There are numerous records for this species, especially in the east- 

 ern Atlantic, but in the Albatross collections I have had no material 

 which I can refer to this species. 



POLYMORPHINA ANGUSTA Eyffer.

The only record for this species from the western Atlantic is that 

 given bj^ Woodward from Mnemsha Biglit, Marthas Vineyard. This, 

 from a study of my own collection, is probably Polymorphina lactea 

 (Walker and Jacob), var. novangliae Cushman. 



Heron-Allen and Earland record a single specimen, apparently 

 recent, from shore sands of Selsey Bill, Sussex. There are numerous 

 other records from Australia and the Indo-Pacific.

DescHption. — Test much compressed, generally rounded in outline, 

 about as broad as long ; chambers few, very slightly inflated ; sutures 

 distinct, very slightly depressed; wall smooth; aperture very slightly 

 produced, radiate. 



Length up to 0.50 mm. 



Disti'ibution. — I have placed under this species two specimens of 

 a flattened form which is somewhat similar to the figure given by 

 D'Orbigny in 1846. They are from two stations, one in the Gulf of 

 Mexico, the other off the coast of South America. The figured 

 specimen (plate 40, fig. 3) shows a fistulose form from the Gulf of 

 Mexico. There are numerous other records for the species, as the 

 above references show.
