the isthmus; oill rakers few, short and weak; dorsal spines strong-, 

 tlic niickUe the longest and the posterior slender l)ut longcn- than the 

 tirst two; soft dorsal with a blunt angle behind the middle, due to the 

 greater elongation of the rays; first anal spine short, and with the 

 second, which is as long as the third, strong and thick, the third 

 slender; anal fin with an angle behind the middle similar to soft dorsal; 

 pectoral equal to the head, low in the liody; ventral with the first ra}' 

 long and pointed and shorter than the pectorals; caudal truncate, 

 with pointed corners. Lateral line high, arched, and concurrent with 

 the edge of the dorsal fin, descending on the caudal peduncle to the tail. 



Color in spirits pale brown; a broad vertical band through the eye, 

 blackish brown, margined narrowly in front below the e3'e and poste- 

 riorly along its whole length by a broad band of silvery white; ven- 

 tral fins dark brown, the edges and a narrow band near the edges white; 

 caudal broadly edged with white; ventral pale yellow in life; pectorals 

 brown, edged with white; bod}^ on sides with about 18 pale olive lon- 

 gitudinal bands, the width of the pupil of the eye, the upper forking 

 posterioidy. Total length 5|| inches. The above description from a 

 specimen from Ikune, in Satsuma. 



This species is not rare in the warm w^aters about the headlands 

 of southern Japan, from Tokyo southward. We have one example 

 obtained by Professor Mitsukuri at Ikune, in Satsuma. 



Its distribution to the southward is uncertain, as it has l)een confused 

 with a closely related species, Clise.todon prmtextatus Cantor {Tetra- 

 gonopterus or Chsetodon coUarls of Bleeker, Giinther, and Dav), whii^h 

 is probabl}" also Chsetodon retiGulatiiH of Cuvier and Valenciennes. 



In Chxtodon 2)Tcete9'tatus^ of which we have specimens from Formosa, 

 the white stripe before the eye extends upward to the forehead, the 

 dark streaks on the sides are more oblique and do not fork at the ends, 

 and the ventrals are darker. Bloch's figure plainly represents Ch. 

 coNaris, the white stripe before the eye being especially clearly shown. 

 His specimen is said to be from Japan. 



The descriptions of vetiGulatus and inx^textatu^ do not agree very 

 well with our Formosan specimens. Perhaps we have three or more 

 species of the type, perhaps one varying form. In au}" case collar is 

 is the earliest name.
