Species nova. 
This fish is very easily distinguished by its very small head, with conic 
muzzle, and elevated arched back, combined with a small size, and other 
characters. 
The head enters the length not less than five times, and is much arched 
in transverse section posteriorly above. The diameter of the eye is large, 
entering the head between three and four times; the muzzle is regularly 
conic, and projects far beyond the mouth. The latter is remarkable for 
its small size, and lack of projectility ; in ordinary individuals it would 
about admit a pea. The upper lip is not pendent below the front of the 
muzzle. The shape is broadly fusiform, the dorsal line rising to the fin. 
It is, nevertheless, more compressed than the species already described. D. 
XIV constantly. 
The ground color is silvery, the scales shaded with leaden above, and 
with black pigment at their bases, giving a dusky hue to the whole, as is 
not seen in the species already described, except the P. pappillosus. Belly 
and inferior fins pure white, lacking the red and orange of many others. 
This fish never exceeds a foot in length, and is very abundant in the 
Catawba and Yadkin Rivers. It is caught with the preceding two species 
and is used for food, but is the least valued of all the species. It is called 
at Morganton, ‘‘ blue mullet.’’

Spec. nov. 
This large species has the small head of the last, without the small 
mouth and many of its other peculiarities. The head enters the length not 
less than five times; muzzle is prominent, but the mouth is less inferior 
than in Pt. coregonus. The eye, in aspecimen sixteen inches long, is 
relatively larger than in P. collapsus, and about as in Pt. coregonus. The 
muzzle is less prominent than in the last named fish, but more so than in 
Pt. collapsus. The mouth is of ordinary size, but the upper lip does not 
form a free projecting rim as in the latter. The under lip is a narrow 
crescent following the boundary of the mandible, not folding so as to meet 
on the middle line as in the species already described. 
Dorsal outline a little elevated, rays XIV. 
Colors very light ; the inferior fins white. In size this species is one of the 
largest, reaching four pounds and over. It is much.valued by the people 
living in the neighborhood of the Catawba River, North Carolina, as an 
article of food. They call it the ‘‘White Mullet.’? I have not seen it in 
the Yadkin or any other river.
