The entire skeleton is perfectly ossified, and especially the oper- 

 cular apparatus is completely developed, the suboperculum being 

 very large, rather larger than the operculum, and forming the en- 

 tire posterior margin of the gill-opening. Interoperculum aa wide 

 and as long as the lower limb of the praeoperculum. The cubital 

 bone is long and styliform, leaving a very wide free space between 

 it and the humerus. The length of the abdominal portion of the 

 vertebral column is to that of the caudal as 1-6 : 1. The vertebrae 

 are as wide as long, contracted in the middle ; each abdominal ver- 

 tebra is provided with a pair of slender ribs on each side of its ven- 

 tral surface, and with another single one at the base of each neural 

 spine. The pubic bones are very broad, confluent, so as to leave 

 scarcely any free space between them ; they form a rather convex 

 triangular lamella in front, and are produced into a long styliform 

 process behind.
