As pointed out by Thomson (1913, p. 25), Hutton illegally introduced 
S. spinosa (1886) as being more appropriate for his S. tuberculata (1813). 
hus S. spinosa Hutton (1886) is an absolute synonym of 5. tuberculata 
Hutton (1873). But in the same year (1886 
Hector published a figure labelled “ 5. spinosa.” 
No locality is given, but the drawing (text-

the year of issue, but as the Indian and (After Hector’s figure.) 
Colonial Exhibition, for which it was prepared, 
commenced in May it is safe to assume that the publication of the 
catalogue was earlier in the year than that of the Transactions. л 
uter's usage of S. tuberculata for the Broken River species is correct ; 
but he made a serious mistake in connection with the type of S. spinosa. 
Hutton (1873) listed S. tuberculata var. B, giving the localities “ Palliser 
former has a second row of prominent tubercles. A comparison of the 
figures here published will show the difference at once. Struthiolaria spinosa 
must be based upon the shell that Hector figured—i.e., the White Rock 
River species ; while a new name must be applied to the Waikari one.
