 uniformly narrow, attaining a length of 32 mm and a width of 2 mm (in the 

 compressed state, 1.3 mm ; in majority of specimens) ; rounded at sicular 

 extremity (.05 wide) and rapidly widening, attaining its full width in the 

 length of about 10 thecae ; ventral margins subparallel ; antisicular end not 

 contracted, and abruptly terminating ; sicula only partially visible, virgella 

 present, but short ; lateral spines little developed. Median sutural groove

 angulations short horizontal grooves run out at right angles. Thecae num-

 proximal half parallel to nemacaulus ; and then bending abruptly outward 

 approximately at right angles and again into subparallelism to the nema- 

 caulus with a slight inward inclination ; the apertural margin normal to free
