face highly convex; inferior less convex, slightly excavated at the 

 umbilicus; peripheral edge thick and lobulated; segments inflated, 

 especially those of the final convolution. Colour deep brown, except 

 the terminal segment, which is generally of lighter hue. Diameter, 

 K30 inch (0.2 mm.)." 



The only Challenger record for this species is the type station, No. 5, 

 southwest of the Canaries, 2,740 fathoms. Similar forms have been 

 recorded from the Antarctic and from the Pacific. 



The description and figures are from Brady,

Wright figured two distinct things in his paper referred to above. 

 The second of these was placed by Brady in his Discorbina vyrightii. 

 It has a trochoid test, the ventral side concave, and a stellate form in 

 the umbilical region. The ventral side is marked by beads in radial 

 lines, Brady 's figure of a specimen from Nova Zembla is given here, 

 and seems to be an Eponides. It may be noted that the form de- 

 scribed by Heron- Allen and Earland as "Discorbina baccata" from 

 the Clare Island region very strongly resembles Wright's original 

 figure. Their description mentions the beads of the ventral surface 

 arranged in radial lines, but their figure does not show this clearly. 

 The umbilical stellate ornamentation is very clearly similar in the 

 two, and the dorsal and side views are very close.
