Skeleton. — The upper sm-face of the skuU is nearly fiat between 

 the eyes, exhibiting some low ridges and shght grooves ; the occi- 

 pital crest extends on the upper side of the skull as far only as 

 the posterior margin of the orbit ; it is rather low, and not elevated 

 above the level of the skull. The basal part of the maxillary is 

 somewhat flattened ; it does not become very broad at its posterior 

 extremity, where it exhibits a concave anterior margin. The inter- 

 maxillary has the posterior processes of moderate length, and a flat 

 crescent-shaped expansion at its posterior half. The prgeorbital is 

 quadrangular, oblong, t^dce as long as high ; the posterior part of 

 the infraorbital arch is narrow ; the second and thu-d of the bones 

 have an excavated plate witliin, reaching into the inside of the orbital 

 groove. The operculum is armed posteriorly with two points, sepa- 

 rated from each other by a groove ; the superior is short, without 

 corresponding bony ridge ; the inferior is acute and stronger, and 

 forms the termination of a bony longitudinal ridge situated at the 

 inner side of the opercidum. The limbs of the praeoperculum are 

 directed vertically towards each other, but the angle itself is 

 roimded ; the posterior margin is exceedingly finely serrated, the 

 inferior more coarsely; the angle is distinctly striated, the striae 

 tenninating in small spinous teeth. There is a bony elevated ridge 

 within the margin of the prseopercidum : it shows no denticula-
