and third spines subequal, the second slightly stronger than the 

 third; ventrals 1.14, short, tips not reaching vent; pectorals 1.10. 



Color in alcohol: Silvery, tinged with a very pale lemon yellow; 

 a narrow black saddle across upper part of interorbital, not reach- 

 ing eye; a small black area on upper part of eye and adjacent 

 interorbital region; an irregular black saddle from in front of origin 

 of dorsal downward across upper part of opercle, duskiness extend- 

 ing across upper part of preopercle to posterior margin of eye; 

 a black area crossing fifth to ninth dorsal spines and extending 

 downward to middle of side; a broad black band including last 

 dorsal spine and anterior third of soft dorsal extending downward 

 and backward across base of soft dorsal, caudal peduncle and 

 posterior third of anal; margin of soft dorsal silvery white, the tips 

 of the rays very narrowly edged with black, a narrow inframarginal 

 black line below marginal band, area between this and broad black 

 band crossing base of fin dusky white; a blackish segment on tips 

 of middle caudal rays; anterior to this a similar white band preceded 

 by a black crescent fading out on base of fin; anterior two-thirds of 

 anal silvery white, posterior third, black; membranes of spines and 

 tips of anterior rays black; dusky or blackish lines extending down- 

 ward and backward and upward and backward along the rows of 

 scales, forming a checker board appearance and emphasizing scale 

 arrangement. 



This species resembles C. xantkurus but differs markedly in colora- 

 tion, in number of dorsal spines, in smaller scales, and in having the 

 rows that extend downward and backward more nearly horizontal. 



Type.— Cat. No. 67353, U.S.N.M., 9.6 cm. in length, from Agojo 

 Point, Catanduanes Islands, Pacific coast of Southern Luzon, Philip- 

 pine Islands. 



Another example 8.5 cm. in length was taken at Port San Pio V, 

 Camaguin Island, north of Luzon. This individual differs slightly in 

 coloration from the type; the black markings on body are more pro- 

 nounced, the black saddle across interorbital is interrupted on the 

 right side, and the black and white markings of caudal are more dis- 

 tinct. Color in life: No yellow; pale parts silvery, darker parts 

 black.
