Gilbert, iu tlieir Sjmopsis of the Fishes of Xorth America, say: "Pro- 

 fesssor Agassiz (Amer. Jour. Sci. Arts, 1854, 353) ineutions three more 

 species of this genus, which have not since been recognized, besides two 

 {Z. lateralis and Z. zonatns) which are evidently identical with Z. notatm, 

 and anotlier, Z. lincolatus, which Professor Putnam informs us is identi- 

 cal with Z. nottii.''^ 



Among the fishes collected at Westville, Holmes County, Florida, 

 there are two specimens of a Zygonectes that agree so well with Professor 

 Agasslz's description of Z. nottii that I have no hesitation in assigning 

 them to that species. I proceed to give a detailed description of th(^ 

 more characteristic specimen in my possession. 



Length of largest specimen, apparently a male, 1^^ inches to base of 

 caudal. Head in length 3| ; depth in U ; dorsal 7 or 8; anal 9 or 10;^ 

 scales 36-10. Form of body much like Z. dispar Ag., compressed be- 

 hind ; head broad and somewhat concave above, narrow below ; inter- 

 orbital space fully one-half the length of the head, 1-^ the diameter 

 of the eye; snout obtuse, shorter than the eye; outer row of teeth, 

 above and below, enlarged and recurved ; eye large, its diameter in the 

 bead 2| times. 



Pectoral fin two-thirds the length of the head; ventrals slightly 

 shorter, attaining the vent; dorsal and anal low, little higher than one- 

 half the length of the head. First ray of dorsal situated slightly be- 

 hind the first anal ray, and over about the 17th scale in the longitudi- 

 nal series. The distance from the snout to the first dorsal ray passing 

 beyond the tips of the caudal rays. The distance from the first dorsal 

 ray to the base of the caudal reaching forward to the insertion of the 

 pectoral. 



Color. — Belly and ground color on lower half of body silvery. Sides 

 with six narrow longitudinal black stripes running from the head to the 

 tail. These stripes a little narrower than the interspaces and perfectly 

 distinct even on the caudal peduncle, the upper stripe rather faint and 

 succeeded higher up by one or two other obsolete stripes. The inter- 

 spaces of the stripes are occupied, especially above, each by a row of 

 black dots forming the fainter interrupted stripes of Professor Agassiz's 

 description. On the back these rows of dots are rather more distinct 

 than the continuous stripes. There is a median dorsal stripe ; about 

 10 transverse bars of the width of the longitudinal stripe, but fainter, 

 and placed about two scales width apart, occupy the posterior h;ilf of 

 the body. Lower surface of caud<il peduncle dotted with black, a 

 black streak behind tlie edge of the opercle. Upper surface of the head 

 dusky and also the snout and tip of lower jaw. A broad black mask 

 covering the eyes and extending downward over the cheeks; upper half 

 of the operculum, the space in front of the eye and most of the lower 

 jaw, orange red ; lower half of the operculum and anterior half of breast 

 yellowish orange.
