232 ACANTHOPHTHALMUS SHELFORDII. 



the subocular spine is not colored and hardly reaches past 

 the orbit; the gill-openiug is twice the diameter of the 

 eye; the muzzle is '/g of the length of the head; the 

 opening of the mouth is underneath, ouce the diameter 

 of the eye from the end of the muzzle; six barbels, two 

 rostrals and four maxillars, the barbels are small, not longer 

 than a millimeter, the underlip is cloven. 



The dorsal fin lies before the vertical line of the be- 

 ginning of the anal fin for a distance as long as the base 

 of the dorsal fin, the distance between the dorsal fin and 

 the caudal fin is a little more than one-fourth of the total 

 length (without caudal) ; the height of the pectoral fins is 

 */jg of the length of the head, the distance between the 

 base of the pectoral and ventral fins is nearly 5 times 

 the height of the pectoral fins ; the ventral fins are situated 

 in the middle of the total length (with caudal), the height 

 of the ventral fins is "/^ of the height of the pectoral fins, 

 the distance between the base of the ventral fins and anal 

 fin is 4 times the height of the ventral fins ; the anal fin 

 is as high as the pectoral fins and a little higher than 

 the dorsal fin, the distance between the base of the anal 

 fin and caudal fin is twice the height of the anal fin ; the 

 caudal fin is truncated. 



The colour is a soft reddish with brown spots, the spots 

 are on the back and the sides of the body and the head, 

 there are none on the ventral side; the colour of the 

 pectoral fins, ventral fins and anal fin is a uniform soft 

 reddish just as the ventral side, the dorsal fin and caudal 

 fin have brown streaks. The brown spots on the back and 

 the sides are large, their form is irregular, their size is 

 different, they are situated in three rows , one on the 

 somewhat flattened back and one on each side, the spot 

 on the nape of the neck mixes with those of the sides , 

 in the same way some of the spots of the back join on 

 one or on both sides the spots of the sides.
