GOES: FORAMINIFERA. ot 
constructed 24—3-whorled spire, with 5-6-7 segments in the outer one. The 
test is sometimes rough with sand grains and a a grayish hue, but sometimes 
polished and of a brown or reddish color, It is more inflated and larger than 
H. nanum Br. (Chall. Rep., Pl. XXXYV. Figs. 6-8), but in all other respects 
of the same build. The umbilicus is sometimes deep, but generally very 
narrow, sometimes wanting. Attains a diameter of 1.5 mm.

spire, approaching H. turbinatum; Fig. 13, umbilical side. 
Pacific. 885-1879 fathoms ; a few starved specimens. 
Caribbean Sea. 380-1630 fathoms; scarce, but well developed specimens.

This may be considered as intermediate between the preceding and ZH. lati- 
dorsatum. The sutures nearly obsolete; the segments are not inflated, but the 
contours thick, the rounded margin without incisions, the aperture sometimes 
situated above the marginal suture on the obliquely set septum ; umbilicus . 
usually obsolete. The outer whorl 6-chambered; color pale yellow; surface 
sometimes smooth, sometimes rough. Diameter, 1-2 mm.

This large and flat form has been met with at three stations only in the 
Pacific. Younger ones are hardly distinguishable from H. compressum Gois. 
Pacific. 660-995 fathoms ; not plenty.

To be considered a pygmy variety of H. fontinense Br. Full grown 
specimens have also the aperture situated on the top of the septal wall ; 
but in those which have not yet put on the Nodosaria stage it is margini- 
sutural. It has often a brown or brick color. 
Caribbean Sea. 196-463 fathoms; not common.
