blotches. The head is punctured with red, and has two irregular 
longitudinal lines on the prseopereulum ; the second is rather 
oblique ; the lips are marbled with light brown, and on the sides 
of the head are five or six round blotches, of a fine silvery hue. 
The dorsals and anal are transparent, covered with purple-brown, 
opaque lines, forming a sort of trellis wort ; the rays are brown, 
marbled with yellow ; those of the caudal are similar, and that 
fin is bordered with orange, as is also the soft part of the dorsal. 
The ventrals are striped yellow and purple ; the pectorals are 
dark ; the eye is pink, with an external series of red spots. 
I have only seen two specimens of this sort ; the largest 
measures 10|^ inches. 
This sort must have some resemblance to Forster’s Blennms 
Fenestratiis, but this is included by Cuvier and Dr. Gunther 
in the genus Tri-pterygimn. 
CEISTICEPS FOESTEEI. 
The body is very elevated in its anterior profile, and like 
gibbous over the head ; this bears a single, simple bifid filament 
over the eye. The height is contained four and a-half times in 
the total length ; the head four and one-third times in the same ; 
eye four and one-fourth times in the length of the head. The 
lips are thick and prominent. The first dorsal begins in front of 
the end of the operculum ; it is high, and formed of three spines. 
The second is separated from it by a small space, and is formed 
of twenty -nine spines and four rays ; these are rather higher than 
the spines ; the caudal is rounded, and formed of nine long rays ; 
the anal of twenty-six ; it is low at its anterior part, and goes on 
increasing towards its end, which is rounded ; the rays are con- 
siderably longer than their membranes its last ray is fixed by a 
membrane to the tail, but at considerable distance from the base 
of the caudal ; the last one of the dorsal is similar, but extends 
a little further backwards ; the ventrals have two rays, the ex- 
ternal short, the other long and bifurcated ; the pectorals have 
twelve rays. 
The general colour is green, with the sides of the head and 
the anterior part of the lower side of the body of an ochre 
yellow ; the lips are purple, and the lower portion of the prse- 
operculum carmine ; the dorsals, caudal and anal are green, with
