NO. II FORAMINIFERA OF VENEZUELA — GRAVELL I9 



diameter, arranged in annular rings. The annular and radial walls 

 are about 20 ju. thick. The specimens were too poorly preserved to 

 permit determination of the type of communication between the 

 median chambers. 



The specimens occur in limestone. As it was impossible to remove 

 them from the matrix, the margins of the test could not be examined. 

 Several thin sections were made, but these did not yield sections from 

 which the species or even the genus might safely be determined. 

 However, these specimens appear to be much closer to Amphisonts 

 than to Orhitolites. 



Locality and geologic horizon. — From locality 468 in limestone 

 lenses in the Agua Clara shales, which are believed to be upper 

 Oligocene. 



Dr. H. G. Kugler has informed Dr. T. Wayland \^aughan that 

 these specimens have been identified as Orhitolites sanluisensis Hod- 

 son. I have thus far been unable to find any description or mention 

 of this species in the literature.
