NODOSARIA CONSOBRINA D'Orbigny, var. EMACIATA Reuss, 



Plate 13, figs. 3-5. " 



Brady figures under this name an elongate somewhat curved 

 Nodosaria which does not seem so strikingly like Reuss's original 

 figure of Dentalina emaciata^ as do the specimens referred to Denta- 

 lina intermedia by Hantken. Whether the recent specimens are the 

 same as the fossil ones of Europe must be left until a study of the 

 latter can be made. Of the Atlantic Challenger records two occur 

 in the western Atlantic, one off the West Indies, the other off Ber- 

 muda. Flint's specimens of this variety^® were from the northern 

 part of the Gulf of Mexico. I have had the species from stations 

 in the same region, and also, as occurs with many other species, speci- 

 mens from as far north on the southeastern Atlantic coast of the 

 United States as latitude 34°. From these records of the Challenger 

 and Albatross dredgings, therefore, there «eems to be developed a 

 species of the form figured by Brady and Flint and which I have 

 again figured here, which is, so far as the material I have examined 

 shows, confined to the western tropical and subtropical Atlantic. 

 On the eastern side of the Atlantic there are records under this 

 name by Pearcey as rare in the warm area of the Faroe Channel,*" 

 and by Wright from off the southwest of Ireland, rare, at 345 

 fathoms (631 meters).*^ This variety, however, does not seem to 

 be mentioned in the works on the general region of the British 

 Isles in the last 30 years.
