DESCRIPTION OF A NEW SPECIES OF AGONIDZ (BRACHYOPSIS 
VERRUCOSUS) FROM THE COAST OF CALIFORNEA. 
By W. N. LOCKINGTON. 
Brachyopsis verrucosus. é 
D. VII-IX, 7-8. A. 10-11. P.14-15. V.1-3. C. 2-10, 2. Lateral 
scutes, 34-36. 
Form elongated, slender, lateral dorsal outline rising very gradually 
from the snout to above the base of the pectoral; central part of the 
upper orbital margin elevated above the line of the forehead and occi- 
put, as is also the tip of the lower jaw and front portion of the snout, 
so that there is a not very conspicuous depression in front of the eye. 
From the highest point the dorsal outline descends gradually to the 
elongated and narrow caudal peduncle. 
Abdominal outline from posterior extremity of mandible to- caudal 
peduncle straight. 
Greatest height about 11; greatest width 7-74; length of head 43-414 
times in total length to tip of caudal (mouth closed); greatest depth 
about 14 in greatest width; depth of caudal peduncle about 3? times in 
the greatest depth. 
Mouth oblique, the lower jaw projecting considerably beyond the 
upper, its tip entering into the dorsal outline, and its posterior extremity 
reaching to a vertical from the anterior margin of the pupil. 
Mandible half or nearly half the length of the head. 
Maxillary short, broad posteriorly, and set at a more oblique angle 
than the mandible, below which the lower angle of its posterior margin 
projects when the mouth is closed, while the entire length of its upper 
margin is hidden beneath the preorbital in the closed mouth; a short 
and slender barbel at its posterior extremity. 
Kntire length of upper jaw less than 4 that of head. 
Teeth uniform in both jaws, villiform, very small, in a band which is 
widest in front, but divided in the center. 
A patch of similar but even finer teeth (perceptible to the touch, but 
scarcely to the eye) on vomer, and another on each palatine. 
Eyes directed laterally and somewhat upwards, oval, their longi- 
tudinal diameter a little less than the length of the snout, and about 
45-45 in the length of the side of the head; interorbital area sunken, 
its width about 5 times in the length of the head. 
Snout a little longer than the longitudinal diameter of the eye; two 
short backward-directed spines on its summit, slightly posterior to the 
line of the tubes of the nostrils. 
Preorbital large, with several small spines on its lower margin. 
Supraorbital margin set with small spines, and rising in its posterior 
portion to a spinulose crest.
