Turbo jourdani, Kiener. PI. xviii., f. 32, 33. 



This very rare shell was named and described by Kiener 

 in 1839 in the Rev. Zool. Soc. Cuvier, p. 324, and figured 

 in the Mag. de Zool. de Guerin, 1840, Moll., pi. ix. To 

 neither of these works have we access. 



In 1843 Deshayes, in his edition of Lamarck's Anim. s. 

 Vert., vol. ix., p. 224, says it belonged to the collection of 

 Mons. Jourdan, after whom it was named. 



In 1846 Philippi, in the Conch. Cab., ed. ii.. Band ii., 

 Abt. ii. and iii., p. 56, pi. xiii., f. 4, gives a description 

 and figure, with the remark that he had never seen the 

 species. 



In 1848 Reeve, in Conch. Icon., Sp. 41, pi. xiii., writes: 

 "Of this species there are two examples in the British 

 Museum." 



In 1873 Fischer, in Coq. Viv., Genus Turbo, p. 11, pi. 

 xviii., gives a description and an excellent illustration of the 

 smooth form. 



In 1887 G. B. Sowerby, in the Thes. Conch., vol. v., p. 

 192, Sp. 8, pi. vi., f. 62, figures the form, which is validly 

 spirally ribbed in the spire-whorls and obsoletely in the body- 

 whorl. 



The rarity of the shell is evident from the fact that all 

 the above references but two are to the single shell belong- 

 ing to M. Jourdan. Its habitat was the very indefinite one 

 of "Australia" and "New Holland." 



In 1888 Mr. M. M. Maughan found an immature ex- 

 ample on the beach of Moonta Bay, in Spenoer Gulf. It was 

 identified by Prof. Tate, who held the opinion very strongly 

 that it had been transported thither in ballast. Mr. 

 Maughan saw no ballast about the beach, nor did he at any 

 time gather any foreign shells there, although he did much 

 collecting in the Bay. But no second specimen was ever 

 taken. 



In July, 1888, Mr. T. C. Watson, of Streaky Bay, South 

 Australia, gave Mr. W. T. Bednall three specimens, the
