star-like spots; more slightly coloured along the back with some 

 transverse bands , which are more faint backward , and none 

 appear near the tail. The lower half of the pectoral fins have 

 colour, but the upper portiou are without it. Two or three rays 

 on the inner portion of the ventral fins are black." 



From this descriptiou we see that the colours of the adult form 

 begin to appear as soon as the little fish has reached a size of 

 between IG and 18 m.M. The transverse bands of colour just 

 made their appearance in the specimen of 18,75 m.M. in length.
