PSKUDAPHEITTS. 
Tbe neAV specie I propose here is formed on a fish manifestly 
belonging to the TracMnida of Gnnther, 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 TTranoscopina. 
The cleft of the mouth is rather oblique ; there are two dorsals ; 
ventrals 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. 
PSETjnAPHKITIS 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 sulcate 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-tAVO 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 jaAv, cardiform, 
sharp ; others similar on the vomer and palatines. 
The upper parts are broAAm, Avitli a feAV very faint transverse 
broad green bands on the back ; sides of the head purple ; 
the colour is red in front of the eyes ; lower parts Avhite ;
