This species is distinct from L. pallidus, although closely related to it. 
The color is much darker. Each scale has in its center a dark spot, 
longest up and down. The opercular flap is longer and more abruptly 
formed than in L. pallidus. The opercular flap, measuring from where 
the scales cease, is equal to the diameter of the eye, while in DL. pallidus 
it is equal to only two-thirds the eye’s diameter. The pectoral and ven- 
tral fins reach fully to the first anal spine.

While at Enterprise I obtained some small specimens of a Sunfish 
‘which belongs to Professor Jordan’s genus Xenotis. | saw several adult 
specimens, but could procure none from their captors, who took profes- 
sional pride in their long “strings”. My attention was especially 
attracted to this fish by its immense opercular flap. Since returning 
home, Mr. William A. Warner, of Enterprise, has kindly sent me addi- 
tional material, and, among other things, a specimen of this fish, having 
a total length of 6 inches. After a careful study of this species my con- 
clusion is that it is the Pemotis fallax of Baird and Girard, described 
from Northern Texas. The agreement with the description and figures 
given in the Pacific Railroad Survey Report is very close indeed. Fig. 
5, pl. ix, gives a very good although somewhat reduced representation 
of my largest specimen. 
Xenotis solis, Gill & Jor. (Bull. U.S. Nat. Mus. No. 10, 22), not Pomotis 
solis, C. & V. (see Proc. U. S. Nat. Mus. 1879, 225), is a more elongate 
species, the greatest depth being contained 2 24 times in the length in- 
stead of 2, asin my specimens. The eye of that species is contained 
in the flap 14 times instead of 2, as inthis. The flap of that is contained 
24 times in the rest of the head instead of 2 times, as in this. In that 
there are “about 5 rows [of scales] above and 11 below” the lateral line; 
in this there is one more both above and below. 
From P. breviceps, B. & G., it appears to differ in having a larger eye, 
amore anterior dorsal fin, and longer ventral fins; from 1. megalotis, 
in that the body is not so heavy anteriorly. 
I cannot give a description of the colors in life, except that they are 
brilliant. In spirits the body above is yellowish brown, the sc ales being 
dark-edged; fins dusky, narrow blue stripes on the cheeks; flap jet- 
black, with a pale edge. 
Professor Jordan informs me that he now regards L. fallax as simply 
a variety of L. megalotis. I have not had the opportunity to examine 
enough material to enable me to satisfy myself of the correctness of 
this conclusion. He also discards the genus Xenotes.
