 TEXTULARIA

(With One Plate) 



In the collections of the Johnson-Smithsonian Deep-Sea Expedition 

 of the cruise of 1933 have been found two species of the genus Tex- 

 tiilaria, which are apparently undescribed forms. 



TEXTULARIA CALVA, n. sp. 



Plate I, figs. I, 2 



Test very large, elongate, roughly triangular in front and side views, 

 almost circular in end view, initial end slightly compressed, pointed in 

 the microspheric form, and rounded in the megalospheric form ; 

 chambers numerous, low and broad, increasing in height gradually as 

 added ; sutures indistinct except in early portion, somewhat depressed, 

 straight, and slightly oblique ; wall coarsely arenaceous, composed of 

 sand grains and calcareous fragments, very roughly finished except on 

 apertural face, where it is rather smoothly finished ; aperture, a very 

 low, broad opening at the base of the inner margin of the last-formed 

 chamber; color gray. Length of holotype 1.60 mm; width 1.04 mm; 

 thickness i.OO mm. 



Holotype. — U.S.N.M. no. 26179; f^om station 25, latitude i8°32' 

 15" N., longitude 66°22'io" W. to latitude i8°32'o5" N., longitude 

 66°22'io" W., 240 to 300 fathoms. 



In addition to the type locality, I have specimens from station 13, 

 latitude i8°3i'o5" N.", longitude 66°02'i5"W. to latitude i8°3o' 

 30" N., longitude 66°04'o5" \N ., 200 to 300 fathoms; and station 93, 

 latitude i8°38'oo" N., longitude 65°09'3o" W. to latitude i8°37'45" 

 N., longitude 65°05'oo" W., 350 to 400 fathoms. 



This species is similar in some respects to Textnlaria gocsii Cushman 

 from the Pacific Ocean near the Hawaiian Islands. T. gocsii differs, 

 however, in being more smoothly finished, in having curved sutures, a 

 flattish apertural face, and in having the upper edge of each chamber 

 slightly overhanging.
