SAGMATIAS AMBLODON Cope. 



(Plate 30, iig. 1.) 



Only the skull knowu. 



Beak one half the length of the entire cranium, and one-half as broad' 

 at the base as long. Temporal foss;iB large and rounded. Interniax- 

 illa3 flat ; they occupy rather more than one-half the breadth of the beak 

 at the middle. Pterygoids short, scarcely or not touching in the median 

 line. 



Teeth p (much worn in the type, but probably originally conical and 

 acutely pointed). 



Mmsuremcnts of the type skull. — Total length, 37.2™; length of beak, 

 18.5"" ; breadth of beak at base, 9.7"" ; at its middle, 0.2 '" ; length of 

 tooth line, 15.7""; breadth between orbits, 16.7'™; temporal fossre, 7.9 '"x 

 .G.l™. 



Habitat unknown. 



9. FEHESxl Gray. 



Rostrum half the total length ; very broad. Rostral portion of inter- 

 maxillaj flat; their inner margins separate throughout. Mandible deep 

 between the angle and coronoid process, slender in the center of the 

 •rami and obtusely keeled at the symphysis. Teeth few and large, 11 to 

 12. Tooth-line extending along only the anterior two thirds of the 

 rostrum. 



Skeleton and exterior unknown. 



FERESA INTERMEDIA Gray. 

 (Plate 30, tig. 2.) 



Exterior unknown. 



Teeth ^ to j^. _Skull small but massive. Rostrum one-half the total 

 length; very broad. lutermaxilhie moderately expanded proximally ; 

 very broad distally (they occupy rather more than two-thirds of the 

 breadth of the rostrum at its middle) ; rostral portion flat (a wide space 

 between their inner edges, in the median line of the rostrum, in which 

 the vomer is visible nearly to the end of the rostrum). Superior nares 

 small; the transverse diameter less than one-fourth the breadth across 

 the orbits; narrowed antero-posteriorly by the sloping forward of the 

 mesethenoid. 



Teeth ver^^ large ; upper tooth-line occupying only about two-thirds 

 the length of the beak. Orbits short. Temporal Ibssie moderate and 

 squared. Mandible deep between the angle and coronoid process, slen- 

 der opposite the middleof the tooth-line, and obtusely keeled at the sym- 

 physis, as in Lafjeiiorhxjnchus electra.
