FISHES FROM MISAKI. 



2 S 



on both sides ; number of the band 4 on spinous dorsal, 1 1 on soft 

 dorsal and 19 on anal ; a blackish oblong spot on some anteriormost 

 rays of dorsal ; caudal whitish. Pectoral also whitish, with a blackish 

 patch at base. A line from tip of snout to upper end of gill-opening 

 blackish ; head above this line brownish, the lower parts whitish or 

 dusky or with some reticulation. 



The ground colour is variable to some extent ; markings of body 

 and the median row of short lines also variable, sometimes wholly 

 wanting. But the whitish bands lined with blackish lines on the 

 vertical fins are invariably present. 



In a specimen, measuring 6.7 cm. in length measured to tip of 

 tail, there are distinctly visible a blackish spot on the origin of dorsal 

 and an oblique line extending from above corner of mouth across 

 eye to upper edge of gill-opening. A very faint scries of short lines 

 along the median parts of body ; other markings on body scarcely 

 present. Markings of vertical fins very indistinct unlike other speci- 

 mens, in which these markings are constantly very distinct, even when 

 other markings on the rest of body are indistinct. 



The species is very closely allied to Zoarchias veneficus Jordan 

 & Snyder, but differs from this in having less number of rays on 

 spinous dorsal, soft dorsal and anal, and in the markings. Although 

 the ground colour and the marking are variable to some extent, the 

 marking of the vertical fins always forms prominent character of the 

 species. 



Eighteen specimens of the species were taken together with 

 Zoarchias veneficus Jordan & Snyder in tide-pools at Jogashima and 

 Bishamon (both near Misaki). 



The type, 7 cm. long as measured to tip of tail, is contained in 

 the Zoological Museum, Science College, the register number being 

 1969.
