180 DR. J. E. GRAY ON CAMAROON MAMMALS. [June 10, 
which, however, the following differences distinguish it:—1. The 
height of the body to the total length is as 1 to 3%, not as 1 to 25. 
2. The diameter of the eye is to the length of the head as 1 to 35, 
not as 1 to 23. 3. The number 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 13. 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 flat spines. 6. In P. 
macrophthalmus 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. 
macrophthalmus. 
This species is established on a single specimen, taken last May, 
which had a length of 143 inches, and a height of 33, the head bemg 
34 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.

‘Squirrel from the Camaroon Mountains, 7000 feet above the

I have great pleasure in naming this beautiful new species after 
Mrs. Isabel Burton,—her husband, the discoverer of it, having re- 
clases that any novelty that might be in the list should be so 
named.
