 the dorsal has twelve spines ; no teeth on the palate.

D. 12/11. A. 3/8. C. 18. P. 16. L. lat. 46, and 5 on 

 the Caudal. L. tr. 8£/16£. 



Height three and two-thirds in total length ; the head three and 

 six-tenths m the same. General form very much like Murrayia 

 Bramoides. Posterior limb of the preeoperculum straight, and 

 finely serrated, the denticulations becoming much larger towards 

 the angle and on the inferior edge. The two spines of the opercu- 

 lum are, the first bifid, and the second tridenticulated ; the dorsal 

 has its fifth spine sensibly longer than all the others ; the twelfth 

 is longer than the preceding one. The first anal spine is small ; 

 the second very thick, but not longer than the third, and blunt. 

 The first ray of the pectorals prolongated in a rather long fila- 

 ment. 



Same colours as Murrayia Bramoides, but the head of a more 

 fleshy colour. 



Murray. I have only seen one specimen.
