one-fourth of it. The diameter of the eye equals the width of the 
interorbital space, is one-fourth of the length of the head, and two- 
thirds of that of the snout. The preorbital is longer than high, and 
higher than the orbit. There are six series of rather narrow scales 
between the preorbital and the angle of the preeoperculum. Molar 
teeth in two series,—those of the outer series being conical, pointed, 
and much larger than those of the inner series. The third, fourth, 
and fifth dorsal spines are produced, flexible (in immature specimens) ; 
the second and third anal spines of nearly equal length and strength, 
one-third of the length of the head. The pectoral extends on to the 
vertical from the first soft anal ray, and its length is contained three 
and a half times in the total; the ventral reaches to the anal fin. 
Silvery, with red, shining golden stripes along the series of scales ; 
a dark-claret spot on the back beneath the fifth, sixth, seventh, and 
eighth dorsal rays, extending on the membrane of the fin ; a smaller 
spot on the upper part of the axil ; the spinous dorsal, caudal, anal, 
and ventral fins with the margin blackish. 
Length 9} inches. 
Hab, Sea of Lisbon, 
This fish forms a new addition to the European fauna. It has 
been sent to the British Museum by the Rey. R. T. Lowe in a fine 
collection of fishes made at Lisbon. He proposes to call it after 
Dr. Bocage, of the Lisbon Museum, in case it should prove to be a 
new form, and writes:—‘ It grows very large; I saw one which 
was 2 feet 10 inches long, and was said to weigh more than 16 lbs. 
Its head was bright red or vermilion. The elongate dorsal spines are 
only a conspicuous character in young examples.”

The animal appears in all respects to resemble that of the Estheria 
gigas, except that the eye is placed on a more prominent pedicle. 
The specimen examined was a female, and full of ova. These were 
disposed all along the body of the parent, were very numerous, and 
presented a very pretty appearance when seen under the microscope. 
They are small, round, and grooved, the grooves running in a cir- 
cular manner like those of a rifle. 
The shell or carapace is of a greenish colour, of an oval shape, 
and flattened. The umbo is anterior, situated about 2 lines from 
the margin. The dorsal margin slopes slightly downwards, and is 
dentated on the edge, in consequence of the ridges, with which its 
surface is strongly marked, terminating at the external edge in a 
prolongation or tooth. The ventral margin of the carapace is rounded
