Enuerina pacifica Cushman, U. S. Nat. Mus. Bull. 71, pt. 6, p. 64, pi. 21, fig. 2, 

 1917. 



Test in the early stages quinqueloculine, with strongly angled 

 chambers, in the adult with the chambers somewhat more inflated 

 but carinate and irregularly coiled, more than two making up a coil ; 

 sutures fairly distinct in the early portion but not depressed, in the 

 adult much more depressed ; wall smooth, matte ; aperture somewhat 

 projecting with a slightly convex sieve plate, with numerous irregu- 

 larly arranged pores. Length, 0.7 mm. 



The types of this species are from off the Hawaiian Islands in 

 shallow water ranging from 21 to 33 fathoms where it is common. 

 In our material specimens occurred at Guam Anchorage, Ladrone 

 Islands, 21 fathoms, and Mokaujar Anchorage, Fiji Islands.

Test much compressed, the very earliest ones milioline, later ones 

 becoming spiroloculine, and finally, in the last-formed coil, more 

 than two chambers appear, usually three making up a complete coil ; 

 wall very finely striate-reticulate ; periphery rounded or subcarinate ; 

 aperture a sieve plate the entire height of the chamber, curved, with 

 numerous pores. Diameter, 1 mm. ; thickness, 0.15 mm. 



This is a widely distributed species in the Indo-Pacific. There is 

 a very considerable degree of variation shown by the specimens 

 we have. In the early stages the chambers are in a compact mass of
