interorbital space equals one-half the length of second dorsai base. The 
distance between the spiracles equals 4 times their greatest length. 
The first dorsal is very long and low, highest behind its middle, the 
length of its base equal to 7 times its greatest height; its distance 
from the snout is a little more than twice the greatest length of pecto- 
ral. The second dorsal is distant from the end of the first a length 
equal to nearly twice its greatest height; the length of its base is some- 
what more than the body height at origin of first dorsal. 
The second dorsal begins at a distance from the end of the first, which 
is equal to the height of body at ventral origin; the length of its base 
equals twice the interorbital distance; its height equals nearly twice 
the length of the orbit. 
The anal is entirely under the second dorsal, but its base is a little 
less than five-sevenths as long as that of the latter; the greatest height 
of the anal equals the least height of caudal peduncle. 
The caudal originates at a distance from the end of the second dorsal 
about equal to the height of the anal; it is divided by a notch into a 
short upper portion, whose length is very little more than the greatest 
height of first dorsal, and a very low and long lower portion, the long- 
est margin of which is nearly twice as long as the snout. The distance 
of the caudal from the end of anal base equals one-fourth the length of 
second dorsal base. 
The distance of pectoral from snout is contained 5 times in total 
length; the length of pectoral equals nearly twice the width of its base, 
and is a little more than one-ninth of total length. The greatest width 
of pectoral equals twice the height of anal, and is contained twelve and 
one-third times in total length. 
The origin of the ventral is slightly in advance of the end of first dor- 
sal, and is behind the middle of total length a distance equal to the in- 
terorbital space. The length of ventral equals that of lower jaw. The 
width of ventral base equals that of pectoral base; the greatest width 
of ventral slightly exceeds its length. 
Color.—When received the margins of the fins were apparently faded; 
the original color was probably grayish-brown with dark margins on 
all the fins except the first dorsal. Capello states that his example was 
chestnut-brown. 
Remarks.—The gills and mouth were obstructed by sand. The only 
parasites discovered on the animal were a couple of isopods, one of 
which was found in the eye cavity.
