Like the planktonics with which it is associated in these samples, 

 this is a cosmopolitan species in the deeper water of the world's oceans. 

 It is distinguished by its fissured appearance and its smooth surface 

 with translucent wall, through which the coarsely perforate and can- 

 cellated surface of the immature stages are visible. 



The degree of Assuring (widely open or barely fissured) and the 

 shape of the whole test (smoothly spherical, nearly bispherical, or 

 slightly bulging) shows a wide range of variability in the present 

 material.

This species occurs in a few samples, sometimes rather commonly. 

 Orthodox specimens are coiled in a high spire but in many of the 

 present specimens the spire is obscure and the whole test rather ab- 

 normally shaped. The wall is characteristically smooth, thin, and 

 translucent, and in the adult the aperture consists of the sutural pores.

Single specimens were found in Albatross stations H3823, 

 H3919, and H3937, in the Tuamotu Archipelago, at depths of 782, 

 1,494, and 1,688 fathoms respectively. The species appears to be 

 distributed widely but nowhere abundantly. 



Banner and Blow (1960b, pp. 25-26) discuss the distinctions between 

 this species and the closely related species Hastigerinella digitata 

 (Rhumbler) , concluding that the distinctions are of generic importance. 

 Although I regard this conclusion as subject to considerable doubt, 

 solution of this question is not of immediate concern. It is sufficient 

 here to say that the three specimens from the present material fall
