firmly attached to the opercle. The siiprascapula is anchylosed to 

 the bones of the skiill ; the upper and lower portions of the humerus 

 axe dilated, and there is a very narrow cleft between the radius and 

 humerus ; the former does not extend so far downwards as the hu- 

 merus. The coracoid is much stronger than the ribs, and composed 

 of two bones. The pubic bones are well developed, and do not leave 

 a free space between them ; each is composed of three lamellae, the 

 inferior of which is the broadest, having the edge swollen. 



There axe ten abdominal and twelve or thirteen caudal vertebrce, 

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

 that of the latter as 1 : 1-33. All the vertebrae are very short, with 

 the neural and haemal spines of moderate strength ; the haemal of 

 the first caudal vertebra, however, is much stronger than the others. 

 The intemeurals of the spinous dorsal fin are dUated and provided 

 with prominent ridges, whilst those of the soft dorsal are very feeble; 

 the first intemeural bears two dorsal spines, and has a pointed pro- 

 cess anteriorly, which extends on to the occipital crest. The inter- 

 haemal of the anal spines is straight, and dilated at its extremity ; it 

 is firmly attached to the first haemal, which also supports the inter- 

 haemals of the first three anal rays. The arrangement of the other 

 interhaemals is the same as in Micropteryx chrysurus.
