3. 0[922) GREY MULLETS OF TUTICORIN 81 (I) The broad and flattened upper surface of the head ; (2) the broad and very thick adipose eyelids, which extend some distance across the pupil of the eye; (3) the dark blue band across the base of the pectoral fin ; and (4) the peculiar shape of the lower jaw, the mandibles bending towards the middle, at the angle of the mouth. [...] The length of the pectoral fin is as long as, or very slightly longer than, the length of the head ; but Giinther says it is " some- what shorter than the head. " The height of the body is rather greater than the length of the head, and approximately the same as the length of the caudal fin. [...] The length of the head, the length of the caudal fin and the height of the body are approximately equal, but the length of the head is usually slightly the greatest. [...] The length of the head is 3%3 to 4 times the diameter of the eye, again chewing much narrower limits of variation than those allowed by Bleeker, viz. , 31/2 to The length of the snout is usually 5i7 of the diameter of the eye, but may be 4; to 6 7. The least depth of the tail is less than the length of the head, and short of the length of the postorbital part of the head. [...] The length of the head, the height of the body and the length of the caudal fin are about the same, but the first is usually a trifle greater than the others.
