seventy mm. are of an yellowish ochre on the dorsal half of the body 

 with bluish tint on the dorsum. Beautiful scales of a sky-blue-colour 

 in front of the dorsal fin. Irregular markings of sepia-brown-colour 

 forming a straight line along the lateral line, below which the ground 

 colour of the body fades away into a pale blue. Sepia brown blotches 

 are found also along the back. The ground colour of the dorsal half of 

 the head is yellowish ochre as in the body, with sepia brown markings 

 on the dorsal part of the upper jaw, the space between the eyes and the 

 neck. The ventral half of the head is of the same colour as of the body. 

 The pupil of the eye indigo-black, surrounded by a ring of sky-blue- 

 colour. All the fins yellowish ochre, the terminal portion of the dorsal, 

 the ventral and the anal, as well as the median portion of the caudal, of 

 a lighter colour. A row of elongated black streaks on the upper third 

 of the dorsal fin between the fin-rays. This fish was obtained in 

 Maebara. 



Larger individuals of about 105 mm, were obtained in Matsubara. 

 They are brown on the dorsal part of the head above the eyes, the 

 greater part of the body and the caudal fin. The sides of the head are 

 bluish, and passes gradually to light crimson towards the ventral side. 

 The lips are of a pale blue-colour ; the pupil of the eye, black with a 

 ring of a bright crimson. The dorsal third of the body darker brown 

 with traces of indigo tint. The dorsal two-thirds of the body are 

 covered with sepia coloured scales. The dorsal, the pectoral, the 

 ventral and the anal fins are light brown, and with a light indigo-colour 

 on the anterior parts of the dorsal and the ventral fins. The ventral 

 and the anal fins also edged with a light indigo colour. The basal third 

 of the caudal fin with longitudinal streaks of a brown colour. This is 

 known by the name of Aburahae. 



The largest specimens of this fish we got in Otsu were nearly 170 

 mm. in total length, and are again of a quite different colouration from 

 either of the two preceding. The upper half of the body is deep indigo- 

 blue with darker-coloured scales scattered over it. The ventral half 

 yellowish, becoming quite light on the ventrum, and with scales of
