of the Hawaiian Islands; Sidebottom from the east coast of Australia, 

 and Heron-Allen and Earland, the Kerimba Archipelago, from Lord 

 Howe Island, and from the Antarctic Expedition. Egger's speci- 

 mens were from off western Australia and Mauritius. 



I have recorded the species from numerous stations in the North 

 Pacific from Hawaii to Japan; in the Philippine region, and from 

 Samoa. 



Unless more than one species is involved, this is much more widely 

 distributed than other species of the genus. 



Egger records it from the Cretaceous of central Europe, but his 

 figure in end view certainly does not have the apertural characters 

 of S. columeUaris. 



SIPHOGENERINA COLUMELLARIS (H. B. Brady), var. NODOSAROIDES Schubert 



Sagrina raphanus Parker and Jones, var. nodosaroides Schubert, Abhandl. 

 geol. Reichs., vol. 20, pt. 4, 1911, p. 88, text figures 8, 9a, b. 



Under the above name Schubert figures a very long, slender form, 

 with smooth surface and 14 chambers in the uniserial portion. There 

 is no neck or lip, and the entire appearance is that of Sl columeUaris 

 rather than raphanus, and it apparently should be placed as a variety 

 of the former. It is more slender than the typical, and has a few 

 more chambers. The type of the variety was from coral sand of 

 Maria Island in the Paumotu Group, 



SIPHOGENERINA COLUMELLARIS (H. B. Brady), var. SEMISTRIATA Schubert 



Sagrina raphanus Parker and Jones, var. semistriata Schubert, Abhandl. 

 geol. Reichs., vol. 20, pt. 4, 1911, p. 89, text figures 10a, b. 



Schubert describes and figures a form which has the latter half of 

 the test smooth, the earlier portion with numerous slight costae. 

 The general form of the test and the apertural characters very 

 strongly suggest S. columeUaris. His specimen was from the Pteropod 

 clays of Sainabas in the Bismarck Archipelago, late Tertiary in age. 



SIPHOGENERINA HUGHESI Cushman 



Siphogencrina hughesi Cushman, Cushman Lab. Foram. Res., vol. 1, pt. 2, 

 1925, p. 36, pi. 7, figs. 4a, b. 



Test elongate, fairly thick, two or three times as long as broad, 

 circular in transverse section; chambers short and broad, the early 

 chambers irregularly spiral, later ones uniserial; sutures distinct and 

 depressed; wall thick, the exterior smooth throughout; aperture 

 terminal, rounded, with a short neck and slight lip. 



Length 1 mm. or slightly more; breadth 0.50 mm. 



Holotype (Cushman Coll. No. 4364) from the Miocene Monterey 

 shales near Chimney Rock, San Luis Obispo County, California. 



The species is named for Donald D. Hughes, paleontologist of 

 California,
