Mr. J. Y. Johnson on new Fishes from Madeira. 77 
ving teeth, which cross one another from opposite sides of the mouth; 
these are moveable, and are the longest teeth in the upper jaw. At 
the fore end of the lower jaw there is a pair of very small teeth in 
front of a larger pair of immoveable teeth, which curve outwards. 
Next to these are two pairs of still longer moveable teeth, the hinder 
pair being the longest in the mouth. The other jaw-teeth are much 
smaller. On the palatines there is a series of small pointed teeth, 
and the middle line of the tongue is serrate. The vomer is promi- 
nent, but toothless. The tongue is grey, narrow, and free near the 
tip. There is no barbel, nor are there any pseudobranchiz. 
The anterior dorsal fin has eleven weak unbranched rays. It 
commences over the posterior edge of the opercle; and its base is 
rather less than half the length of the head, its height being about 
the same. The second dorsal fin is separated from the first by a 
space equal to about one-third the length of the head. It has a 
trapezoidal shape, and a longer base than the first dorsal. Its height 
in front is rather more than half the length of the head. The fourth 
and fifth rays are rather longer than their neighbours. 
The pointed pectoral fins are inserted in a line with the eyes, and 
reach back to the commencement of the second dorsal fin. 
The thoracic ventral fins are only about half as long as the pec- 
toral fins ; their apices are truncate, the first ray being the shortest. 
All the rays are weak, and none are detached. 
The anal fin commences about the middle of the total length of 
the fish, under the fifth or sixth ray of the second dorsal fin. The 
length of its base is equal to about two-thirds of the length of the 
head. It becomes low behind. The first ray is short; the second 
only half as long as the third; the sixth and seventh are the longest. 
The caudal fin is furcate, and equal in length to two-thirds of the 
length of the head. There are about fourteen principal rays, with 
a few small ones at each side. ' 
The lateral line is oblique in the pectoral region, but for the 
greater part of its length is straight along the middle of the body. 
An air-bladder of moderate size is present. No anal papilla was 
observed. 
A single example of this new genus of Malacopterygian Fishes 
was taken in the month of March, and has been deposited in the 
British Museum. Its stomach contained the doubled-up body of 
an entire fish nearly twice its own length. The latter proved to be 
a specimen of Gonostoma denudata, Bp. (Faun. Ital. iii. 138), as 
stated in one of my papers on rare Madeiran Fishes, printed in the 
‘Ann. & Mag. Nat. Hist.’ 1862. The stomach of the fish now 
described was so much injured that some points of its structure 
could not be made out. ‘The greatest height of the fish could not 
be accurately determined, nor could the precise situation of the vent 
be ascertained. The stomach appeared to be capable of great ex- 
tension. The rays of the first dorsal fin were unconnected by any 
membrane, which, however, may have disappeared through rough 
treatment. The teeth forming the outer series in the upper jaw 
were about twenty-four on each side, exclusive of the longer teeth
