Diagnosis. — Caudal rounded, the height of the body is contained thrice and one-third in 

 the total length, the length of the head four times and one-sixth in the same. Diameter 

 of the eye one-seventh of the length of the head. The upper maxillary bone reaches to 

 the vertical from posterior margin of orbit. Prseoperculum inconspicuously serrated 

 behind, the denticulation rather stronger at the angle. Sub- and interoperculum entire. 

 The third and fourth dorsal spines are longest and one-third the length of the head. 

 General ground-colour brownish yellow. Body with about fifteen more or less undulated 

 series of short brown streaks, which are sometimes confluent. Head with nume- 

 rous small round brown spots. The head and trunk show, besides, numerous rounded 

 lighter spots, as in S. tmnilabris, some of which have a brown spot in the centre. 



Description, — This species somewhat resembles S. altivelis. The neck is elongated, 

 the head strongly compressed and high, with its upper profile concave. The body is 

 elevated, its greatest height being below the origin of the dorsal, where it is contained 

 thrice and one-third in the total length. The length of the head is contained four 

 times and one-sixth in the same. The distance between the eyes is much less than 

 their diameter, and is covered with minute scales as far as the nostrils. The eye is 

 small, being one-seventh of the length of the head, and half that of the snout. The 

 upper maxillary bone reaches to the vertical from the posterior margin of the orbit. 

 The praeoperculum is inconspicuously serrated behind, the denticulation being rather 

 stronger at the angle. The sub- and interoperculum are entire. The lips are thick and 

 fleshy. The operculum terminates in three feeble inconspicuous spines, the middle one 

 being more remote from the first than from the third.
