its length. Head bioad iuid Hat above. luterorbital space in tbe 

 head 2^ times. Eye in head .'U to 4, overhung slightly by the supra- 

 orbitals. Snout obtuse, equal to the eye. Cheeks nearly perpendic- 

 ular, so that the head i« not narrowed below as in some species of 

 Zygonectes. Mouth small, rather oblique, the lower jaw heavy and pro- 

 jecting beyond the upper. Teeth in a broad baud in each jaw, the outer 

 enlarged. First ray of dorsal jdaced directly over, or slightly behind, 

 the first of anal. Distance from first ray of dorsal to insertion of the 

 <iaudal falling behind the edge of the operculum. Both dorsal and anal 

 larger in male than female. The posterior rays of anal of male the 

 longest. Pectorals of males reaching the base of the veutrals. Ventral 

 tips reaching the vent. Both shorter in the females. Caudal broad 

 and fan shaped. Color dark olive, paler below from lower jaw to cau- 

 dal. Males with about 12 or 14 distinct transverse stripes, which are 

 narrower than the interspaces. These occupy the whole side from the 

 base of the caudal to the insertion of the pectorals, but are most distinct 

 posteriorly. In fresh specimens each scale has in its center an orange 

 or bronzy spot. Along the sides these form distinct longiludiual rows. 

 In the females the transverse bands are indistinct on the anterior half 

 of the body, but distinct posteriorly. All the scales have black edges 

 which give the fish a cross-hatched appearance! Sides of the female, 

 also, with numerous spots of bronze and a rather conspicuous row of 

 dark spots along the place of the lateial line. The vertical fins all with 

 dusky tips; otherwise plain. 



Eight specimens obtained at Westville. Length of longest male 1^ 

 inches ; of longest female nearly 2 inches. 



7. Sygonectes nottii, Agassiz. 



In the American Journal of Science and Arts for 1854, on page 353, 

 Prof. L. Agassiz described in a brief manner several species of Zygo- 

 nectes, among which is Z. nottii. I quote so much of his language as is 

 applicable to this species. 



" The species of the genus Zygonectes may be arranged in two groups: 

 1, those in which there are several more or less distinctly dotted lines 

 along the sides of the body and in which a broad black band extends 

 across the eye and rheek. To this group belong: Z. nottii, Agass. The 

 darker longitudinal lines alternate with fainter interrupted ones. Males 

 with distinct transverse bands. Dark olive above, fading upon the sides, 

 silvery below. Operculum, throat, and space in advance of the eye light 

 orange color. Mobile, Ala. Collected there with Dr. Nott. Missis- 

 sippi : Colonel Deas. — Z. lineoJutus Agass. Longitudinal lines broader 

 and undulated or serrated, the transverse bands of the male very dis- 

 tinct and broader than the longitudinal ones; olive colored, darker 

 along the back and fading upon the sides, lower jJarts silvery. Dis- 

 covered by Dr. W. I. Burnett at Augusta, Ga."
