ART. 25 GENERA SIPHOGENERINA AND PAVONINA — CUSHMAN 7 



SIPHOGENERINA REEDI Cushman 



Siphogenerina reedi Cushman, Cushman Lab. Foram. Res., vol. 1, pt. 1, 

 1925, p. 3, pi. 4, fig. 4. 



Test about twice as Ions: as broad, greatest breadth at tlie apertural 

 end, thence gradually tapering to the initial end; chambers distinct; 

 sutures somewhat depressed, strongly curved; wall ornamented with 

 about fifteen lamellate costae which may continue onto the last- 

 formed chamber; apertural characters obscure. 



Length up to 1.10 mm.; breadth 0.50 mm. 



Type specimens (Cushman Coll. No. 4326) from Monterey shale, 

 sec. 24, T. 28 S., R. 14 E., San Luis Obispo County, California, col- 

 lected by W. D. Kleinpell. 



This may be distinguished from S. collomi by its smaller size and 

 greater number of costae. It is nearest the form I have described 

 from the Panama Canal Zone as S. raijhanus (Parker and Jones), 

 var, transversus Cushman. 



It is named for Ralph D. Reed, geologist of California, under whose 

 direction the material was collected. 



SIPHOGENERINA KLEINPELLI Cushman 



Siphogenerina kleinpelli Cushman, Cushman Lab. Foram. Res., vol. 1, 

 pt. 1, 1925, p. 3, pi. 4, fig. 5. 



Test about twice as long as broad, greatest breadth at the aper- 

 tural end, thence irregularly tapering to the initial end; chambers 

 distinct; sutures depressed, very slightly if at all curved; wall orna- 

 mented with about fifteen very low costae, not at all lamellate, not 

 continuing onto the last-formed chamber; aperture with a very short 

 cylindrical neck and slight phialine lip. 



Length up to 1 mm.; breadth 0.50 mm. 



Type specimens (Cushman Coll. No. 4327) from Monterey shale, 

 sec. 24, T. 28 S., R. 14 E., San Luis Obispo County, California, col- 

 lected by W. D. Kleinpell, 



This species may be distinguished from S. reedi by the much lower 

 and less prominent costae, and the lack of curvature in the sutures. 



It is named for W. D. Kleinpell who collected the material.
