the iiKist prominent, the second less, and the third the least prominent. 

 The base is terminated by a small pedicel. The specimen seems to be a 

 costate variety of Flahellum conoideuin, and prol:)ably is referable to variety 

 ■niatfheivstmsc.

' This species is described from a single specimen. Form triano-ulnr, 

 cuneate ; attached by a pedicel 2 mm. hig'h. The cross section is subellip 

 tical, with subacute angles at the ends of the longer transverse axis. No 

 marginal wings, l)ut the edges are irregular. Costse not prominent, seven 

 or eight on each face, distinct, but low, with rounded transverse profile. 

 Very fine girdling lines of growth, some girdling depressions. Septa rather 

 thick, with granulate sides, arranged in six systems, four complete cycles 

 and 16 of the fifth cycle in the systems next the ends of the longer trans- 

 verse axis. Apparent arrangement eight systems of four complete cycles 

 each.- Interseptal loculi filling with internal calcareous deposit. Columella 

 f( irmed of septal trabecular Greater diameter, about 1 4 mm.; lesser diameter, 

 about 10 mm. ; height, 13 mm.

The distinct pedicel and few low costse characterize this species. It

described later.
