Description. — Test fusiform ; chambers several, inflated, with deep 

 sutures; wall ornamented with elongate, coarse costae, usually not 

 broken on the individual chambers ; aperture radiate, produced. 



Length not exceeding 0.75 mm. 



Distribution. — The only specimens I have had of this species from 

 the Atlantic have been from the Tortugas region. It is recorded 

 by Earland from Bognor, Sussex, England, a single specimen, and 

 by Heron-Allen and Earland from shore sands of Selsey Bill, Sus- 

 sex, England. Most of the records for the species are from the 

 Indo-Pacific. I have found fossil specimens which seem to belong 

 to this species from the Miocene and Oligocene of the Coastal Plain 

 region of the southeastern United States. 



Subfamily 4. Uvigerininae. 



Test composed of several chambers, typically spirally arranged, 

 especially in the earlier portion, later chambers often becoming 

 loosely arranged, or even uniserial; wall smooth or variously orna- 

 mented; aperture typically consisting of a neck with a definite 

 phialine lip. 



In Uvigerina the spirally arranged chambers are typical, old age 

 characters appearing in the loss of ornamentation or in the tendency 

 to become loosely spiral as in U. interrupta. In Siphogenerina the 

 early chambers are spiral or biserial, especially well-developed in 

 the micospheric form, and the later development is uniserial.

 Description. — Test elongate, spiral, consisting of numerous cham- 

 bers, usually arranged triserially, occasionally in later growth with 

 fewer than three chambers in each volution; wall calcareous, per- 

 forate, hyaline, smooth or ornamented with spines or costae or mod- 

 ifications of them; aperture w^th usually a tubular neck at the end 

 of which is a phialine lip. 



The genus Uvigerina and its related genus Siphogenerina form 

 a very distinctive group. The triserial arrangement of tlie chambers
