those on the sides. Teeth: A smgle row, with the four anterior 

 teeth in each jaw enlarged; projedling canines; a canine tooth at 

 the angle of the jaws. The pharjaigeal teeth _L shaped, with one 

 ver}' large tooth in the middle of the cross, flanked on each side 

 by two smaller ones, the anterior limb of the _L with about 12 

 saw-tooth-like teeth. Body oblong, compressed. Fins: The cau- 

 dal is .square; length of its exposed rays on median line equal to 

 longest ra)' of ventrals, 1.66 into head. Height of caudal peduncle 

 2 into head. Longe.st ray of pe(5torals 1.33 into head, the shortest 

 ray 2.50, the base 4. Base of anal 1.66 into base of dorsal. The 

 last ray of dorsal equal in length to la.st ray of anal, 2.50 into head. 

 The spinous portion of dorsal fin not so high as soft portion. Color 

 in spirits: Ground color pearl white with a slight wa.sh of pinkish 

 and yellow. The entire body and opercles covered with black spots, 

 larger than the interspaces; in fact, the ground color, except on the 

 back and belly appears as narrow \'ellowi.sh white reticulations all 

 over the body. These colors, being very sharply defined, give the 

 fish a most striking calico-like appearance. On the back, for a 

 .space about two-thirds the width of e3'e on each side of the dorsal 

 fin the ground color appears without black markings, which gives 

 the appearance of a yellowish band from the snout along the back 

 to caudal fin. This yellowish white of the back is marked b}- about 

 9 .small indi.stinct silvery splotches on each side of the dorsal; the 

 la.st three form short narrow silvery bands over the caudal peduncle; 

 a small silvery line extends down on the snout from the forehead 

 to lips; a pinkish dark-margined stripe half as wide as e3-e from 

 anterior of orbit to maxillary; a silvery stripe of equal width below 

 it from orbit to gape; below this is another pinkish dark-edged .stripe 

 from lower margin of orbit, forming a complete band under chin; a 

 branch of this line encircling a silvery spot on the posterior part of 

 each lower mandible. The remaining markings on sides of head 

 are uniform with markings of the body. Caudal fin yellowish with 

 five dark cross bands. Dorsal with short oblique line alternating 

 with dark lines which fade out on upper part of fin. Anal with 12 

 round black spots edged with silvery white on its inner half; outer 

 half whitish with faded darker spots ; margin of fin blackish. 

 Ventrals with a black spot at base, and two dark cross bands on 

 the ray, the inner one wider and most distinct; outer third of fin 

 yellow. Pectorals 3'ellow. One specimen. Length 4.50 inches.
