anterior rays of the anal are spinous or articulate can not be determined, but they are probably 
spinous. No distinctive color markings are apparent. 
This species is represented by 2 small specimens, each about 7.5 inches long, in a very bad state 
of preservation, the scales having all been lost and the tins broken. The specimens were collected at 
Honolulu by Mr. E. L. Berndt, to whom we are indebted for them. Type, No. 51400, U. S. N. M.

Genus 123. SYNAGROPS Gunther. 
Body rather elongate, covered with rather large, cycloid, deciduous scales, about 35 in lateral line; 
scales of head covered with very small scales; eyes large; jaws with a band of villiform teeth and with 
strong canines in front; small or villiform teeth on vomer and palatines; preopercle with its angle pro- 
duced and with soft serrations; dorsal rays ix-i, 10; anal ii, 7; vent normal. Coloration black. 
One species known from deep water in Japan and one from the Hawaiian Islands.

Head 2.88; depth 3.75; D. xi-i, 9; A. ii, 7; P. 14 or 15; V. i, 5; lateral line 28 to 29 (-)- 2 or 3 on 
tail); 2 scales in a transverse series between lateral line and origin of first, doTsal fin; width of body at 
base of pectorals nearly 2 in the depth; least depth of caudal peduncle 2.25 in greatest depth of body; 
greatest width of head 1.5 in the greatest depth; orbit 3 to 3.25 in head; maxillary 2.25; ventral spine 
2.5; snout 1.3 in orbit; distance from tip of snout to origin of first dorsal 2.67 in body; from tip of 
snout to origin of anal a little more than 1.5; from root of ventrals to origin of anal 3.13; base of first 
dorsal 5.5; base of second dorsal 8.3; distance between dorsals 10; base of anal 9. 
Body elongate, compressed; head compressed, dorsal and ventral profiles convex, similar; tip of 
snout about on a level with lower margin of pupil; orbit large; jaws equal, or the lower very slightly 
projecting, entering the steep profile; maxillary with a ridge along the middle, reaching to or a little 
beyond center of eye, much expanded behind, the end emarginate, lower posterior angle somewhat 
enlarged into a lobe; small teeth in bands on jaws, vomer, ahd palatines; a large canine tooth inside 
of band of small teeth near anterior end of each premaxillary, tip of lower jaw fitting between 
them; each ramus of lower jaw with 9 canine teeth in a single series, 2 very close together at each 
side of tip of lower jaw, just outside of these a depression in jaw into which fits canine of upper jaw, 
and behind this 7 nearly equidistant teeth, of which the most anterior is smallest and the fourth the 
largest, or as large as those behind it; small teeth outside of the row of canines, very few in number
