cies under the name Polymorphina complanata d'Orbignj^^, but the 

 two have almost no features in common excepting the alternating 

 chambers. 



Cushman described and figured the microspheric form of the present 

 species from British Columbia. 



To the same form Galloway and Wissler later gave the name 

 Polymorphina elongata, which is considered by them to be the same 

 as Bagg's Polymorphina compressa, but Bagg's P. compressa has 

 depressed sutures and more rounded chambers, the characteristics of 

 Pseudopolymorphina, and is quite different from Galloway and 

 Wissler's P. elongata. Moreover, P. elongata is preoccupied by 

 Fornasini in 1902. 



Polymorphina biserialis Galloway and Wissler, reported from the 

 Pliocene of Timms Point, Calif., is evidently a full-grown specimen 

 of the present species. 



Distribution. — Polymorphina charlottensis is a species limited to the 

 Pacific as far as known. It is only known from the late Tertiary and 

 as a Recent species. We have specimens from the following localities: 



Recent. — Queen Charlotte Sound, British Columbia, 25 fathoms. 

 Albatross D 4825, D 4826, D 4878 off Japan, 84-114 fathoms. 



Pleistocene. — Lomita Quarry, Palos Verdes Hills, California. 



Pliocene. — Timms Point, San Pedro, California. Natsukawa, 

 Province of Echigo, Japan.
