which, however, the following diiferences distinguish it: — 1. The 

 height of the hody to the total length is as 1 to 3-^, not as 1 to 2|. 

 2. The diameter of the eye is to the length of the head as 1 to Si, 

 not as 1 to 2|. 3. The numher of soft rays in the dorsal fin is 15, 

 not 13 or 14. 4. The length of the second dorsal spine is to the 

 last as 1 to 2, not as 1 to If . 5. The edge of the opercle has one 

 flat spine, and above this there is a rounded plate ; whereas the edge 

 of the opercle of P. macrophthalmus has two fiat spines. 6. In P. 

 maci'ophthalmus the two borders of the preopercle form a right angle, 

 and the margins are strongly denticulated. In the present species 

 the angle formed by the free borders of the preopercle is obtuse, and 

 the margins are very finely serrate. 7. The caudal is slightly emar- 

 ginate. 8. The fins have not black edges, as is the case with P. 

 maei'ophthalmus. 



This species is established on a single specimen, taken last May, 

 which had a length of 14^ inches, and a height of 3|, the head being 

 3|- inches long. The eye had a diameter of 1-^ inch. The example 

 was coloured a uniform red, and it is now in the British Museum.

I have great pleasure in naming this beautiful new species after 

 Mrs. Isabel Burton, — her husband, the discoverer of it, having re- 

 quested that any novelty that might be in the list should be so 

 named.
