THE FISHES OF MALABAR. 143 



margin of tho mandibula forms a rather obtuse angle, and is slightly cmarginate at the symphysis. 

 The cleft of the mouth is more than twice as wide as deep. Interorbital space slightly convex. 

 Preorbital distinctly denticulated. Free space between mandibular lanceolate. 



Teeth — In a specimen 3^ inches in length, a row of fine teeth in the upper jaw is very 

 distinctly visible. 



Fins — Tho pectoral arises just below the middle of the height of the body, is rounded and 

 extends to the eighth scale. The first dorsal is triangular, its spines moderately strong and it 

 arises opposite the tenth scale of the lateral line. The second dorsal commences opposite tin 

 twenty-first scale, and above the fifth ray of the anal. Caudal cmarginate. 



Scales — Over body, head, base of soft dorsal, and anal rays. 



Colours — Silvery, with a greenish tinge along the back and golden reflections on the head. 



Grows to about four inches in length. 



Habitat — Seas and estuaries of India, entering rivers. 



B. Without adipose eyelids.

Length of head \, of pectoral ^, of caudal J, of base of first dorsal y 1 ^, of base of second 

 dorsal y 1 ^, of base of anal yy of total length. Height of head y 2 5 , of body \, of first dorsal T \,, 

 of second dorsal -^, of ventral ^, of anal ^ of total length. 



Eyes — Without adipose lids ; horizontal diameter T , and vertical diameter f of length of head, 

 rather more than ^ diameter from end of snout, 1J diameters apart. 



Body equally convex on its superior and inferior profiles. Head rather broad, and a slight 

 ridge from the upper surface of orbit to the base of the pectoral, the interorbital space rather 

 convex. 



Mouth transverse, its depth a fourth of its width. Upper jaw more rounded than angular^ 

 with a notch in its centre to receive the knob of the lower jaw, which is elevated in its centre, 

 and concave along either side. The free space is rather narrow and lanceolate in shape. Preorbital 

 irregularly triangular, with the base in front : it is convex as far as its bent angle, whilst its 

 superior margin has a hollow rounded notch, and its inferior angle is bent down, rounded, and 

 denticulated ; an oblique line of three open glands exists from between the notch to its external 

 angle. Preopercle, with a deep glandular notch opposite the lower margin of the orbit, and two 

 approximating just above its angle ; on its horizontal margin there is one at its angle directed 

 backwards, and one at its posterior extremity, and a third intermediate : there are also two or 

 three smaller and more circular ones, three along the lower edge of the mandibula, and two larger 

 ones along its inferior limb. Opercle with a notch on its posterior margin, close to the ridge. 

 Glands on the upper surface disposed as in the M. cunnesius. 



Teeth — None apparent in the lips : but on either side of the vomer is a strong, rounded, 

 smooth, transverse ridge. 



Fins — The upper margin of the pectoral is in the upper third of the body, and it has an elon- 

 gated scale at its axil : the fin is pointed, and extends to the tenth scale on the lateral line. First
