PsEUDOMURENA, gen. nov. 
Dorsal, anal, and caudal fins united; no pectoral fins; gill-open- 
ings lateral; no teeth on the mesial line of the palate ; in the jaws 
uniserial serrate teeth, having a tubercle at the posterior base. 
This genus differs from Murena in having no teeth on the mesial 
line, and in the forr.: of the jaw-teeth. 
PsEUDOMURENA MADERENSIS, Sp. nl. 
Body anguilliform, attenuating backwards from the nape, which is 
deep and thick. Skin soft, thick, scaleless. Colour a yellowish 
brown, darker on the head; the anterior fourth of the body marked 
with undulating lines, or narrow bands, of deeper brown, which are 
arranged longitudinally before the gill-openings, and transversely 
behind them, the change of direction being gradual. 
The head is gibbous behind the small eyes, which are oval, covered 
with skin, and placed over the middle of the upper jaw. The snout 
is obtuse and rounded; the throat swollen. The posterior nostrils 
are small, with slightly raised borders, and are placed a little in front 
of the vertical through the middle of the eye. The anterior nostrils 
issue in free tubes, which do not quite reach to the tip of the snout. 
The jaws are of moderate length and subequal; the lips moderately 
thick ; the inside of the mouth fuscous. The teeth are uniserial, 
rather stout, pointed, conico-compressed, with serrate edges, and a 
tubercle at the posterior base. They are slightly curved backwards, 
and are longer in front than behind. In the upper jaw there are 
about 16; in the lower jaw from 24 to 34. No teeth on the mesial 
line or on the vomer. Rictus moderate. No barbel. Gill-openings 
small, round, placed at the sides of the body about the middle of 
the height. No pectorals or visible lateral line. The dorsal fin 
commences at the nape, in front of the gill-openings, and is conti- 
nuous with the caudal and the anal fins; it is higher behind than in
