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 m 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 pseudobranchise. 



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, aud 

 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 liead. 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 tiie upper jaw 

 were about twenty-four on each side, exclusive of the longer teeth
