STRUTHIOLARIA. 133 



Section II. ARRHOGES, Gabb, 1868. 

 A. OCCIDENTALTS, Beck. PL 12, fig. 33. 



The longitudinal ribs of the spire, and absence of tuberculated 

 angles on the whorls, as well as the entire but greatly expanded 

 lip, will readily distinguish this species. Length, 2-2-5 inches. 



Labrador, Newfoundland. 



Subfamily Struthiolariinse. 

 Genus STRUTHIOLARIA, Lam., 1812. 



The synonymy of the few species of this New Zealandic genus 

 was very much involved until 1876-7, when the Marchioness 

 Paulucci (Bull. Soc. Mai. Ital., ii, Hi), critically studied them 

 and gave them essentially the nomenclature which follows. 



Section I. STRUTHIOLARIA (s. stricto}. 

 S. PAPULOSA, Martyn. PI. 12, fig. 34. 



Whorls strongly nodose on the angle; yellowish brown, indis- 

 tinctly longitudinally chestnut-striped. Length, 3 inches. 



New Zealand. 



This is Murex stramineus, Gmelin ; S. nodulosa, Lam. ; S. papil- 

 loHa, Gray ; S. cofonarium, Soland. ; S. nodosa, Gray. 



S. VERMIS, Mart. PI. 12, figs. 35, 36. 



Shoulder obtuse, obsoletely nodose, suture somewhat ex- 

 cavated. Length, 1*75 inches. 



New Zealand. 



The synonyms are S. australis, Gmelin ; S. scutulata, Hutton; 

 S. mermts, Sowb. 



Var. CRENULATA, Lam. Fig. 35. 



The sutural channel deeper, the numerous nodules of the 

 shoulder-angle small but more distinct. S. canaliculata, Speng., 

 is a synonym. 



S. GIGAS, Sowb. PI. 12, figs. 37, 38. 



Less sharply angled, the nodules smaller, the suture slightly 

 channeled, the striae alternately larger and smaller, the lip more 

 solidly thickened than in S. papulosa. Very like a gigantic S.
