No. 3 (1922) GREY MULLETS OF TUTICORIM 9$ 



The length of the head, the height of the body and the 

 length of the caudal fin are usually of about equal length. Giinther 

 and Day give the height of the body as somewhat greater than the 

 length of the head. 



The first spine of the first dorsal fin, the length of the post- 

 orbital part of the head, and the width of the interorbital space 

 closely approximate each other in measurement, i.e., a little more 

 than Y 2 the length of the head. 



The length of the third anal spine is J/3 the length of the 

 head. 



Colour. — Preserved specimens shew the following colour 

 features : a dark axillary spot is present at the upper base of the 

 pectoral fin ; there is a dark spot above the centre of the eye ; the 

 front edge of the second dorsal and the edge of the caudal fins are 

 darkish ; the first dorsal is frequently tipped dark ; the base of the 

 anal and pelvic fins brown ; there is a brownish streak across the 

 head a little behind the eye ; and a white triangular patch behind 

 and below the eye ; the iris is light coloured. 



The specimens of this species at Tuticorin do not seem to 

 attain the size mentioned by Day who says an Andamans specimen 

 measured 13 inches, "but it is said to grow very much larger." 

 None of the specimens examined exceeded 14 cm. 



LIZA WAIGIENSIS {Quoy & Gaimard). 



D. 4 J 1/8. A. 3/8. L. I. 26. L. tr. 9. 



This species is scarcely so common as other species described, 

 except L. amarula; it is a small mullet, seldom more than 14 cm. 

 in length. It is most readily identified by the following charac- 

 ters :-— 



(i) Colour. — {a) Fins : The pectoral and both dorsals have a 

 considerable part of their surface black. The caudal fin is yellow 

 with a black edge. The anal and pelvic fins are orange coloured 

 with a black tip. Preserved specimens retain only the black 

 markings, {b) Prominent dark longitudinal lines along the rows 

 of scales. 



(2) The caudal fin only very slightly forked. 



(3) The pectoral fin reaches nearly, or quite, to the origin of 

 the first dorsal fin. 



(4) The number of rows of scales across the body is few (g).
