are smaller but most distinct on tlie second dorsal. Anal with a row of blue spots along its base, and a gray 

 external edn-e. Five or six vertical and sinuous bands of spots on the caudal. In some specimens, more 

 especially in° those wanting the crest on the head, the bands along the body are not well marked. 



This fish not only differs in the number of fin rays from S. Itnpatus, but also in possessing canine teeth. 

 The marks on its dorsal fin are horizontal instead of being oblique. There are several specimens in the Calcutta 

 Museum.

Length of head 5f, of caudal 6, height of body 7 to 8 times in the total lencth. Eyes—m the anterior 

 third of the head, the interorbital space concave, with a slight ridge along its centre, profile ft'om eyes to snout 

 prominent, but not overhanging the jaws. The greatest width of the head equals rather above half its length, 

 and its height equals its length behind the eyes. The maxilla reaches to below the hind edge of the eyes. A 

 rather large rounded crest on the head. A simple supraorbital tentacle as long as the eye, a short fringed one 

 at the nostrU, none at the nape. Teeth — a pair of rather small canines in the lower jaw. Fins— a. deep notch 

 between the two dorsal fins, posteriorly it is continued on to the base of the caudal fin : first dorsal two-thirds 

 as high as the body, the second posteriorly as high as the body. Lower pectoral fin rays longer than the upper 

 ones. Anal as high as the first dorsal. Colours— greenish stone-coloured, with some bluish spots on the head 

 near the eyes, about eight pairs of vertical streaks on the body, and sometimes eight or ten longitudinal dark 

 ones. Dorsai more or^less marked with brown, which in places forms spots : oblique brown marks on lower 

 half of the second dorsal, and a dark outer edge. Anal with a dark outer edge. Caudal dark, with six or seven 

 narrow vertical bands.

Length of head 5 to 5|, of caudal 6 to 7, height of body 5 to 5| in the total length. Eyes— rather 

 prominent, U to 2 diameters from end of snout, 1/2 a diameter apart. Interorbital space slightly concave. 

 The height of the head equals its length excluding the snout, its width is rather less. The forehead does not 

 project loeyond the mouth. In the male a well developed crest on the occiput, and a fringed tentacle twice as 

 lonw as the eye above the orbit : another short one at the anterior nostril. In the female no crest on the neck, 

 a fringed tentacle about as long as the eye above the orbit, and another short one at the anterior nostril. 

 Teeth— no canines. Fins— a. deep notch between the two })oi-tions of the dorsal fin, the anterior being much 

 lower than the posterior ; the fin not continuous with the caudal, which last is cut nearly square. ^ All the fin 

 rays simple, except those of the caudal. Colours— in the male olive brown, with distinct blackish blotches 

 along the side and extended on to the dorsal fin : two or three rows of blue spots on the body and head. The 

 female olive brown, becoming white beneath, and marbled all over with brown lines forming large msiilated 

 spaces. Head and upper two-thirds of the body dotted with Ught blue : fins yellowish : dorsal and anal, 

 horizontally and sinuously banded in spots : caudal wdth five or six vertical dark bands. A brown band, chvided 

 by a light blue line, at the base of the pectoral, which is yellowish barred with brown. 



Habitat.— ned Sea, East coast of Africa, and Kurrachee, from which latter place the specimens figured 

 (life-size) were procured. ♦

Length of head 6, of caudal 7, height of body 5^ in the total length. Eyes— high up, the profile to the 

 snout slightly oblique, not overhanging the jaws. Greatest width of head equals its length behind the eyes, 

 and its width equals its length excluding the snout. A low crest on the head ; a fringed tentacle half as high 

 as the eye above the orbit, a similar one at nostril, but none at the nape. Maxilla reaches to below hind edge 

 of eye. Teeth— a Small posterior canine in the lower jaw. Fins— the first dorsal slightly lower than 

 the second, the two being divided by a deep notch, the second, which is two-thirds the height of the body, is 

 not continued to so far as the base of the caudal fin, which is rounded. Colours— light brown, with eight pairs 

 of well marked vertical bands as wide as the ground colour. An oval blue spot behind the eye. Many small 

 round ones with a dark edge on the head : two rather large brown ones at the base of the pectoral fin, which is 

 brownish. Two or three rows of white spots in the lower and posterior h.-ilf of the body. First dorsal brown, 

 with some oblique brown bands : second dorsal white, with some oblique dark bands. A dark spot 

 at base of caudal, which is banded with brown spots. Anal light-coloured, with a dark outer edge, which
