FORAMINIFERA OF THE ATIJiNTIC OCEAN. 



159 



Description. — Test subglobular; chambers indistinct; sutures in- 

 distinct, not depressed, surface ornamented with longitudinal costae, 

 frequently broken into short sections; apertural end with a slightly 

 projecting ring about the aperture. 



Length up to about 0.50 mm. 



DiMrihution. — The species is common about the southern portion 

 of the British Isles and more rare in the northern portion. Goes 

 does not record it from the Scandina\'ian region, and it has not oc- 

 curred in the western Atlantic collections I have examined. The 

 only records outside the British Isles seem to be that of Sidebottom 

 who had specimens referable to this species from off the Island of 

 Delos in the Mediterranean, and of Williamson, who quotes " Tene- 

 dos (Levant)." 



The distribution of a striking species of this sort seems to show 

 that the fauna of the southern coast at least of the British Isles is 

 related to the Mediterranean, rather than to the western Atlantic. 



I have had excellent material from Europe and if its distribution 

 included the western Atlantic, it would have surely been seen in the 

 Albatross collections. 



Folymorpliina myristiformis — material examined. 



POLYMORPHINA ELEGANTISSIMA Parker and Jones. 



The only recent Atlantic records for this species are those given 

 by Egger from western Africa and off the Cape Verde Islands. It is 

 a species common in shallow water of the Indo-Pacific and has not 

 occurred so far as I have seen where it might be most probably 

 looked for, that is, in the tropical portion of the western Atlantic. 

 It occurs as a fossil in the Tertiary of the Coastal Plain of thvi 

 United States, and, according to Heron-Allen and Earland, fossil 

 in England.
