on the crown becomes narrower posteriorly, and is nearly twice as 

 long as broad. Thi'ee praeopercular spines, two of which are at the 

 angle ; the upper is the longest, its length being equal to the dia- 

 meter of the eye, but less than the width between the orbits. The 

 height of the first dorsal is somewhat more than the length of the 

 maxillaiy bone ; the ventral terminates at a great distance from the 

 vent, and the pectoral does not reach to the anal. Skin above the 

 lateral line with smooth warts. Brownish, spotted with darker 

 (colours faded).

Description of the specimen. — The greatest height of the body, in 

 front of the dorsal, is 4| in the total length ; its greatest width, 

 behind the pectoral, foui" times. The tail tapers much posteriorly, 

 and its height, before the caudal, is twenty-one times in the total 

 length. The head is moderately broad and depressed ; its length is 

 3| in the total. The cleft of the mouth is moderate, the maxillary 

 reaching to the vertical from the centre of the eye ; the snout is not 

 very obtuse, and the upper jaw slightly overhangs the lower ; there 

 is a pair of small spines above the snout. The space between the 

 eyes is slightly concave, and its "width rather more than the hori- 

 zontal diameter of the eye ; there is an obtuse protuberance above 

 the posterior angle of the orbit, from which a slight ridge proceeds 

 to the occipital protuberance ; the latter is very little prominent, 

 and furnished with a small skinny tentacle. The impression be- 

 tween these two pairs of protuberances is shallow, and becomes 

 narrower posteriorly, being nearly twice as long as broad. The 

 praDoperculum is anned with three spines, two of which are opposite 

 the infraorbital, the third being situated at the inferior extremity 

 of the bone, and pointing downwards. The suboperculum has a 

 single spine anteriorly, directed downwards ; throat without spines. 



The spinous do^'sal begins at a distance from the head which is 

 rather less than the length of the impression of the crown ; it is not 

 continuous with the soft. The fourth spine is the longest, its length 

 being somewhat more than that of the maxillary bone, and a little 

 less than that of the ninth ray. The caudal has the posterior mar- 

 gin slightly coiwex, and its length is 6| in the total. The anal is 

 formed by twelve rays, and begins in the vertical from the fifth dor- 

 sal ray, and terminates a little before the opposite fin ; its height 

 equals that of the spinous dorsal. The pectoral is composed of six- 

 teen simple rays, and reaches to the vent, which is situated nearly in 

 the middle of the total length. The root of the ventrals falls be- 

 hind that of the pectoral ; they terminate at a grc;it distance from 

 the vent, and are composed of one spine and three rays. The spine 

 is enveloped in the same membrane with the first ray ; the middle 

 ray is the longest, flat and compressed like the interior. 



The lateral line is continued to the caudal, and is composed of 

 elongate bony tubes, thirty-eight in number. This specimen is nearly
