minute teeth, in the lower jaw a broad band of six rows in front, 

 with fewer rows on the sides posteriorly; the entire body covered 

 to the eyes with large, firm, ctenoid scales; five large scales 

 cover the opercle; the dorsals far apart, the fourth and fifth 

 spines of first dorsal longest, not reaching second dorsal when 

 depressed; the dorsals equal in height, 1.85 to 1.6 in head; the 

 anal a trifle higher than second dorsal but of the same shape, 

 angulate posteriorly, 1.7 to 1.4 in head; the second dorsal and 

 anal are placed forward with a long caudal peduncle, and fall 

 far short of caudal base when depressed; the depth of caudal 

 peduncle twice or more than twice in length of head and 2.4 or 

 2.5 times in its own length ; the caudal nearly truncate, shorter 

 than head, 4 to 4.3 times in length ; the pectoral broadly pointed, 

 longer than caudal and a trifle shorter than head; the ventrals 

 broad, with a deep lobulate frenum, extending nearly or quite 

 to anus, about 1.2 times in head. 



The color in alcohol brown, with four darker brown longitud- 

 inal lines running along the side from head to tail, and inclosing 

 a series of whitish spots separated by fine crosslines; between 

 the two middle longitudinal lines is a series of six dark brown 

 rectangular spots ; five short, dark brown, dorsal crossbars, two 

 before first dorsal, one beneath it, two under second dorsal, and 

 one on top of caudal peduncle; the sides of head marked with 

 spots and bars ; a dark spot at upper posterior angle of opercle, 

 and two small blackish brown spots on base of pectoral and also 

 on base of caudal ; a large, deep black blotch across upper part 

 of first dorsal, the remainder of the fin clear ; the second dorsal 

 diagonally crossbarred by three rows of dark brown spots, the 

 caudal crossbarred by numerous rows- of similar spots ; the anal 

 brown, with a vertical blackish brown bar on each membrane; 

 the pectorals and ventrals unmarked. 



Here described from five specimens, 23.5 to 38 millimeters in 

 length, one, a female, 34.5 millimeters long, nearly ready to 

 spawn. They were obtained by me May 26, 1921, from Titunod 

 River, a mountain torrent at Kolambugan, Lanao Province, Min- 

 danao. 



Tessellatus, in allusion to the beautifully decorated and check- 

 ered sides.
