Incertebrata from the Neocornian of Kansas. — Cragin. 5 
ters ; so that the generic position must, for the present, re- 
main somewhat doubtful, the provisional generic reference 
being based upon the shape and general aspect. The species, 
however, is so strongly marked by its exquisite ornamentation 
that it cannot be mistaken for any other with which I am 
acquainted. It is named in honor of my wife. 
REMONDIA FERRISSI Cragin.

The illustration is from a drawing of the type-specimen 
made in 1889. when the original description of the species 
(published in Bull. Washb. Coll. Lab. Nat. Hist., Vol. 2, No. 
10, Dec. 1889, p. 68) was prepared. 
Attention may here be called to some errors which crept 
into that description. In the fourth line of the description. 
the ratio. '"3:7." should read 7:3. In the fifth and tenth 
lines, the word, '•convex," should read, concave. 
The type was from No. 3 of the Belvidere section; but the 
writer has recently collected several other examples in No. 5, 
south of the Belvidere railway station. These agree well in 
size and outline with the type, and show that the latter was 
an adult specimen, and that the species is quite distinct from 
the Sonoran R.furcata Gabb. But some of them present an 
ornamental feature not observed in the type, in having a se- 
ries of several parallel, oblique folds, trending backward and 
a little upward on the umbonal region. The crests of these 
folds are acute, though low. and the troughs are broad and 
shallow. 
CARDITA BELVIDERENSIS. sp. nov. 
Plate I. li-s. !i-11. 
Shell of small to medium size, triangular or cardiform, 
moderately to rather strongly ventricose; beaks placed near 
the anterior side and directed strongly forward; exterior of 
either valve ornamented with about 26 ribs, Of which 111 or 20 
are narrow, prominent. spinigerOUS, and separated by valleys 
about twice as wide as t heinselves. the other 6 or t herea bout 
being low. plainer, and crowded: spines of the larger ribs 
much more closely set than the ribs t heinselves. short, erect. 
subtruncate (commonly appearing as little more than coarse 
granules owing to the weathering of the shell) ; margin of 
valves deeply notched.
