?86 FISHES OF INDIA. 



spine is " not quite one-third tiie length of the head," and it is manifestly improbable that 

 any Diagramma would have the length of its head equalling nearly three times the height 

 of the body when that height is " thrice and two-fifths in the total length." In fact the 

 form is similar to that figured as D. griseum, C.V. 



In the " Fishes of Zanzibar " it was pointed out that D. griseum was subject to 

 variations in colour, and one was figured showing four whitish curved cross bands. There 

 is no genus of Asiatic marine fishes with more variation in the colour of individual 

 specimens and local races than shown in that oi Diagramma. While I stated that in the young 

 some sinuous and narrow light blue lines exist over the snout and cheeks, and also several 

 sinuous blue lines taking an oblique direction from the head upwards, and which extend to 

 nearly the length of the body.
