lO SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 89 



The Antiguan Oligocene and the San Luis series contain the follow- 

 ing species in common: L. {Ncphrolcpidina) undosa Cushman, L. 

 (Eulepidina) favosa Cushman, Lcpidocydina gigas Cushman, and L. 

 (Lepidocyclina) forresti Vaughan. 



The San Luis series may also be correlated with the Oligocene of 

 Panama. 



The following species have been reported from the Oligocene of 

 Panama by Cushman (12, pp. 94-97) : L. (Lepidocyclina) canellei 

 Lemoine and R. Douville, specimens which Cushman referred to as 

 Lepidocyclina chaperi Lemoine and R. Douville (Vaughan, 47, p. 798, 

 states that the Lepidocyclina chaperi of Cushman from the Panama 

 Canal zone is not L. chaperi Lemoine and R. Douville) ; L. (Nephro- 

 lepidiria.) vaiiglianl Cushman; and Miogypsina panamensis (Cush- 

 man). In the same paper Cushman also described L. (Lepidocyclina) 

 macdonaldi Cushman, and L. (P Hole pi din a) duplicata Cushman from 

 strata in Panama which were at that time considered Oligocene, and 

 tentatively placed L. (Pliolepidina) panamensis Cushman in the 

 Oligocene. Vaughan (47, pp. 796-797) places L. macdonaldi and L. 

 duplicata in the Eocene. He also tentatively placed L. panamensis 

 in the Oligocene. Vaughan has reported and described the following 

 species from Panama (47, p. 813, pi. 36, figs. 4-6) : Miogypsina 

 cushmani Vaughan from the upper part of the Culebra formation, an 

 undescribed species of Heterostegina (47, p. 789) from the Culebra 

 formation at Bohio Ridge Switch, and L. (Lepidocyclina) mira- 

 florensis Vaughan (55, p. 4, figs. 3-5), " The horizon is supposed to 

 be the lower Miocene, Emperador limestone, but the stratigraphic 

 position is not definitely known." 



The following species are common to the San Luis series of Vene- 

 zuela and the Oligocene of Panama : L. canellei and the undescribed 

 species of Heterostegina reported from Panama by Vaughan, which 

 is described in this paper as Heterostegina panamensis Gravell, n. sp. 



As the stratigraphic relations of the lower Tertiary formations of 

 Panama are still somewhat uncertain, only the general relationships of 

 the San Luis series of Venezuela to the Oligocene of Panama are 

 indicated. 



The San Luis series may also be correlated with the Oligocene of 

 Jamaica, which is represented by the Moneague formation and at least 

 part of the Montpelier white limestone. Vaughan (57, p. 280) lists 

 their faunas as follows : 



Moneague formation : L. (Lepidocyclina) canellei Lemoine and 

 R. Douville, L. (Lepidocyclina) yurnagunensis Cushman, L. 

 (Lepidocyclina) miraflorensis Vaughan, L. (Lepidocyclina) forresti
