BUFFONELLARIA LOCULIFERA, new species 



Plate 34, figs. 9, 10 



Description. — The zoarium encrusts pebbles, shells, and orbitoid 

 foraminifera. The zooecia are distinct, separated by an elongated 

 furrow, subrectangular; the frontal is convex and bears a large 

 semicircular area with salient walls at the middle of which the ovicell 

 is developed. The apertura is suborbicular with a broad triangular 

 sinus; the peristome is thin, little salient. The ovicell is very salient, 

 globular, smooth, fragile; it is never closed by the operculum. On 

 each side of the apertura there is a small salient avicularium, adjacent 

 to the peristome.

F [la -0.08-0.09 mm. Us =0.30 mm. 



Variations. — The young marginal zooecia have absolutely the 



aspect of Stephanosella oiaperta Michelin, 1848; but their frontal is 



uniquely an olocyst only and presents no traces of perforations. 



The ovicell is always much smaller than the area in which it is 



developed. Beyond this area the frontal bears another semicircular 



line arranged inversely turning arouml the apertura and terminating 



laterally at the small avicularia. 



The surface covered by young zooecia is generally rather small 



but, however, on the young colonies the cellules with thread like ridges 



are sometimes very rare. 



Affinities. — This species can be compared only to Buffonellaria 



reticulata Canu and Bassler, 1928 from the Gulf of Mexico but 



differs from it in its two semicircular ridges arranged in inverse 



direction quite regularly. Our specimens were living and were in 



reproduction July 29, 1909.
