 Polymorphina translucida Fornasini, Mem. Accad. Sci. Istit. Bologna, ser. 5, 



vol. 10, 1902, p. 52, fig. 51. 



Test ovate, more or less compressed, broadly rounded at the base, 

 tapering toward the apex; chambers few, inflated, much overlapping, 

 arranged in a nearly triserial series; sutures very slightly if at all 

 depressed, distinct; wall smooth, translucent; aperture radiate. 



Length, 0.50-0.85 mm.; breadth, 0.45-0.85 mm.; thickness, 0.25- 

 0.50 mm. 



As in the case of Glohulina gibba, many different specific names are 

 given to divergent forms of the globular, but compressed variety of 

 Glohulina, among which Glohulina inaequalis Reuss has the priority. 

 Glohulina discreta Reuss reported in 1850 from the same locality as 

 the present variety seems to us an abnormal form of the typical. 



Reuss's several names given to the middle Oligocene compressed 

 Globulinas are considered by the authors, after the examination of a 

 great number of topotype specimens to be nothing but individual 

 variations of one species, and they are placed with the Miocene 

 Glohulina inaequalis. Bornemann's Guttulina diluta has a rounded 

 test and is not at all compressed. It might appear to be more reason- 

 able to put it in Glohulina gibba than in inaequalis, but we consider it 

 an abnormal form of the present species, having the later chambers 

 not fully developed. 



Glohulina translucida, named by d'Orbigny and illustrated much 

 later by Terquem as well as by Fornasini, in its every respect is iden- 

 tical with the present species. Guttulina nitida d'Orbign}^, figured 

 by Fornasini, is doubtlessly related to the present one, as it has rather 

 elongate chambers.
