Characteristics. Body much compressed, suborbicular ; olive green on the sides above ; with 
metallic reflections beneath. Seven free spines before the dorsal, and 
three before the anal. Length three inches. 
Description. Body exceedingly compressed ; its height to its length as one to one and a 
half. Thickness, 0°5. Body scaleless. The lateral line moderately incurved upward, and 
thence straight to the tail, not concurrent with the back. Facial line broadly concave ; the 
head projecting forward, with a blunt snout. Eyes large and silvery. Lower jaw closes 
within the upper; both with scarcely perceptible teeth. Branchial rays seven. Pectorals 
acuminate. Caudal deeply forked. Ventral rays are stated to be four, but they are probably 
of the normal number.

This species was captured in the harbor of New-York, September, 1817, and is to be 
considered as an occasional visitor only from the south. Cuvier and Valenciennes, with refe- 
rence merely to the plate, and not being acquainted with the text, suppose that it may pos- 
sibly be their Trachinote brun. Their language is, ‘‘'The Spinous Dory represented by 
“¢ Mitchill (pl. 6, fig. 10) appears to resemble in its form very much our T. fuscus ; but as he 
‘does not speak of it in his text, we cannot confirm this resemblance by a comparison of 
“the number of rays and other circumstances which could only be explained by a verbal 
“description.” The 7. fuscus of Cuvier and Valenciennes is 8°0 long, brown, with conspi- 
cuous teeth; the anterior elongated rays of the dorsal and anal reach to the end of their 
respective fins. It is evident, from these circumstances, that our species is distinct ; and 
finding none other approaching it, I have retained the name proposed by its original describer.
