﻿2 SlDEBOTTOM, Nevillina, a Neiv Genus of Foraminifera. 



Mr. Millett's description of Biloculina coronata, in the 

 above reference, reads as follows : 



" Test fusiform, chambers few and inflated, sutures 

 depressed, aperture circular, surmounted by a series of 

 incurved lamellae, which approach or inosculate over the 

 centre of the aperture. Shell-wall thin, translucent, and 

 much wrinkled, length 0*58 mm." He also adds " It is 

 very rare, being represented by a solitary specimen from 

 station 18." 



It is evident to me, judging from the range of 

 specimens that I have found, and from Mr. Millett's 

 figures and description, that his solitary specimen is an 

 immature (and probably malformed) example of the 

 species which I found in the adult state, and for which I 

 now create the new genus Nevillina, thus associating 

 with it the name of my brother-in-law, Mr. Nevill, of 

 Bramall Hall, Cheshire, to whom I am indebted for so 

 many dredgings. These specimens were obtained from 

 dredgings made by Captain Lunham,of the S.Y. "Victoria," 

 for Mr. Nevill, and were given to me by the latter for 

 examination. 



If I am right in my conclusions (and they are con- 

 firmed by M. Chas. Schlumberger, of Paris, who, with his 

 usual kindness, examined my section, drawings, and 

 specimens) it follows that Mr. Millett's example does not 

 belong to the genus Biloculina, and may with propriety 

 be transferred to the genus Nevillina. 



It will be noticed that the arrangement of the 

 chambers, and their plan of growth, are in some respects 

 the same as in the Chilostomellida:.
