pany the Wentletrap are drawn from specimens lately im- 

 ported from New South Wales. Nos. i and 2 are of the 

 Conus genus, and resemble the larger kind in their form ; 

 No. 3 is evidently of the Trochus kind ; No. 4, Pyrula, re- 

 sembling a little pear. They are given to show the variety of 

 their patterns and form, and are hitherto unnamed by any 

 conchologist." 



Plate XXX. is a nice figure of Voluta pacifica, of which it is 

 written that it was discovered " by that accurate investigator 

 of nature, Dr. Solander, in one of the small islands near New 

 Zealand, when employed upon a voyage of discovery with that 

 illustrious circumnavigator, Captain Cooke." 



Plate XXV. contains two beautiful figures of shells, Triplex 

 flavicunda, from Botany Bay and New Zealand, and Triplex 

 rubicunda, from Ceylon. These were both figured under the 

 same names, but not such good figures, in the " Concho logy " 

 (pi. vi., pp. 2 and 4), concerning which Hedley wrote : — 

 " Triplex flavicunda, Perry, and T. rubicunda, Perry, are 

 marked by Deshayes (An. s. Vert., ix., p. 574) as synonyms 

 of Murex adustus, Lam. (1822). Over all these names Purpura 

 scabra, Martyn (Univ. Conch. (1789), pi. 113) has precedence. 

 While agreeing that Triplex flavicunda, Perry = Purpura 

 scabra, Martyn, we would point out that Triplex rubicunda, 

 Perry, seems to differ, and is identical with the shell named 

 Murex rubiginosus by Reeve (Proc. Zool. Soc. Lond., 1845, p. 86), 

 over which it has priority. We have examined Reeve's type. 



Perry notes that Murex ramosus, Linne, should be called 

 Triplex ramosus, as it is not referable to Murex as he restricts it. 



Plate XXIX., named Conus particolor, is a good figure of a 

 specimen of Conus aulicus, Linne. This was omitted from the 

 " Conchology," so has hitherto been unrecorded. 



Plate XLIII. shows Perry's Bidimus phasianus, which 

 becomes a synonym of Phasianella australis, Gmelin. 



Plate XLVII. is a beautiful figure of the shell later named 

 Murex tenuispina by Lamarck. It was re-figured in the 

 " Conchology," pi. xlv., fig. 3, and there re-named Aranea 

 Iriremis. This name has been accepted in lieu of M. tenuispina, 

 Lamarck, by Hedley, but another alteration seems necessary, 

 as on this plate, which has priority, the name chosen is Aranea 

 gracilis. 



Plate LII. is named by Perry Strombus solitaris, which name 

 becomes a synonym of Strombus gallus, Linne. 



Plate LIV. is of a magnificent species of Murex, measuring 

 184 mm. in length, and which is named Aranea conspicua 

 This is a much better figure than the one under the same name 

 in the " Conchology " (pi. xlvi., fig. 3), and, though of such grand 

 dimensions, we have been unable to identify it.
