neck with a phialine lip; surface, bristly-spiny. Length, about 0.6 

 inm. (-^ inch). 

 Locality. Off the Brazil coast (station 2760), 1,019 fathoms. 



Subfamily 



Test irregular, branching. 



Genus RAMULINA. 



Test branching, composed of pyriforin chambers connected by long 

 stoloniferous tubes. 



RAMULINA GLOBULIFERA Brady. 

 (Plate 68, fig. 6.) 



Segments few, subglobular, united by long stoloniferous tubes, and 

 each segment provided with numerous radiating tubulures; walls 

 hyaline; surface bristly with sparsely set fine and short spines. 



Locality. Gulf of Mexico (station 2377,) 210 fathoms. 



RAMULINA PROTEIFORMIS, new species. 

 (Plate 68, fig. 7.) 



Test calcareous, extremely thin and fragile, very finely perforated; 

 surface smooth ; in form very irregular and variable, sometimes branch- 

 ing, sometimes with more or less numerous short digital processes, 

 imperfectly segmented, the segments inflated into a great variety of 

 shapes. The figures show only a few of the myriad forms assumed by 

 this delicate foraminifer.

Test coarsely perforate ; trochoid, rotaliforin, or symmetrically piano- 

 spiral. 



GLOBIGERINA BULLOIDES d'Orbigny. 

 (Plate 69, fig. 2.) 



Subglobular, the adult shell composed of about seven nearly spherical 

 segments, arranged spirally so that all are visible on the upper side, 

 and three or four on the lower side; aperture of each chamber opens 

 into a common umbilical vestibule; surface more or less rough; walls 

 hyaline, finely and distinctly perforated. Diameter, 0.6 mm. (- 4 \ inch) 

 or less.
