Cornuspira (part) of Authors. 



Test in the early stages planispiral, the coils of fairly uniform 

 height, in the adult the height of the coil greatly increasing and no 

 longer truly coiled but spreading out in a fan shape; interior not 

 divided into chambers; wall calcareous, imperforate, showing distinct 

 lines of growth; aperture in the adult very elongate, on the peripheral 

 margin of the growing edge. 



Recent. Cold water of the North Atlantic.

 Res., 1928, p. 161, pi. 54, figs. 12, 13. 



Test large, very much compressed, the early stages planispiral, the 

 coils of fairly uniform height, in the adult the height of the coil very 

 greatly increasing and no longer truly coiled but spreading out in a 

 fan shape; interior not divided into chambers; wall calcareous, 

 imperforate, showing distinct lines of growth and the whole surface 

 finely striate; aperture in the adult very elongate, slit-lilve, on the 

 peripheral margin of the growing edge. 



Length up to nearly 25 millimeters. 



Most of the records for this species are from the cold waters about 

 the British Isles, but Heron-Allen and Earland found large speci- 

 mens in their material from the Antarctic. Chapman has recorded 

 the species from the Tertiary of Australia, but unless his specimens 

 are very early stages, they do not seem to really belong here. 



Kiaer ^^ refers this to an old manuscript name Cornuspira penero- 

 ploides of M. Sars.
