 coinnioiily off the coast of the Britisli Isles, so far as the' material I 

 liave had shows, but no specimens were found in the western Atlantic 

 material referable to it.

 pt. 64, 1913, p. 74, pi. 6, fig. 4. 



Description. — "Test chrysalidiform, tapering at both extremities, 

 the aboral end much more acute than the oral, which is neatly rounded 

 off. Aboral extremity either pointed or slightly tumescent at the 

 apex; surface smooth, somewhat dull, but girdled at intervals by 

 four to six clear lines in the shell-substance which enhance the general 

 resemblance of the shell to the chrysalis of a moth. Length, 0.21 mm. ; 

 breadth, 0.08 mm. Aperture simple. There is a slight constriction 

 in the shell wall on either side of the clear lines. 



" The general appearance of this little test is glanduline, resembling 

 a minute specimen of Nodosaria radicula, but there is no trace what- 

 ever of internal septa. 



" Three specimens found at station 13 (Inishgowla harbour, 4 

 fathoms)." 



This is the only record for this species.
