ART. 25 FORAMINIFERA CUSHMAN AND KELLETT 15 



Glohigerinella aequilateralis Cushman, Bull. Scripps Inst it. Occanograijhy, Tech. 

 Sep., vol. 1, 1927, p. 174. 



Test composed of numerous inflated chambers, trochoid in the 

 young, later in a bilaterally symmetrical, planispiral coil; chambers 

 increasing rapidly in size as added, usually five or six visible in side 

 view; sutures much depressed; wall reticulate; aperture, a large 

 arched opening at the base of the chamber. 



The only specimen is from off Eten, Peru. Like the specimen 

 noted from farther north along the coast, the coil is much less open 

 than is usual in specimens from the Tropical Atlantic.

Anomalina schmitti Cushman and Wickenden, Proc. U. S. Nat. Mus., vol. 75, 

 1929, p. 14, pi. 6, figs. 5 a-c. 



Test with the dorsal side flattened, ventral side, especially in the 

 central portion forming a fairly high spire, last-formed coil evolute 

 on both sides, periphery smooth, keeled, especially in the earlier por- 

 tion; chambers eleven to twelve in the last-formed coil in the adult, 

 not inflated ; sutures distinct, especially between the last few chambers, 

 very slightly depressed, slightly limbate on the dorsal side, gently 

 curved; wall coarsely perforate, especially on the dorsal side; aper- 

 ture low, broad, at the peripheral margin. 



Length, 0.45 mm.; breadth, 0.35 mm.; thickness, 0.20 mm. 



This species has been recently described from Juan Fernandez. 

 It is interesting to record several specimens from Corral, Chile, 

 although it did not occur at any of the other stations. The high 

 spire is a striking character although it is somewhat variable.
