THE FAMILY LAGENID.^ 201 



Dimorphous Foem. 



Genus Sagraina, D'Orbigny, emended by Parker and 



Jones. 



Early segments Uvigerine, later ones Nodosarian. 

 Eocene to Recent. 



Example. — ^. striata, Schwager {Binwrpliina), 

 'Novara-Exped., geol. Theil,' vol. ii. 1866, p. 251, 

 pi. vii. fig. 99. 



The typical Uvigerine commencement is distinctly 

 seen in this species. 



As a recent form >S. striata, seems confined to tropi- 

 cal areas, and ranges in its depth from quite shallow 

 water to 350 fathoms. The fossil examples were 

 obtained from the Eocene beds of Hungary, the 

 Miocene. of Malta, and the Pliocene of Kar Nicobar. 

 Eocene to Becent. (Plate 11, fig. D.) 



Snh-faniil// 4. Kamulinin.e. 



Test commencing with an imperfectly segmented 

 series of chambers, sometimes resembling to a certain 

 extent the simpler forms of Polijiiiorpliina, to which 

 genus the present group bears some affinities ; after- 

 wards branching irregularly and taking the form of 

 subspherical chambers united by long and slender 

 stoloniferous tubes, or a series of pyriform chambers 

 with or without intermediate stoloniferous tubes. 



Genus llajntiluta, Kupert Jones. 

 Test branching, composed of spherical or pyriform
