8 SMITHSONIAX MISCELLANEOUS COLLECTIONS VOL. 9I 



GLANDULINA SPINATA, n. sp. 



Plate 3, figs. 8, 9 



Test oval or broadly elliptical in front view, with apertiiral end 

 somewhat produced, circular in transverse section ; chambers in the 

 early portion apparently biserial, later uniserial, much involute ; sutures 

 largely obscured by the surface ornamentation ; wall calcareous, per- 

 forate, rather uniformly covered with short, blunt spines; aperture 

 elliptical, at the end of a short neck with a somewhat flaring lip. 

 Length 0.45-0.50 mm ; diameter 0.30 mm. 



Holotype. — U.S.N.M. no. 26204; from station 56, latitude 19° 10' 

 15" N., longitude 69°27'2o" W. to latitude i9°io'i5" N., longitude 

 69°28'o5" W., 17 fathoms. 



This species apparently belongs in the genus Glandulina, and is to be 

 distinguished from other species of that genus by its peculiar surface 

 ornamentation. 



EHRENBERGINA SPINEA, n. sp. 



Plate 3, figs. 10, II 



Test somewhat compressed, in the adult in front view somewhat 

 rhomboid, with each side extended out into an acicular spine, dorsal 

 view with the sides broadly rounded ; chambers distinct, only slightly 

 inflated; sutures distinct, somewhat limbate, little if at all depressed; 

 wall smooth, calcareous, finely perforate ; aperture narrow, elongate. 

 Height 0.35 mm ; breadth including spines 0.60 mm. 



Holotype. — U.S.N.M. no. 26207; from station 13, latitude i8°3i' 

 05" N., longitude 66°02'i5"W. to latitude i8°3o'3o" N., longitude 

 66°04'o5" W., 200 to 300 fathoms. 



This species most closely resembles that described by Brady from 

 the Pliocene of the Pacific, as Ehrenhergina bicornis. Our Atlantic 

 species however is smaller and much more compressed, with the spines 

 much less developed. 



PEGIDIA CORRUGATA, n. sp. 



Plate 3, figs. 12, 13 



Test plano-convex, the dorsal side strongly convex, ventral side 

 flattened, periphery rounded ; chambers rather indistinct, four or five 

 making up the last-formed whorl in the adult and largely visible on the 

 dorsal side, ventral side much obscured by the peculiar surface orna- 

 mentation ; sutures largely obscured, strongly curved, sigmoid on the 

 dorsal side ; wall calcareous, distinctly but finely perforate, the dorsal 

 side fairly smooth, ventral side strongly rugose with a peculiar laby-
