NO. 3 GLANDULINE NODOSARIIDAE — LOEBLICH AND TAPPAN 5 



north side of road, 2 miles east of Saratoga on road to Columbus, Ark., 

 Deaderick Collection. Unfigured paratype (U.S.N.M. P2014) from 

 the Corsicana marl, 2 miles south of Manda, Travis County, Tex. 

 Unfigured paratype (U.S.N.M. P2015) from the Corsicana marl, on 

 Mexia highway at forks of Wortham road, 2.8 miles ESE of Cooledge, 

 Limestone County, Tex. Unfigured paratypes (U.S.N.M. P2016) 

 from the Taylor marl, Colorado River, i mile NNE of Delvalle, 

 Travis County, Tex. 



Remarks. — Cushman and others had referred this species to Pseu- 

 doglandulina lagenoides (Olszewski) but had also included with it 

 many varying forms, some fusiform, others subcylindrical, some with 

 bluntly rounded base, others with pointed and even apiculate base. 

 The present species differs from Glandulina lagenoides Olszewski in 

 having much lower chambers and in the shape of the test. G. lage- 

 noides has a strongly fusiform test in contrast to the subfusiform out- 

 line of Rectoglandulina appressa. 



RECTOGLANDULINA OBESA Loeblich and Tappan, new species 

 Plate I, figures 5a-6 



Test free, robust, ovate in outline, widest slightly above the midline, 

 base pointed, apertural end broadly rounded, chambers rectilinear, 

 very strongly overlapping, final chamber occupying three-fifths the 

 length of the test ; sutures distinct, horizontal, flush, not constricted ; 

 wall calcareous, hyaline, surface smooth; aperture terminal, radiate. 



Length of holotype 0.47 mm., greatest breadth 0.34 mm. Paratypes 

 range from 0.36 to 0.68 mm. in length and from 0.21 to 0.36 mm. in 

 breadth. 



Types and occurrence. — Holotype (U.S.N.M. P2017), figured para- 

 type (U.S.N.M. P2018), and unfigured paratypes (U.S.N.M. P2019) 

 all from the Ozan sand, Murfreesboro road, 0.9 mile west of Wright's 

 Store at junction of Okolona and Murfreesboro roads, Clark County, 

 Ark., Deaderick Collection. Unfigured paratypes (U.S.N.M. P2020) 

 from the Annona chalk in a natural erosion about one-half mile north 

 of White Cliffs Post Office, Ark., Deaderick Collection. 



Remarks. — This species somewhat resembles Glandulina inflata 

 Bornemann from the Oligocene of Germany but differs in being 

 smaller, in having a more broadly rounded upper surface, rather than 

 a produced aperture, and a more rounded final chamber.
