— 
Some New Cirriped Crustaceans From the 
Niobrara Cretaceous of Kansas. 
BY YW. Nic LOGAN, 
Hitherto but very little has been made known concerning the 
Crustacea of the American Cretaceous. In the following communi- 
cation are given the descriptions of several forms of Cirripeds, 
specimens of which have been collected during the past year or 
two in the western part of Kansas. Their horizon is from the 
lower-most part of the Ornithostoma Beds, and from the Yellow 
Chalk. Figures and further descriptions will be given in Vol. I, of 
the Paleontology of the University Geological Survey, now in 
preparation. 
Squama Gen. Nov. 
Capitulum composed of from nine to twelve plates of medium 
size and sub-triangular; peduncle short, composed of seven rows of 
plates, tapering gradually, to near the extremity, and ending ina 
rapidly, almost abruptly diminishing reflex area of smaller plates; 
form adhering to Inoceramus by its entire length. 
Squama spissa n. sp. 
Capitulum composed of twelve plates, viz.; carina, terga, (2), 
scuta (2), rostrum, subrostrum, subcarina, superior laterals (2), 
and carino-laterals (2). Height of capitulum from base to tip 
1g mm.; width (lateral) from carina to subrostrum 17 mm, Carina 
long, narrow, somewhat shield shaped, and slightly convex; length 
5 mm.; maximum breadth 2 mm., overlapping lateral in one speci- 
men. Torga, triangular, with apex pointing toward base of capi- 
tulum, and base somewhat rounded; very slightly convex smooth; 
length ro mm.; breadth (maximum) 15 mm., joined closely with 
laterals in one specimen. Scuta large, convex, in general shape 
triangular; superior border almost straight; rostral border convex, 
base smooth, slightly concave, length (10) mm.; maximum breadth 
7 mm., adhering closely to superior lateral and overlapped by 
rostrum. Rostrum clubshaped, slightly convex; length 6 mm.,
