DESCRIPTIVE CATALOGUE OF RECENT FORAMINIFERA. 277 



Localities. — West coast of Cuba, south of Black Island, west coast of 

 Patagonia, (stations 2352, 2584, 2784, 3080), 93 to 541 fathoms. 



HAPLOPHRAGMIUM CANARIENSE d'Orbigny. 

 (Plate 20, fig. 3.) 



Planospiral, much compressed, especially the earlier convolutions, 

 the segments of the final convolution more or less inflated; structure 

 coarsely arenaceous; surface rough; color reddish to grayish-brown; 

 aperture a short transverse slit, with thin projecting lips, situated near 

 the inner margin of the last segment. Diameter, about 1.25 mm. (,f - 

 inch). 



Localities. — Off Nantucket shoals, south of Black Island, and coast 

 of Oregon (stations 2251, 2584, 3080), 43 to 540 fathoms. 



HAPLOPHRAGMIUM GLOBIGERINIFORME Parker and Jones. 



(Plate 21, fig. 1.) 



Has the same form as Globigerina buUoidcs, being composed of a series 

 of gradually enlarging segments arranged spirally around a perpen- 

 dicular axis, all the segments being visible on one face of the shell, and 

 only the final convolution on the other. Walls composed of rather coarse 

 sand, firmly and neatly cemented; color brown; aperture at the central 

 margin of the final convolution. Size very variable. 



Localities. — Off Nantucket Shoals, off Cape Hatteras, southeast of 

 Marthas Vineyard, off coast of Brazil (stations 2041,2115,2508,2760), 

 840 to 1,780 fathoms. 



Genus HAPLOSTICHE. 



Test free, uniserial, straight or arcuate; never spiral; chambers laby- 

 rinthic. 



HAPLOSTICHE SOLDANII Jones and Parker. 

 (Plate 21, fig. 3.) 



Elongate, cylindrical or tapering, rounded at the extremities, con- 

 sisting of several (five to ten) chambers arranged in linear series; 

 segments slightly embracing, lines of union indistinct; texture coarsely 

 arenaceous; color light-gray; chambers subdivided by secondary septa; 

 aperture porous or branched. Length, about 3 mm. (£ inch). Section 

 shows the structure of the walls, the arrangement of the chambers and 

 their labyrinthic character. 



Localities.— Gulf of Mexico (stations 2377, 2399), 210 and 19G fathoms. 



Subfamily TROCH^lMTvlIISriN'^E. 



Test thin, composed of minute sand grains incorporated with calcare- 

 ous or other inorganic cement, or embedded in a chitinous membrane; 

 exterior smooth, often polished; interior smooth or (rarely) reticulated, 

 never labyrinthic.
