PSEUD APHBITIS. 



The new specie I propose here is formed on a fish manifestly 

 belonging to the TracMnidce of Grunther, and to his group of 

 Tracliinina, but forming, on account of its eyes, placed obliquely 

 at the upper part of the head, a passage to his Vranoscopina. 

 The cleft of the mouth is rather oblique ; there are two dorsals ; 

 ventral s jugular, with nine spines and five soft rays ; no canines. 

 Almost all this would agree with Aphritis, but the scales are 

 rather large ; the first dorsal has seven rays, and just in front 

 of the anal there is a short fin composed of two spines. 



PSEUDAPHEITIS BASSU. 



General form of the body oblong, rather cylindrical, and elon- 

 gate ; cleft of the mouth rather oblique, with the lower jaw 

 longer than the upper one ; eye placed obliquely on the supe- 

 rior part of the sides of the head. Height of the body seven and 

 one-third times in the total length ; head conical, four times in 

 the same ; eye six and three-quarters in the length of head. 



The lateral line runs straight all along the body, over fifty- 

 nine scales ; the transverse line is formed of twenty scales, rather 

 large and ciliated, of which six are over the lateral line. A longi- 

 tudinal silicate extends on the centre of the back from the 

 posterior part of the head to the base of the dorsal ; the head is 

 entirely covered with scales ; the prseoperculum is entire ; the 

 operculum is terminated by a broad flat point. 



The first dorsal with one spine and seven rays ; it is rather high ; 

 second dorsal inserted near the first ; it is formed of twenty rays ; 

 the caudal is rather large, subtruncated, with the angles rather 

 prolonged, and formed of twelve long rays ; anal similar to the 

 second dorsal, formed of twenty-two rays, and in front are two 

 small spines, rather curved, each supporting a small membrane, 

 and adjoining the soft rays ; the first spine being longer than the 

 other ; ventrals placed in front of the pectorals, and formed of 

 one spine and five rays ; pectorals rather large, and formed of 

 eighteen rays ; teeth very numerous on each jaw, cardiform, 

 sharp ; others similar on the vomer and palatines. 



The upper parts are brown, with a few very faint transverse 

 broad green bands on the bach ; sides of the head purple ; 

 the colour is red in front of the eyes ; lower parts white ;
