previously classifying it with Amphistegina. However that may be, 
there is a considerable amount of variation among these forms which 
in the fossil state would be sufficient to cause their separation into 
several species or at least important varieties of the typical form. 
This matter can not be properly entered into here, but we have pur- 
posely kept Vummutlites radiata separate from Nummulites cumingi, 
notwithstanding that it is considered synonymous by Prof. H. B. 
Brady. 
The species Vummulites cumingii is confined to tropical and sub- 
tropical latitudes and is found only in very shallow waters. In speci- 
mens from Station D. 4000 there are fourteen chambers in the final 
convolution. In Nuwmmulites radiata the number is much greater 
(nearly double), and they are more sinuous. Also the shell is of a 
dark brown color in Nummulites radiata and somewhat smaller. 
Stations D. 4000, H. 4476, H. 4566 (7), and H. 4590. Not as abun- 
dant as Amphistegina at any of the above stations. 
NUMMULITES RADIATA d’Orbigny. 
Nummulina radiata D’ORBIGNY, Foram. Foss. Vien., 1846, p. 115, pl. v, figs. 
23, 24. 
Test compressed, discoidal, smooth, and composed of over twenty 
seoments in the final convolution, separated by flexed septa, some- 
what irregular. Considered by d’Orbigny as related to Vummulina 
lenticularis, but with its chambers more inflected. D’Orbigny’s speci- 
mens were from the Nussdorf Miocene. ‘Two examples of this type 
were taken at Station H. 4476.
