ribs prominent, arcuate, each slightly overhanging the one below, seven 

 to a whorl, consecutive on the spire, smaller on the last whorl where they 

 do not reach the base; on the base and snout are six revolving threads. 

 Aperture rather wide, flanked by a tall and thick varix ; edge of lip thin, 

 insinuate at the base ; columella perpendicular and concave ; canal short 

 and wide ; sinus wide and shallow; a prominent callus knob at the lip 

 insertion. Length 11 mm., breadth 4 mm. 



This resembles Clavns fut;co]n'te)tt; Sowerby, but is much smaller, 

 proportionately narrower, with fewer and more prominent ribs. 



Hub. Queensland : — 5 to 8 fathoms, Murray Island (self).
