2 PROCEEDINGS OF THE NATIONAL, MUSEUM. vol. 64. 



Geologists of the South American Gulf Oil Co. recently deposited 

 in the United States National Museum collections of Tertiary fossils 

 from the Province of Pinar del Rio, Republic of Cuba. A collection 

 from the Consolacion limestone at a locality 5.6 kilometers north- 

 east of San Cristobal (U.S.G.S. station 1/186) contains the small 

 specimen of Orthaulax aguadillensis Maury figured on Plate 2, 

 Figure 4. The rock in the body cavity of this specimen contains nests 

 of Miogypsina antiUea (Cushman). Small shells and casts of 

 Orthaulax oaepa Cooke were obtained in the same region and from 

 the same limestone at the following localities : upper Oligocene, Con- 

 solacion limestone 8 kilometers west of Taco-Taco, W. Gretzinger 

 collector, four specimens, U.S.G.S. station 1/181; Consolacion del 

 Sur, W. Gretzinger, collector, five specimens (casts, identification 

 doubtful), U.S.G.S. station 1/183. 



Wythe Cooke, of the United States Geological Survey, has re- 

 cently identified a specimen of Orthaulax gdbbi Dall collected by 

 Bruce Wade, of the Transcontinental Oil Co., at the Topila Hills, 

 25 kilometers southwest of Tampico, Vera Cruz, Mexico. Mr. Cooke 

 has kindly given the following heretofore unpublished records of 

 Orthaulax pugnax (Heilprin) : U.S.G.S. station 1/103, Glendon 

 limestone, sec. 25, T. 4 N., R. 20 E., on road to Elba, 1.1 kilometers, 

 north of Goodman, Coffee County, Alabama, W. Cooke, and J. Gard- 

 ner, collectors. May 12, 1921; U.S.G.S. station 1/104, Glendon lime- 

 stone. Holmes County, Florida, 0.8 kilometer south of the State line 

 on road from Geneva, Alabama, to Westville, Florida, W. Cooke and 

 J. Gardner, collectors, June 9, 1921 ; U.S.G.S. station 1/106, Glendon 

 limestone, 3.8 kilometers from Geneva, Ala., on road to Vaughan- 

 ville, Alabama, W. Cooke and J. Gardner, collectors. May 10, 1921. 

 The faunal associates of Orthaulax pugnax at these localities and 

 their stratigraphic significance are given by Cooke in a paper await- 

 ing publication by the United States Geological Survey. Dr. C. A. 

 Matley, Government geologist of Jamaica, has recently collected 

 Orthaulax pugnax from beds of middle Oligocene age near Jack- 

 son Town, Jamaica; and Orthaulax aguadillensis from beds of lower 

 Miocene age near May Pen, Jamaica. 



The preceding records bring up to date all the known localities for 

 the genus. 



THE GENUS ORTHAULAX. 



Orthaulax is a peculiar stromboid mollusk found only in the tropi- 

 cal and subtropical faunas of middle Oligocene (Rupelian), upper 

 Oligocene (Aquitanian), and lower Miocene (Burdigalian) age in 

 the West Indies, Central America, Mexico, and southeastern United 

 States. The genus thus has a restricted stratigraphic and geographic 

 range. It was described by Gabb in 1872.* The genotype is O. in-
