204. THE AMERICAN MIDLAND NATURALIST 
Genus Uniomerus Conrad. 
1853-—— Uniomerus Conrad, Proc. Ac. Nat. Sci. Phila, VI, p. 268. (as 
genus). 
1900b— Uniomerus (Conrad) Simpson, Proc. U. S. Nat. Mus., XXII, 
Pp. 739 (as section). 
(Type, Unio tetralasmus Say). 
ANIMAL CHARACTERS:—Both branchial and anal openings 
papillose and crenulate; supra-anal closely and loosely connected 
to anal; inner laminae of inner gills free from the visceral mass 
almost their full length; papli short almost as wide as long; color 
of soft parts mostly a soiled white, gills brownish; gills only mar- 
supial in outer ones, when gravid rather distended lengthwise 
in center, tapering at the ventral edge, ovisacs not divided; septa 
wavy; conglutinates white, sole-shaped; glochidia medium in 
size, semielliptical, higher than long, hinge line straight. 
SHELL CHARACTERS: — Shell trapezoidal, rather obtusely 
pointed behind; disk smooth with the exception of roughened 
growth lines; beaks low, sculptured with several coarse concentric 
ridges which curve abruptly upward behind where they are 
crowded closely together; epidermis rayless, shiny, yellowish 
to black; cardinals compressed; laterals nearly straight; nacre 
whitish to bluish. 
MISCELLANEOUS REMARKS:—Dr. Ortmann elevates Unio- 
merus from Simpson’s treatment of it as section mostly because of 
the peculiar beak sculpture of its type since this character alone 
is a great departure from the Flliptio-shell (See Plate xx1, fig. 69). 
Then, too, the shell is thinner, has more of a rayless, vari-colored 
polished epidermis and is more elongated with less curved dorsal 
or ventral line. 
OUR BIRDS IN THE SUMMER OF 10914. 
BY BROTHER ALPHONSUS, C. S. C. 
In this article I have recorded the more interesting of my 
observations made during the summer of 1914, in the hope that 
they may be found serviceable especially to students of bird 
life who may not have equal opportunities to observe birds in 
their native haunts. Very few persons, like the writer, can find
