No. 4. Lieut. Emery's drawings. 



The specimen from which Lieut. Emery made his drawing 

 was taken in Talc Bay, and measured eight inches in length, 

 and fifteen between the extended tips of the dorsal and anal 

 fins. The figure does not agree in all points with the e Kahi- 

 sandawa of Russell, which is the Platax Leschenaldi of the 

 c Histoire des Poissons/ but it resembles it so much, that it 

 seems better to direct the attention of naturalists to it under 

 that designation, rather than under a new specific name. 

 Russell describes four vertical bands as existing in the young 

 of the Kahi-sandawa, and states that they disappear as the fish 

 increases in age. The wide range of the Kahi-sandawa, from 

 India to New Guinea, increases the probability of its being 

 also an inhabitant of the seas which wash the northern coasts 

 of New Holland. 



Lieut. Emery's drawing represents the dorsal and anal fins as tri- 

 angular in profile, their posterior edges being not falciform, but al- 

 most perfectly straight. The height of the dorsal rather exceeds 

 that of the body, and is considerably greater than that of the anal. 

 The caudal terminates in a slightly waving line, convex in the mid- 

 dle and a little concave towards the two angles, which are acute. 

 The pointed ventrals reach half way along the anterior border of the 

 anal. The profile is steeply convex from the mouth to the ventrals, 

 and also upwards to the beginning of the dorsal, which rising still 

 more precipitously, renders the outline slightly concave before its 

 base. The height of the body, measured a little obliquely, from the 

 base of the first jointed dorsal rays to the beginning of the anal, is
