244 REPORT—1845., Key meee 
Park. The post-frontal is ridged in a radiated way and slightly cancellated, and no scales 
could be discovered through the varnish on the cheeks or temples. The teeth are strongly 
tricuspid, the larger middle lobe rounded and crenated, the lateral ones acute. In the draw- 
ing an accessory or binate anal spine is shown, and the same thing is noticed by Park in his 
description of dmph. margaritiferus. The body is clouded with umber-brown and silvery 
blotches, occupying nearly equal space, but a dark tint prevailing onthe back. On the flanks 
and tail there are besides many small silvery dots. The throat is umber-brown, and the 
sides of the head are umber-brown and olive-green, shading into eachother. The caudal, 
soft dorsal, posterior half of the spinous part and soft anal are chestnut-brown. A cream- 
yellow stripe runs along the base of the anal. The ventrals, fore-part of the dorsal, and 
spinous portion of the anal are bluish-gray, and the pectorals straw-yellow with an umber- 
brown blotch on the base. Length 10 inches.

In Sir Edward Belcher’s collection there are several species of Acanthuride, among which is 
an adult Naseus brevirostris, and also specimens of Naseus lituratus, some of which may have 
been collected in China; but as this officer visited New Guinea, which has been recorded pre- 
viously as the native place of these fish, and he put fish from various localities into the same 
jars, we are unable to affirm that any of these specimens are Chinese.

I possess a drawing of a fish caught in the Bight of Benin by Dr. Thompson of the Royal 
Navy, which has the exact profile, the position of the ventrals and general appearance of M. 
Biirger’s figure published in the ‘Fauna Japonica,’ except that the ventrals have the red 
colour of the rest of the fish.
