The following is a description of this species: 



Test strongly compressed in a plane parallel to that of the junction between 

 the chambers, which are biserially arranged, nearly as wide as long, the 

 sutures appearing at the narrow sides of the test, outline from the flattened 

 side triangular, the apertural end broad and slightly convex, initial end 

 pointed, in side view test narrow with nearly parallel sides, chambers slightly 

 inflated, sutures slightly depressed, wall arenaceous with an abundance of 

 cement, smoothly finished exteriorly; aperture extending nearly the entire 

 width of the test, divided into a series of smaller circular or elliptical openings 

 by prolongations of the apertural wall. 



Length up to 4 mm. or slightly more; breadth equal to the length. 



This is one of the commonest and most striking of the Bowden 

 species. D'Orbigny's figure shows a specimen fully as broad as long 

 and from its early stages being very broad. In the Bowden material 

 there are two forms which, although they vary somewhat, seem never- 

 theless worthy of distinction. 



Cuneolina pavonia d'Orbigny var. angusta, new variety. 

 (Plate 7, Figure 2.) 

 The following is a description of this variety: 



Test differing from the typical in its much narrower form, the length 

 usually twice the width, slightly thicker than the typical, the chambers 

 occasionally showing a tendency toward an angle in the center. 



Length up to 5 mm. or more. 



This narrower variety is much more common than the broader 

 typical form. Vanden Broeck did not record it from his material off 

 Barbados, but it occurs in considerable numbers there in 100 fathoms 

 with Haplostiche dubia var. intermedia Vanden Broeck and other species. 

 It is also met with rather frequently off our eastern coast, although it is 

 practically unrecorded as a recent species. 



Verneuilina spinulosa Reuss. 



Vcrneuilina spinulosa Reuss, Denkschr. Akad. Wiss. Wien, vol. 1, p. 374, plate 47, fig. 12, 

 1850; H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, p. 384, plate 47, figs. 

 1 to 3, 1884. 



The species is represented by a single specimen, very typical in all 

 its characters, from station 3461, from marl, gorge of Yumurf River, 

 Matanzas, Cuba, T. W. Vaughan, collector.
