SAGRINA, d'Orbigny, emend. Parker and Jones. 



The genus Sagrina makes its first appearance in d'Orbigny's monograpli on 

 the Cuban Foraminifera (1839), and was named by him after de la Sagra, of 

 whose work on the Island it formed an integral part. Broun in 1851, Reuss in 

 1865 (models), Marsson in 1878 and others subsequently, have adopted the name 

 Sagraina. which is obviously more correct in the circumstances. We prefer, 

 however, to adhere to the original spelling. 



The name Siphogenerina was coined by Schlumberger in 1883 to include all 

 those Foraminifera in which the aperture extended in the form of a siphon, or 

 tube, through the successive chambers of growth. This method of classification, 

 though perhaps taxonomically convenient, is false zoologically, because species, 

 widely separated generically, present this feature in common, whereas individuals 

 of the same genus iii some species possess a siphon and in others lack it. Even 

 within the limits of a species the presence or absence of a siphon may be 

 observed, as in Sagrina raphafius, which has sometimes an external neck and no 

 siphon, and in others has no neck, but has the internal tube. Considerable 

 confusion has thus been introduced into synonymies, and we thinlv that 

 Schlumberger' s generic name should be abandoned and the species be redistributed 

 among the genera to which they undoubtedly belong.
