 Figure 5. — Spirillina vivipara Ehrenberg var. revertens Rhumbler. 



Challenger Sta. 219A, Admiralty Islands, Pacific. (17 fathoms) 

 Referred by Brady to S. vivipara Ehrenberg, and by Rhumbler (Zool. Jahrb., Vol. 24, 1906, p. 32) to 5. 

 vivipara var. revertens. Galloway (Manual of Foram., 1933, p. 88) raised this variety to specific rank and desig- 

 nated it the type of Mychostomina Berthelin 1881. Cushman (Foram., Class, and Econ. Use, ed. 2, 1933, p. 

 233, and subsequently) placed Mychostomina in the synonymy of Spirillina Ehrenberg 1843. Loeblich and 

 Tappan (personal communication) are presently studying Mychostomina, and this figure of Brady may re- 

 quire revision subsequently.
