23. Fundulus xenicus Jordan and Gilbert. 
Fundulus xenicus Jordan and Gilbert, Proc. U. S. N. M. 1882, 255 (Pensacola) ; Synopsis, 1882.892. 
Adinia multifasciata Girard, Proc. Acad. Nat. Sci. Phila. 1859, 117. 
Four specimens of tliis interesting little species were taken, in Galveston Bay. 
Head, 3; depth, 2£; eye, 3; snout, 3; D. 12; A. 12. 
Body greatly compressed, the hack elevated, profile from snout to dorsal nearly 
straight, this forming an acute angle with the ventral line from snout to anal fin; 
caudal peduncle very deep, its greatest depth V y in head ; dorsal large, its origin in 
front of anal, the longest rays nearly as long as head. The dusky blotch said to be 
below and behind the eye is not evident. 
24. Zygonectes funduloides, sp. nov. (PI. xxxv.) 
This species is described from two specimens, each 14 inches long, from Dickinson 
Bayou, Dickinson, Texas, November 13, 1891. Head, 3£; depth, 4J; eye, 3f ; D. 9 or 
10; A. 9; scales, 35-11, 24 before the dorsal. 
Body moderately robust, width at pectorals a little greater than greatest depth of 
Lead; snout rather blunt, equal to eye; interorbital width 1§ times diameter of eye; 
caudal peduncle deep and compressed; mouth not large nor greatly oblique; teeth 
pointed, the outer series being somewhat enlarged ; peritoneum pale. General color in 
spirits, dark olivaceous, sides with 10 to 14 dark vertical bars which are usually two 
to three times as wide as the intervening silvery ones; in one specimen the bars ex- 
tending from the dorsal to the anal are about equal in width to the silvery interspaces; 
whole body, including all the fins, profusely dusted over with minute brownish spots 
which are very numerous on back and top of head; a narrow, dark line extending from 
nape to origin of dorsal. 
Dorsal fin small, slightly in front of anal, its origin midway between posterior 
edge of opercle and base of caudal fin, the longest rays about equal to base of fin, or 
half length of head. 
If the characters which are used to distinguish the genus Fundulus from Zygonectes 
are really of generic value, the small size of the dorsal fin would put this species in 
Zygonectes , though the position of the fin is rather that of Fundulus. I have compared 
these specimens with numerous young individuals of F. heteroclitus collected by Dr. 
H. M. Smith at St. George Island, Maryland, and find them very similar in general 
appearance; in Z. funduloides , however, the dorsal is placed further back, and has 
fewer rays (9 or 10 instead of 12), the anal is smaller (9 instead of 11); the pattern or 
coloration is the same, but the contrasts are more marked, and instead of the dark 
dorsal band found in this species the young of F. heteroclitus have a small dusky area 
at base of dorsal in front; the young have an ocellus upon last rays of dorsal, which 
is not found in the other species. 
25. Zygonectes pulvereus, sp. nov. (PI. xxxvi.) 
This species is based upon the following specimens : 
Nine specimens, If to 2 inches long, from Dickinson Bayou, Dickinson, Texas, 
November 13 and 14, 1891. 
One specimen, 1£ inches long, from Buffalo Bayou, Houston, Texas, November 1G, 
1891. 
One specimen, 14 inches long, from the mouth of Oso Creek, Corpus Christi, 
Texas, November 28, 1891.
