24 ART. S. — S. TANAKA : DESCPtirTFONS OF ONE NEW 



Colour in formalin g'ray, pale beneath ; about 11 cross bands 

 of brown colour, some of the bands forked above or even entirely 

 split into two; colour of the bands gradually fading out beneath 

 middle of side of body ; the first band across nape, the second 

 immediately in front of dorsal, the third to fifth below first 

 dorsal, the sixth to ninth below second dorsal, the tenth on 

 caudal peduncle and the last on base of caudal. In the middle 

 of caudal a. more or less distinct spot. Interorbital band very 

 indistinct, extending from below eye to angle of mouth. First 

 dorsal brownish, with a few rows of indistinct spots ; second dorsal 

 as well as anal much darker, the former with several wavy rows 

 of brown spots and with very narrow blackish edge ; anal with 

 or quite without several indistinct rows of spots, near its edge a 

 blackish line somewhat wider than that of second dorsal, edge itself 

 whitish. Both pectoral and ventral dusky, without distinct mark- 

 ings (in one specimen anterior edge of ventral brown). Caudal 

 dusky, with several rows of indistinct spots on proximal parts. 



The species seems to be very closely allied to Sicydium halei 

 Day from Ceylon known to me only from its original descrip- 

 tion, but differs from it in having stouter body, longer caudal, 

 and smaller eye. 



The type, 7.7 cm. long as measured to root of middle caudal 

 rays, w^as obtained by Mr. Oda in Tosa (Shikoku) ; its register 

 number in the university collection is 2138. Another specimen, 

 9 cm. long measured in the same ww as above, was collected by 

 Mr. H. Nakajima, in the Prefecture of Wakayama. That spec- 

 imen differs from the type in the following points : mouth ex- 

 tending to anterior edge of pu2~>il ; first dorsal much more fili- 

 form, extending to second ray of second dorsal ; caudal whitish 

 at posterior angles.
