the Genus Sjnajjtura, Cantor. 57 



jEsopia cornuta, Cuvler, young examples Lave the caudal fia 

 relatively longer and in its outer part free from the dorsal and 

 anal, exactly as in the case of S. ommatura. 



The three Japanese species admitted by Jordan and Snyder 

 must then be reduced to two — S. zebra, Bloch, and ^S^. omma- 

 tura, Richardson ; but 1 have to add one from a collection of 

 fishes recently made in the Inland Sea of Japan by Mr. R. 

 Gordon Smith ; this new species, belonging to the same section 

 of the genus, is described below under the name of Synaptuva 

 Smithii. I also describe here a specimen taken by the 

 ' Challenger ' in the Aratura Sea, which was referred by 

 Dr. Gilnther to S. zebra, Bloch, but apparently belongs to a 

 hitherto unknown species. 



Synaptura Smithii, sp. n. (PI. VI. fig. 1.) 



Depth of body 2-| times in the total length, length of head 

 5-| times. Eyes contiguous, the upper scarcely in advance of 

 the lower, subequal in size, their diameter about 4^ times in 

 the length of head and equal to the length of snout. Mouth 

 extending to below anterior part of eye. Nasal tube long, 

 pimple. D. 75; A. 62; C. 17; the posterior rays of dorsal 

 and anal connected to the basal part of the caudal, which is 

 quite distinct and rounded. The width of the base of the 

 caudal fin equal to half the length of head. The upper rays 

 of the right pectoral produced, equal to § the length of head ; 

 the left pectoral short, inconspicuous. Sc. 95 ^, ciliated, ex- 

 tending on the bases of the vertical fins in single series up 

 each of the rays, at the most — i. e., on the posterior rays on 

 tlie ocular side — not more than 8 in each series, not ex- 

 tending to the outer half of the fin ; those on the blind side of 

 the head mostly produced into barbel-like processes. 



On the ocular side greyish, with nine pairs of dark brown 

 cross-bands on the head and body, extending on to the vertical 

 fins as a series of black blotches. On the blind side pale 

 pink, the vertical fins white at the base and with a broad 

 black border. 



A single specimen, 120 millim. in total length, from the 

 Inland Sea, Japan, presented to the British Museum by 

 Mr. R. Gordon Smith. 



Synaptura callizona, sp. n. (PI. VI. fig. 2.) 



Depth of body 2| times in total length, length of head 5| 

 times. Eyes contiguous, the upper scarcely in advance of 

 the lower, subequal in size, their diameter about 4 times in 

 the length of head and equal to the length of snout. Mouth
