EPHIPPIMJ. (Indian spade fishes, ying kung) 



Ephippus orbis (Bloch). 



Color yellowish with round blackish spots, usually larger than 

 eye. The young have a dark ocular band, with the addition 

 of a second dusky band on the shoulders. (6303, 6306, 6316, 

 6322.) 



DREPANID^E. (Spade fishes) 



Drepane punctata (Gmelin). (Ke lung tsang.) 



Drepana punctata Gunther, Cat. Fishes Brit. Mus. (1860), 2, 62; 

 Richardson, Rep. Brit. Assoc. Adv. Sci. for 1845 (1846), 244. 



One specimen. (6277.) 



CH^ETODONTIDJE. (Butterfly fishes) 



Chsetodon aureus Temm. and Schleg. 



Ocular band about equal in width to eye and with a broad 

 yellowish white area in front and back of eye; ventrals yellow; 

 the brownish lines on the rows of scales are almost longitudinal, 

 except on shoulders where they are decidedly oblique ; the caudal 

 has a terminal margin of white and a narrow black line at a 

 short distance from the margin. To this species belong C. 

 collaris Jordan and Fowler 2 and C. aureus Gunther both of which 

 are from Japan. Evidently Richardson suspected that C. aureus 

 Temminck and Schlegel and C. collaris Bloch might be the same, 

 for he says that, "they agree tolerably well," which makes it 

 certain they did not agree fully ; therefore, he was not warranted 

 in uniting them. 



Chsetodon reticulatus Cuvier and Valenciennes is quite distinct 

 from both C. aureus Temminck and Schlegel and C. collaris Bloch, 

 and is characterized by the broad black ocular band, which in 

 most of its length is of much greater width than the eye; the 

 lower portion of the ocular band extends backward to the origin 

 of the ventrals and covers a large part of the thorax ; the ventrals 

 are yellow; the caudal has a very narrow margin of white with 

 2 black intermarginal lines separated by a yellow band ; the base 

 of caudal is jet black. Chsetodon prsetextatus Cantor seems to 

 be a valid species most nearly related to C. collaris of Bloch, 

 being characterized by the dusky ventrals, wide ocular band, 

 and black tip to the opercles; Gunther, who has specimens of 

 both C. prsetextatus and C. collaris, regards them as being 

 different.
