Skeleton. — There are several strong crests on the upper part of 

 the skuU : the occipital crest is continued on to the anterior extre- 

 mity of the frontal bones ; the lateral crests are moderately elevated, 

 and proceed from the supercUiaiy margin. The basal poz-tion of the 

 brain-capsule is slightly compressed. The head of the vomer is flat 

 and ovate, Avith a patch of minute villifofm teeth. The palatine 

 and pterygoid bones are provided with bands of similar teeth. The 

 maxUlary and iutermaxillarj' are elongate and narrow ; the latter 

 has the posterior processes very short. The mandibula is rather 

 low, smooth, without ridges or a muciferous channel. The prse- 

 operculum has two very low ridges ; its inferior Umb is exceedingly 

 short. The operculum is higher than wide, iiTcgularly quadrang-ular. 

 The suboperculum is longer than the interoperculum. The supra- 

 scapula is suspended to the skull by two strong processes ; the sca- 

 pula is oblong. The humerus forms a deep cavity with the ulna ; 

 there is a wide slit between both bones ; the radius has a round 

 foramen. The pubic bones are rather small ; each is composed of 

 four lamellae. 



There are ten abdominal and sixteen caudal vertehrce, the length 

 of the former portion of the vertebral column being to that of the 

 latter as 1:1-8. Each of the vertebrae has a deep lateral impression. 

 The neural and haemal spines are rather strong, those of the abdo- 

 minal vertebra) being laterally compressed. There arc four spurious 

 interneural spines, each of which has an acute point directed for- 

 wards ; the posterior is the strongest, and its point can be observed 

 externally ; the other interneurals are rather feeble. The fii-st inter- 

 haemal is exceedingly strong, its lower half being bent forwards ; 

 the other intcrhffimals are dilated and transparent. The ribs are 

 well developed and rather stout.
