18. Notemigonus chrysoleucus (Mitch.). 
Numerous specimens of this widely distributed minnow were taken at each of the 
following places: Neches River, 14 miles east of Palestine; Long Lake and Trinity 
River, near Palestine; Sims Bayou, Kilper’s Ponds, and Big White Oak Bayou, at 
Houston; and Dickinson Bayou, near Dickinson. 
19. Cyprinodon variegatus (LacApecIe). 
Thirty specimens of this species were obtained at Galveston, 3 from Dickinson 
Bayou, and 10 from Corpus Christi. It is abundant both at Galveston and Corpus 
Christi. This is the form described by Baird and Girard as C. gibbosus , but our speci- 
mens do not seem to differ materially from northern ones. 
In our study of this and related species we had occasion to compare specimens of 
Cyprinodon carpio Gunther and C. mydrus Goode & Bean, and can not see any tangi- 
ble differences. 
20. Fundulus similis (B. & G.). 
The collection contains 14 specimens from Galveston and 2 from Corpus Christi. 
It is an abundant species at each place. 
21. Fundulus heteroclitus (L.). 
A dozen specimens from Corpus Christi, 2 from Dickinson Bayou, and 14 from 
Galveston, at each of which places it is abundant. 
22. Fundulus pallidus, sp. uov. (PL xxxv.) 
One specimen, If inches in total length, taken in Galveston Bay, near Swan Lake, 
Texas, November 10, 1891. Head, 3f ; depth, 4; eye, 3£; D. 12; A. 11; scales, 31-11, 
about 10 before the dorsal. 
Body, stout; head, heavy; caudal peduncle long and much compressed; snout, 
short and blunt, shorter than eye, which is two-thirds the width of the interorbital 
space; humeral scale not enlarged, two rows of scales on the cheek; mouth rather 
small, little oblique, teeth pointed, in more than one series, the outer enlarged. Dorsal 
fin over the anal, its origin midway between base of caudal and posterior edge of 
opercle, or midway of total length, its ray short, about If in head; anal rays about 
equal in length to those of dorsal. 
Scales medium, not firmly attached, 31 in longitudinal series, 11 in transverse from 
dorsal to anal, about 10 before the dorsal. 
Color, pale yellowish; sides with about 13 narrow, dark, vertical bars, much nar- 
rower than the pale interspaces, not extending on the back or belly; scales sparsely 
covered with fine dark punctulations, few on the vertical fins and head; a large oblong 
black spot on the back immediately in front of dorsal fin. 
This species is allied to Fundulus similis Baird and Girard, but the head is less 
pointed, the snout very much shorter, it being shorter than the eye, while in F. similis 
it is 14 times the eye, the dorsal has one more ray and the anal two or three more, the 
color is paler, the bars less distinct, there is no dark dorsal line as in the other, while 
the pronounced black spot in front of the dorsal is not found on F. similis.
