58 PROCEEDINGS OF THE ACADEMY OF [1897. 



Carassius auratus Linnajus. Giinther, Cat. IV, 32. 



Recorded by Sauvage. 



Labeo decorus Peters. 



Labeo decorus Peters, Monatsbericht der Konigl. Akademie der Wiss. Berl., 

 Dec, 1880, p. 1031. 



Two specimens, 4J and 6 inches long. 



Head 4} ; depth 2>\ ; eye 3 ; scales 8 or 9-38-5. D. 15 ; A. 7 ; P. 

 17 ; teeth 5, 4, 2-2, 4, 5. 



Dorsal and ventral profiles about equally arched, not concave 

 above eyes. Snout blunt, little projecting, three folds to upper lip, an 

 outer simple membrane, an inner one, soft, cartilaginous covered with 

 a horny substance, between them a fringed fold. Lower lip with a 

 horny-covered fold, which is continuous with the fringed fold of the 

 upper lip ; outside of this the lip is full and finely papillose. Diam- 

 eter of eye equals width of mouth, equals snout, and is 1^ in inter- 

 orbital space. Rostral barbel longer than and reaching the base of 

 the maxillary barbel, a pore at its base. Pharyngeal bones small ; 

 the teeth set very obliquely, almost parallel with the upper arm of 

 the bone ; their crowns scarcely oblique, close together, each with a 

 raised edge and grooved in middle. Dorsal inserted midway be- 

 tween snout and end of anal, its height equal to its base, free mar- 

 gin emarginate. Pectorals nearly as long as head, shorter than 

 ventrals. Ventrals inserted under seventh ray of dorsal, midway 

 between tip of snout and base of caudal. Caudal deeply forked, 

 middle rays scarcely more than a third as long as longest, upper 

 lobe two in body behind head. Depth of tail equals its length. 

 Lateral line descending above pectoral, straight posteriorly. Scales 

 finely striate. 



The specimens here described agree with the original description 

 except in the mouth parts, and these may vary. The original de- 

 scription, which was based on a specimen 33 cm. long, says that 

 there is but one pair of barbels, and that the middle of the upper 

 lip is smooth. I do not feel like basing a new species on these speci- 

 mens when they are so nearly like one described from the same 

 territory (Hong Kong). 



Acanthorhodeus dioseus Rutter, new species. 



Allied to Acanthorhodeus guichenoti Bleeker, Acad. Royale Mer. des Sci- 

 ences, Amsterd., 1871, Deel XII, pi. 13, fig. 2.
