ZOOLOGY OF THE VOYAGE OF THE BEAGLE. 



There is one soft ray less in the dorsal, and three less in the anal ; also the first 

 spine in this last fin, if it be not broken ofTin this specimen, is quite rudimentary. 

 The scales present no trace of cilia on their free edges.

Form.— Body thickest, as well as deepest, in the region of the pectorals, compressed behind, and 

 becoming more so as it approaches the tail; depth also gradually diminishing from that point. 

 The greatest depth is rather less than five and a half times in the entire length : head contained 

 four times and a quarter in the same. The thickness at the pectorals is at least three-fourths of 

 the depth : and the thickness of the head is quite equal to it. Dorsal line nearly straight from be- 

 hind the eyes, in front of which the profile descends obliquely. Eyes high, nearly reaching to the 

 line of the profile ; a little behind the middle point of the length of the head ; their diameter 

 rather less than one-fifth of this last ; the distance between them one diameter and a half. The 

 commissure of the lips does not reach to the eyes by a space equalling half the diameter of the 

 eye. Jaws equal. Lips very thick and fleshy, and partially reflexed, like those of a Lubrus. 

 Teeth very similar to those of that genus. In the upper jaw, an outer row (extending all round) 

 of strong, sharp, slightly curved teeth, regularly set, and nearly even, but with the anterior 

 ones a little the longest ; in all about forty, twenty on each side ; behind these a velutine band, 

 broadest in front, but also extending the whole way round. In the lower jaw, a row of curved 

 strong teeth, similar to those above, but extending only half way along the sides of the jaws 

 (about nine on each side), and followed by about seven or eight short blunt conical ones ■ a 

 broad velutine band behind the longer curved teeth, but not behind the others. On the front of 

 the vomer are four or five large blunt conical teeth, mixed with smaller ones of the same form: 

 there is also a small group of these little conical teeth at the commencement of each palatine, 

 but they are not carried on further in a single row * Tongue small and inconspicuous, fastened 

 down except just at the tip, smooth. Pharyngeal teeth in strong card; but no conical ones 

 behind that are visible. Branchial membrane united to its fellow, and free all round at the 

 margin, with a moderately deep notch underneath. Preopercle rounded at the angle- the 

 ascending margin oblique. Opercle with a strong sharp spine at its upper anole, but not ex- 



* As described by Cuvier and Valenciennes to be the case in the P. Brasilianus.
