» The other (Icon. Reeves, 250; Hardw. 104) resembles Up. bilineatus of Quoy and Gai- 
mard, in having two longitudinal streaks, but differs in its more oblique profile and greater 
number of fin-rays. Both these and the rest of the species figured by Mr. Reeves, were pro- 
cured at Canton.

Mr. Reeves has deposited the specimen from which his figure was drawn in the British 
Museum. It has the form of 4p. trimaculatus, but scarcely any traces are discernible of the 
three black dorsal spots, and the figure wants these spots entirely, having a bronzed umber 
colour on the back, with pale sides. The pectoral is orange, and the other fins brownish- 
purple, all without spots. The Chinese fish has a great similarity to 4p. rex-mullorum, but 
its body is a little higher. The spine of the second dorsal is strong. The preoperculum is 
serrated nearly all round, and the villiform bands of teeth on the jaws are shorter and finer 
than those of 4p. rex-mullorum.

A Canton specimen of this fish, collected by the Rev. George Vachell, belongs to the Cam- 
bridge Philosophical Institution, which differs from the three noticed in the ‘ Histoire des 
Poissons,’ that have no more than nine soft rays in the second dorsal, in having four teeth re- 
clining backwards on the hinder part of the orbit. Scaly nape, convexly coped with an acute 
mesialline ; the scales coming to a point between the posterior parts of the orbits. | Gill-cover 
entire and scaly, a single row of large ones on the inter-operculum, which is also entire. Two 
acute edges of the lower limb of preoperculum beautifully serrated, and the posterior edge of 
the upper limb rather openly and slenderly toothed. The corner is rounded, and the fore- 
edge of the upper limb is vertical and smooth. Whole edge of the preorbitar spinously toothed. 
Eye large; lower jaw ascending. 
A recumbent, concealed pre-dorsal spine. The spines of the dorsal are curiously beaded, 
as if jointed; and the ventral spine also is torulose. The lateral line, composed of about thirty 
scales, is arched anteriorly in a brown band, which descends from the first dorsal, and is there 
diffracted and resumed two scales’ breadth lower, whence it is continued in a silvery stripe to 
the tail. Length of fish, 2°50 inches. Height of body, 1-68 inch.
