years and -who has a remarkably wide and accurate knowledge 
of the fishes of the region. The writer is greatly indebted to 
him for many favors. To the United States Bureau of ."Fish¬ 
eries, and especially to Dr. W. B. Evermann, he also owes 
much, and Dr. Meek of the Field Museum kindly named some 
of the forms and corroborated the determinations of a few 
others. 
The material comes mainly from three sources: First, an 
eighteen hundred foot seine of six inch mesh, and about twenty 
feet in depth, hauled twice a day, during my stay, by Mr. 
Schneli and his crew. Secondly, a Baird seine, seventy-five 
feet in length, sometimes hauled separately, but more frequently 
attached behind the large seine when this had been spread 
eight or nine hundred feet from shore. In this manner we 
obtained several forms which w T ould otherwise have been missed. 
Lastly, a thirty foot minnow seine was hauled a number of 
times daily along shore at various places in the neighborhood 
of Best Island, the high shore just north of Central Point 
(see Chart Ho. 184, Mississippi Biver Commission). The 
number of hauls made by all these seines gives some reason for 
believing that we saw practically all the species occurring with 
any frequency in the lake. A few more species would prob¬ 
ably be found by examining the muddy upper end of the lake. 
In the enumeration below, I have followed, without devia¬ 
tion, the nomenclature of Jordan and Evermann’s “Manual.” 
The common names, when given, are those used by the fisher¬ 
men of the region. 
1. Ichtiiyomyzon concolor. Tamper Eel. This is an ex¬ 
tremely common form here. It attacks the catfishes, and in 
much lesser degree the buffaloes and suckers, but its favorite 
host is Polyodon. Among about fifteen hundred spoonbills 
examined, there were but few that did not show some signs 
of lamprey bites. A number of times I have taken from ten 
to twenty-five lampreys from one specimen, although they 
usually desert their host when brought into very shallow water. 
They attack all parts of the host, most frequently however the 
belly. Occasionally one was found to have worked its way 
under the gular membrane and to have attached itself to the
