ART. 6 FORAMINIFEKA: POLYMORPHINIDAE — CUSHMAN AND OZAWA 19 

 QUADRULINA FEONDICULARIOIDES (Chapman) 



Plate 1, figures 5 a, b 



Polymorphina frondicularioides Chapman, Quart. Journ. Geol. Soc, vol. 50, 

 1894, p. 716, pi. 34, figs. 13 a, b. 



"Test subpyriform, but somewhat compressed, tapering more 

 acutely towards the aboral extremity; test rhomboidal in section, 

 surface smooth, and swollen along the centre of each face. About 

 six^chambers are visible on each surface, slightly inflated, and bordered 

 by^well marked sutures. The last chamber is pinched up towards 

 the apex; but it embraces the whole width of the test, after the man- 

 ner of Frondicularia and Lingulina. Aperture slightly elongate, with 

 a stellate border. Length one sixty-sixth inch (0.37 mm.), width one 

 one-hundred-and-thirtieth inch (0.19 mm.). 



"This form also appears to represent a new genus or subgenus, 

 combining two hitherto distinct generic types. 



"One specimen from the pebble bed, Littleton." 



We have no specimen of the present species. 



The above is quoted directly from Chapman, and the figures are 

 copied from his plate. 



QUADRULINA LAGENALIS (Terquem) 



Plate 1, figures 6 a, 6 



Polymorphina lagenalis Terquem, Quatr. Mem. Foram. Lias, 1864, p. 301, 

 pi. 13, figs. 39a, b. 



Terquem's description of the species runs as follows : 



P. testa laevigata, elongata, ovata, rotundata, postice obtusa, antice succisa, 

 lateribus aequali, loculis septem alanis, quatuor induplice cruce dispositis, uno in 

 medio quadrangular!, apertura magna, long. 0.58 mm. 



Locality: Quenleu-les-Metz, lower Lias. 



This is a distinctive species having a tetraloculine arrangement of 

 chambers and is here copied in order to show a Jurassic example of 

 the genus. 



Terquem's figures are not sufficient to show completely the tetraloc- 

 uline arrangement of chambers.
