hidden. Uncovered portion of chin very narrow ; a deep groove 

 across the palate in front of the vomer. Teetli minute. Fins 

 first dorsal commences midway between the snout and base of 

 caudal ; spines stout, not quite so high as second dorsal, but equal- 

 ling length of postorbital portion of head ; second dorsal com- 

 mences opposite anal, they are of equal height and scaled. First 

 and second dorsal arise over 12th and 24th scales of lat. line respec- 

 tively. Caudal lunate. Scales cycloid. An elongate, pointed 

 scale in the axilla. Colour silvery, light on sides and beneath ; a

Uab. Mauritius, and from Bombay through the seas of India to

Length of head 4|, of caudal fin 4|, height of body 4| in the total 

 length. Eyes without adipose lids ; diameter 4 in length of head, 

 1 diam. from end of snout, and 1| apart. Preorbital strongly bent 

 and serrated, end of maxilla visible ; the mandibles form rather an 

 obtuse angle, are notched at their point of junction, and have a 

 distinct knob. Upper lip moderately thick, placed obliquely so as 

 not to form end of snout. Uncovered space below the chin narrow,

 midway between front edge of the eye and base of caudal fin, length 

 of spines equals postorbital portion of head ; second dorsal rather 

 higher. First and second dorsals commence over llth and 24th 

 scales of lat. line respectively. Pectoral inserted above middle of
