the caudal. The head enters 4J times in the length. The width of the fore- 

 head exceeds a third of the head's length, while the diameter of the eye is less 

 than a third. The scale in the centre of the forehead is nearly square and 

 nearly equal to the distance between its sides and the orbits. The four granu- 

 lated areas in front are of considerable extent and behind the area is trans- 

 verse and confluent. The preoperculum is slightly produced at its angle. The 

 peGtoral fin extends nearly to the base of the caudal; the ventral is inserted 

 midways between the operculum and the axilla of the anal fin, and extends to 

 about the middle of the base of the latter.

The dorsal commences over the twenty-fifih scale from the scapular region, 

 and ends over the thirty-eighth. 



The color of the pectoral fins is deep blue, with the uppermost branch of each 

 ray white. The ventral is immaculate, except at the axil and a faint spot about 

 its centre. The caudal is deep blue. The dorsal is also blue between its fifth 

 or sixth and last rays ; the anal immaculate. 



One specimen eleven inches long is in the collection.

The greatest height is contained 4 times in the length to the end of the median 

 caudal rays, and 4h times in the total. The head equals the height, and is 

 itself longer than high ; the profile in front of the eyes rapidly declines down- 

 wards, and is nearly rectilinear. The diameter of the eye enters 3J times in 

 the head's length, and the height of the preorbitar 2| times. The supra- 

 maxillar ends at the vertical from the front of the eye. The teeth in front of 

 the upper jaw are biserml ; below uniserial. The first dorsal fin is highest at 

 the third spine, and there equals the head in front of the preopercular mar- 

 gin ; the .first is exceedingly short, and the second and fourth nearly equal and 

 little shorter than the third ; all the spines are very slender towards the ends. 

 The distance of the second from the first dorsal enters If times in the base of 

 the former and in that interval are three scales ; its length is less than that of 

 the first. The ventral equals the distance of the hinder margin of the orbit 

 from the snout. 



The tubes of the lateral line have slender branches diverging from them, 

 generally directed obliquely upwards. The larger scales have six radiating 

 striae.

The color is light greenish-brown above, with an indistinct silvery spot at 

 the centre of each scale. Below the lateral line, especially between it and the 

 anal fin, the color is rose. The dorsal fins covered with spots of the color of the 

 back. The others are immaculate. 



Two specimens, the longest of which is seven inches and a half long, are in 

 the collection.
