The specimen from Stat. 95 is a worn, broken shell, but quite typical in shape, with two 

 tubercles between the varices. rhose from Stat. 289 are small, with 3 or 1 rows of numerous 

 h of the upper whorls; thej are stil] more characterised by having distinct spines, 

 onlj ted at their foot, instead of the broad wings with short spines, characteristic for the

1 Inly one broken shell, which agrees in every respect with my specimen from Torres- 

 strait. Tryon lias only mentioned it in his register, as a synonym of G. perca, but not in his 

 systematic enumeration. Boog Watson in his " Challenger"-Gastropods, has mentioned it (p. 402) 

 also as a synonym. E. A. Smitii (1. c.) and Brazier have separated it, I think on sufficiënt 

 groufids. Indeed, if one compares the shells, they are very different; with the same number of 

 whorls, the shell is still much smaller, than the var. aculeata of the preceding species, and has 

 the tubercles on the whorls still more numerous, the varices are impressedly striate, not ribbed, 

 with broad interstices, as in G. perca.
