FISHES OF INDIA. 
spine is “ not qnite one-tliird tlie lengtli of the head,” and it is manifestly improbable that 
any Diagramma wonld 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.Y. 
In the “ Fishes of Zanzibar ” it was pointed out that D. g/iseum 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 of 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.
