SAGMATIAS AMBLODON Cope. 

 (Plate 30, iig. 1.) 



Only the skull known. 



Beak one half the length of the entire cranimu, and one-half a.s broad 

 at the base as long. Temporal fossa^. large and roimded. Interniax- 

 ilhii flat; they occiip}' rather more than one-half the breadth of the beak 

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

 line. 



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

 acutely pointed). 



Measurements of the type skull. — Total length, 37.2 ""; length of beak, 

 18.5""; breadth of beak at base, 9.7""; at its middle, G.2'"'; length of 

 tooth line, 15.7'"'; breadth between orbits, 1G.7""; temporal fossa?, 7.9 '"x 

 G.V". 



Habitat unknown. 



9. FEKESA Gray. 



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

 maxillai liat; 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. Tee'th 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 |^. Skull small but massive. Rostrum one-half the total 

 length; very broad. Intermaxilhe moderately expanded [»roximally ; 

 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-iwsteriorly by the sloi)ing forward of the 

 mesethenoid. 



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

 the length of the beak. Orbits short. Tem[>oral fossiii moderate and 

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

 der opposite the middle of the tooth-line, an d obtusely keeled at the sym- 

 jihysis, as in Lagcnorhijtichus elcctra.
