tinique and Angola. The species from Panama was recorded by 

 Dall and by Bagg as Orbitoides forbesi Carpenter. 1 



Cat. No. 135216, U.S.N.M., is Lepidocyclina canellei Lemoine and 

 Douville. Figures 1, 4-6, on plate 34 are from this material, col- 

 lected by Hill at Bohio, Panama, where it is very abundant. This 

 is the same locality as station 6027 of Vaughan and MacDonald, 

 orbitoidal marl, a quarter of a mile northwest of Bohio railroad 

 station. In this material L. canellei is very abundant and makes up 

 a considerable proportion of the marl. Parts of five specimens, close 

 to one another, are visible in a small part of a section from this 

 station. 



Specimens in the collection of the United States National Mu- 

 seum, Catalogue No. 107158, from the Oligocene of Trinidad ("Leda 

 bed," Naparima) collected by Guppy, are also very evidently Lepido- 

 cyclina canellei. 



Specimens of L. canellei were also very abundant at station 6891, 

 foraminiferal limestone from Bailamonas, Canal Zone, collected by 

 D. F. MacDonald. 



There is a limestone from station 6892, 450 feet south of switch 

 at Mamei, Canal Zone, also collected by MacDonald, which contains 

 numerous specimens of a Lepidocyclina in general shape in section 

 resembling L. canellei, but the material is very cherty and the finer 

 structure is not well preserved. 



A few small weathered specimens from 6019<2, Gaillard Cut, oppo- 

 site Las Cascadas, seem to belong to this species also ; and specimens 

 were also obtained at station 6023, along the relocated line of the 

 Panama Railroad, at Rio Frijol. The geologic occurrence is in the 

 Culebra formation.

Test of medium size, diameter from 8 to 20 millimeters, circular in 

 outline, somewhat saddle-shaped, central portion slightly thickened,

 where well preserved slightly papillate, usually roughened by ero- 

 sion, toward the periphery often somewhat reticulately depressed 

 above the equatorial chambers. 



Vertical section usually curved, lateral chambers numerous, 

 breadth much greater than height, columns separated by distinct 

 pillars, comparatively few except in the central region where there
