ANNOTATED LIST OF FISHES 



129 



Color. — In alcohol, plain grayish green above and silvery below. Fins all pale, the dorsal, 

 caudal, and anal with dusky punctulations, these most numerous distally on caudal. 



Variability. — The specimens, being of nearly uniform size, vary little among themselves. 

 The dorsal spines in the nine specimens at hand vary from 7 to 9 — that is, six have 7 spines, two 

 have 8, and one has 9 spines. The anal fin has 6 spines in eight specimens and 7 in the other. 

 In color they vary in the number of dusky punctulations present on the vertical fins, some of the 

 paratypes having the fins much darker than the type. The dark color, however, is not arranged 

 in spots, as in sparoides, resembling annularis in this respect. Some of the paratypes have indica- 

 tions of pale spots on the caudal fin. Such spots are quite numerous and distinct on the caudal 

 in specimens of about the same size in the related species and often are present, also, on the dorsal 

 and anal fins. 



Holotype. — No. 88381, United States National Museum, standard length 107, total length 

 142 millimeters; borrow pit near Money, August 14, 1925.

Paratypes. — Eight specimens from the type locality, all taken with the holotype. 



The species is named for Dr. M. A. Barber, of the United States Public Health Service, who 

 was engaged at Greenwood, Miss., in researches pertaining to malaria during the period when the 

 present collection was made. Doctor Barber allowed the authors the free use of his laboratory 

 and rendered other valuable aid. 



This fish was found only in a borrow pit near Money in association with the black crappie, 

 the white crappie being absent in this pond. This borrow pit had a length of about 200 feet, a 

 width of about 30 feet, and the greatest depth of the water when the collection was made was 

 about 5 feet. This pond, owing to its steep banks, the grayish clay soil, wave action, and the 

 almost total absence of vegetation, was distinctly muddy. The golden shiner (Notemigonus cryso- 

 leucas) was the only other species present. 



Four specimens of this species examined for food had fed mainly on copepods, ostracods, 

 and some insects (principally back swimmers) . The other species of crappie, when they had 

 attained a length as great as the specimens of this form that were examined, usually had changed 

 definitely to a fish and large insect diet, and the small crustaceans were ignored. Due to the 

 scarcity of other foods, the fish probably continued to feed on the usual diet of the young. In 

 obtaining this small food, they doubtless were aided by the long gill rakers and probably also by 

 the very large eye. In eight specimens of the size of the black crappie, from the same body of
