298 REPORT— 1844. 



Toute la fosse orbitaire entre le preopercule et le sous-orbitaire est recou- 

 verte d'ecailles semblables a celles du corps. 



Les maxillaires superieurs sont presque entierement caches sous les sous- 

 orbitaires ; ils sont elargis en arriere et engrenes en avant avec la branche 

 montante de I'intennaxillaire. Celui-ci est court, courbe en arc et garni sur 

 son bord inferieur d'une rangee de fortes dents crochues, dont la longueur 

 diminue d'avant en arriere. 



Les maxillaires inferieurs sont courts et hauts ; ils sont garnis, comme les 

 intermaxillaires, de dents crochues qui en arriere sont en simple rangee, tan- 

 dis qu'a la symphyse il y en a plusieurs placees les unes derriere les autres. 

 Les dents diminuent en arriere de la meme maniere que celles de I'inter- 

 maxillaire ; on ne remarque pas de canines plus saillantes que les autres. Je 

 ne saurais dire si le palais et la langue etaient aussi garnis de dents ; mais la 

 position generique de notre poisson me fait presuiner qu'ils etaient lisses. 



Les pieces operculaires sont couvertes de plusieurs rangees d'ecailles tout 

 a fait semblables a celles du corps. L'opercule lui-meme etait beaucoup 

 plus haut que long, et formait un trapezoide a angles posterieurs arrondis. 

 Son bord libre est mince mais entierement lisse, aussi bien que celui du pre- 

 opercule. La ceinture thoracique est extremement forte, elle forme en arriere 

 vers la gorge, un coin arrondi, au devant duquel se trouve dans un creux, I'ar- 

 ticulation de la nageoire pectorale qui etait assez petite, a ce qui parait, mais 

 dont je ne saurais rien dire de plus, ne I'ayant jamais vue conservee en entier. 



Les nageoires ventrales etaient placees au dessous de la gorge, peut-etre 

 meme un peu plus en avant que les pectorales. 



La dorsale commence iramediatement derriere la nuque par des epines 



radiating plaits. The whole of the orbital fossa between the preoperculum 

 and the suborbital is coated with scales resembling those of the body. 



The upper maxiilaries are almost entirely hidden under the suborbitals ; 

 they are widened behind, and in connection anteriorly with the ascending 

 branch of the intermaxillary, which is short, curved like a bow, and furnished 

 on its lower margin with a series of strong, crooked teeth, whose length di- 

 minishes from the front hindwards. 



The inferior maxiilaries are short and high ; they are provided like the 

 intermaxillaries with crooked teeth, which hindwards are in simple rows, 

 while at the symphysis there are several placed one behind the other. The 

 teeth diminish hindwards in the same manner as those of the intermaxillary ; 

 the canines are not observed to be more projecting than the others. I am 

 not able to say whether the palate and the tongue were likewise provided with 

 teeth, but the generic position of our fish leads me to presume that they were 

 smooth. 



The opercular pieces are covered with several rows of scales perfectly 

 similar to those of the body. The operculum itself was much higher than 

 long, and formed a trapezoid with rounded posterior angles. Its free margin 

 is thin but entirely smooth, which is also the case with that of the preoper- 

 culum. The thoracic girdle is extremely strong ; it forms hindwards towards 

 the throat a rounded angle, in front of which, situated in a hollow, is the ar- 

 ticulation of the pectoral fin, which was rather small, at least so it appears, 

 but of which I am able to say nothing further, never having seen it preserved 

 entire. 



The ventral fins were placed beneath the throat, perhaps even a little more 

 in front than the pectorals. 



The dorsal fin begins directly behind the nape with very strong and long
