breadth 2 mm. Subrostrum with the same characteristics as ros- 
trum, except that itissmaller. Carino-laterals long, triangular, with 
apex distal, smooth, length romm. Maximum breadth 4 mm. 
Superior laterals shorter 3 mm.; otherwise much the same as ca1ino 
lateral. Peduncle short, composed of seven rows of plates; plates 
oblong, narrow, overlapping, short; maximum breadth 6 mm. 
The type specimen was collected from the base of the Ornithos-

Squama lata, n. sp. 
Capitulum composed of ten plates, viz.; carina, targa (2), scuta 
(2), subcarina, superior laterals (2), carino-laterals (2): height 8 
mm.; widtr 16 mm. Carina long, narrow, rounded, slightly con- 
vex, the surface marked by parallel striae; height 4 mm., breadth 
2mm. Terge triangular, with the base rounded; slightly convex, 
the surface smooth; length 8 mm., maximum breadth 4mm. Scuta 
large, convex, quadrangular, its superior lateral border somewhat 
rounded; rostral border straight, surface marked; length 8 mm., 
breadth 5mm. Carino-laterals long, triangular, the surface marked 
by transverse lines; length 8 mm., breadth 3mm. Superior laterals 
shorter, resembling the carino-laterals in general shape. Peduncle 
short, its maximum breadth 6 mm.; composed of seven rows of 
plates; plates quadrangular, with the upper border curved; six or 
seven larger plates in the upper part of a row, succeeded below by 
about ten very much smaller ones. 
Type specimen adhering to Inoceramus shell by its entire length. 
The type specimen was presented by Mr. M. R. Watson, of Trego

upper Niobrara. 
Stramentum, Gen. Nov. 
Capitulum composed of eight or nine plates; plates of the 
peduncle narrow, with the ends turned down, presenting a thatched 
appearance; plates each with a groove running longitudinally. 
The two known species of this genus are evidently from a higher 
horizon than those previously described, coming from the yellow 
chalk, or the same beds that contain the toothed birds.
