SIPHONALTA. 135 



S. TUBEROSA, Reeve. PI. 54, fig. 354. 



Chestnut-brown, white on the principal spiral ribs and nodules ; 



aperture bluish white. Length, 8 inches. 



Japan. 

 S. MAXIMA, Tryon. PI. 54, fig. 355. 



White, sprinkled and blotched with light chestnut-brown on 

 the spiral ribs ; a broad, l)rown band between the tubercles on 

 the shoulder of the whorls; aperture white. Length, 7*5 inch. 



Tasmania. 



This shell was sent to the Philadelphia Academy by Mr. G. B. 

 Sowerb}', under the name of Siphonalia Taamaniensis, Arigas, 

 and he has since figured a somewhat similar form in his " Thesau- 

 rus" as that species ; TasmanienHifi is, however, a very different 

 species, as will be seen by my copy of the original figure. The 

 present species may possibly he the subject of one of the unil- 

 lustrated diagnoses which I have considered it useless to attempt 

 to identify. 



S. DiLATATA, Quoy. PI. 54, figs. 356-359. 



Pale yellowish brown, the revolving ridges deep chestnut; 

 interior white. Length, 2*5-5 inches. 



New Zealand ; Japan, A. Adams. 



F. aduslus, Phil. (fig. 359) is a synonym. 



Reeve and Hutton both suspect this to run into the non- 

 shouldered F. Mandarinus, Duclos (= Zelandicus, Quoy); if this 

 be so, all the species of Siphonalia. might as well be given up at 

 once. Mandarinus I have referred to the group AaMrofasus. 



S. Cassidari^formis, Reeve. PI. 55, figs. 364-309. 



Reddish orange variously banded and tinged with chocolate 

 and white; apei'ture white or orange. Length, 30-55 mill. 



Japan. 



Quite characteristic in its general appearance, although very 

 variable in coloring. Proliably several of Mr. Arthur Adams' 

 unfigured species are synonymous with this ; Lischke thus iden- 

 tifies two of them, S. ornata and S. conspersa. 



S. Tasmaniensis, Ad. and Angas. PI. 54, fig. 360. 



Yellowish orange more or less fasciated with red (three bands 

 on the last whorl), yellowisli white within. Length, 60 mill. 



S. Australia and Tasmania.
