REMARKS ON THE OAMARU DIATOM PAPERS. 391 



of Bicldulphia and Odontella by Herr Grunow, this would, in 

 his opinion, belong to tne latter. 



Biddulphia ? fossa, Gr. and St. Appears to be Anaulus. 



Syndetoneis amplectans (Gr. and St.), Gran. (Hemiaulus 

 amplectans, Gr. and St.) Not Hemiaulus. 



Coscinodiscus spiniferus, Gr. and St., in Uteris, instead of 

 C. elegans, var. spinifera, Gr. and St., olim. Herr Grunow 

 thinks it is more nearly related to Cestodiscus pulcJiellus than to 

 Coscinodiscus elegans. 



Stictodiscus nitidus, Gr. and St., in Uteris, instead of St. calif or- 

 nicus, var. nitida, Gr. and St. 



Actinoptychus (glabratus var.) elegayitulus, Gr. and St. Is at 

 any rate a distinct species. 



A. tener, Gr. and St., in Uteris, instead of A. pulchellus, var. 

 tenera, Gr. and St.
