the bones which are situated higher up the sides. The humeral is 

 formed as in the Pereidse generally, but rather shorter ; the urohyal 

 is triangular, short and broad. 



The p«6/c' bones are peculiarly shaped, short, much higher (in the 

 vertical line) than broad (in the horizontal) ; they are attached to 

 one another with an upper suture, terminating in a point anteiiorly, 

 and with a second vciy concave one in front. They form together a 

 trihedial cavity with the entrance from beneath ; each of them 

 terminates behind in a broad process, which together form a plate, 

 ill form not urdiko one of the scales of the fish. There is another 

 styliform process along the entrance to that cavity, arising from the 

 symphysis of the bases of the ventral fins. 



The hyal and branchial ajiparatus show no peculiarity. 



There are eleven abdominal and fifteen caudal vertebrce, the length 

 of the abdominal part of the vertebral column being 1-1- in that of 

 the caudal. The haemal spines are stronger and somewhat longer 

 than the neiu'al. Twelve ribs ; the fourth to the eighth rib have 

 another smaU rib (eijipleiu-al spine) attached ; but such epipleui'als, 

 belonging to the posterior ribs, are inserted on the vertebrae them- 

 selves. The ribs of the eleventh vertebra are very broad, sword- 

 shaped, and separated from one another. The strongest interhtemal 

 is apparently formed by two, belonging to the second and third 

 dermohffimals ; it has a deep longitudinal groove, and is as long as 

 the first eight vei'tcbrte together.
