a type genus, and which is preoccupied by the Globo- 

 truncaninae of Brotzen, 1942), the "new" subfamily 

 Globotruncaninae (which was proposed by Brotzen, 

 1942, and is not new with Hofker), which is comprised 

 of foiu- genera, Thalmanninella Sigal, 1948, Rotalipora 

 Brotzen, 1942, Globotruncana Cushman, 1927, and a new 

 genus, Marginotruncana Hofker. Thalmanninella is 

 here shown to be a synonym of Rotalipora, jwhich be- 

 longs to the family Globorotaliidae, and Marginotrun- 

 cana, as based on the type species selected by Hofker, 

 is a true Globotruncana (see below under the description 

 of that genus), although Hofker also included other 

 unrelated species in his proposed genus, including 

 species of typical Praeglobotruncana, Rotalipora, and 

 Abathomphalus.
