DESCRIPTIONS OF NEW AND LITTLE-KNOWN FISHES. 
127 
but slightly longer than longest anal rays; anterior dorsal and anal rays longest; pectoral 1!, in head; 
ventral s reaching origin of anal; caudal deeply notched, the lobes long and pointed. Scales large, 
lateral line incomplete, developed only on 6 to 10 scales. Back olivaceous ; side with a broad black 
band extending from snout through eye, and ending in a rather distinct black spot on base of caudal, 
the black spot in some specimens (probably mature males) surrounded by orange; the black line 
bordered above by a narrow orange or reddish line, less distinct, or even whitish, in females and 
immature individuals ; under parts plain ; fins all plain; dorsal and caudal somewhat dusky; dusky 
specks on body along base of anal and under side of caudal peduncle; lower jaw tipped with dusky. 
This species resembles Notropis anogenus, but differs in having the mouth somewhat larger and less 
oblique, the lower jaw more included, the body more slender, the lateral line less developed, the dorsal 
fin more posterior, and the anal rays more numerous. It was found in considerable abundance in 
the St. Johns River near Welaka, Florida. 
Etymology, welaka, from the type locality. 
4. Alosa alabamae Jordan & Evermann. Alabama Shad. (PI. 7, fig. 5, male, and fig. 6, female.) 
Alosa alabavice Jordan & Evermann, in Evermann, Rept. U. S. F.- C. 1895 (December 28, 1896), 
203-205. 
Since the publication of the original description of this species some additional information has 
been obtained regarding the occurrence of shad in the streams tributary to the Gulf of Mexico. 
During the season of 1897 the run of shad in the Black Warrior River at Tuscaloosa seems to 
have been unimportant. During the investigations in the South in April, 1897, some testimony was 
obtained indicating that there is usually each year a large run of shad at Mobile. That the fish is 
not taken there in large numbers is due, it is claimed, to the fact that suitable apparatus is not used. 
Some inquiries made at Montgomery failed to elicit any definite information concerning the 
occurrence of shad in the Alabama River at that place. The same inquiries made at the mouth of 
Pearl River and at different places along the Atchafalaya, Sabine, and Neches rivers yielded similar 
results. No one of those interviewed had ever seen real shad in any of these rivers. The Atchafalaya 
fishermen use for bait on their set-lines what they call shad, but they are Dorosoma, Signalosa, and 
Hiodon. “Shad” have been from time to time reported from the larger rivers of Arkansas; also from 
the Ohio and the Great Kanawha; but whether they are Alosa alabamce or some other species has not 
been determined. 
SIGNALOSA, new genus of Clupeidw, allied to Alosa and Dorosoma. 
Type : Signalosa atchafalaya; Evermann & Kendall. 
Body short, deep, and compressed, the form somewhat elliptical ; ventral outline more strougly 
curved than the dorsal; head rather large, snout sharp and pointed, not tumid; mouth small, oblique, 
the lower jaw scarcely included; maxillary of three pieces, broad and. curved, but without notch in 
the outer margin as in Dorosoma; caudal peduncle short and deep. Branchiostegals 5; pseudo- 
branchise large ; gillrakers short and very numerous, about 340 in number. No teeth; adipose eyelid 
present; stomach gizzard-like; scutes about 6+10. Last ray of dorsal very long and filamentous. 
This genus is allied to Dorosoma, from which it is plainly distinguished by the absence of the 
notch in the maxillary, the more pointed snout, the less-included lower jaw, the shorter anal fin, larger 
scales, and the fewer scutes. It differs from Alosa in the very numerous gillrakers, the character of 
the dorsal fin, and in other respects. 
Etymology, signum, a flagstaff or pole; Alosa, the shad; a reference to the long dorsal ray. 
5. Signalosa atchafalayae, new species. (PI. 7, fig. 4.) 
Type locality, Atchafalaya River at Melville, Louisiana. Type, No. 48790, U. S. N. M. Cotypes,

Length of type, 4| inches to base of caudal, or 5f inches to tips of caudal rays. 
Head 3f ; depth 3*-; eye 3£ in head; snout 5i; maxillary 3) ; D. i, 12; A. i, 24; scales 42-15; 
scutes 17+10. Body oblong-elliptical, compressed, the hack in front of dorsal narrow; ventral edo-e 
sharp, serrate;, head small, mouth terminal, oblique, lower jaw slightly included; snout rather pointed, 
not blunt, as in Dorosoma cepedianum ; maxillary in 3 pieces, long and curved, reaching vertical at 
front of pupil, the outer edge not notched; no teeth. Caudal peduncle short, compressed, and deep. 
Origin of dorsal fin over base of ventrals, much nearer tip of snout than base of caudal, the last ray
