Skeleton. — All the bones of the skull are very solid and strong. 

 The upper maxillary is styliform in its anterior half, and very broad 

 and spatuhforra in its posterior ; the intermaxillary is much shorter, 

 and has a broad plate-hke process at the descending branch ; the 

 posterior processes are rather short. There is a wide open notch 

 between the dentary and articular bones of the mandibula, and the 

 former has a longitudinal ridge at its outer side, with a shallow gi'oove 

 above ; pores and a muciferous channel arc scarcely visible. The 

 palatine bones are smooth, flat, horizontally situated, slightly bent 

 doAvnwards posteriorly. The praeoperculum is narrow, crescent- 

 shaped, with a very rudimentary muciferous channel : it is armed 

 with five spines, the lower of which are obtuse ; the uppermost is 

 the most pointed, and has an additional sjnne at its base. The oper- 

 culum is small, with two curved ridges, each terminating in a bundle 

 of small spines ; the suboperculura is joined to the operculum by two 

 processes, receiving between them the lower angle of the latter ; the 

 interoperculum is oblong. 



The tiu'binal bones are armed with several spines, one of which is 

 more prominent than the others : the praeorbital is irregiilarly shaped ; 

 several ridges radiate from a centre, and some terminate in spines : 

 the two other infraorbital bones, which form the bony bridge to the 

 praeoperculum, are rather broad, exhibiting at their surfs co clusters 

 of small spines ; the ascending branch of the infraorbital ring is 

 narrow. The ethmoid is intercalated between the principal frontal 

 bones, which diverge anteriorly ; each is pro\aded with an erect 

 process for the turbinal bones. Tlie anterior frontals form the 

 anterior part of the orbit, terminate superiorly in a spine, and emit 

 inferiorly a process, between which and the pra;orbital the groove is 

 situated, which is externally visible. The space between the orbits, 

 formed by the principal frontal bones, is rather broad and concave, 

 posteriorly covered Avith many small spines irregularly disposed ; two 

 of these spines are sitnafod :it tlio anterior corners of the quadrangular
