Note Since the above was written, a specimen collected last summer and consist- 

 ing of the squamosal, jugal and postfronal ot the right side, with the front margin of the 

 orbit completing the circumference of the eye-opening, proves to be referable to S. albert- 

 ensis. This specimen was obtained from the Belly River formation, about four miles up 

 stream from where the type was discovered. In it a narrow, flat process is seen to proceed 

 backward from the jugal below the lateral temporal fossa and to overlap the forwardly 

 directed process of the squamosal as far as the middle of the lower margin of this opening. 

 This process was not at first recognized in the type, but is now clearlv seen. It has been 

 broken from the main portion of the jugal, but is in place between the posterior termina- 

 tion of the quadratojugal and the lateral temporal fossa. In all particulars this second 

 specimen fully agrees with the type. Above the eve a similar smooth surfaced depression 

 marks the position of the supraorbital horn-core and the free margin of l he post frontal 

 fontanelle and supratempor - al fossa is present. 



Explanation of Plates. 



Plate X. Lateral aspect of type of Styracosaurus albertensis, 

 one-twelfth the natural size. 



Plate XI. The same specimen viewed from above and 

 similarly reduced. 



Plate XII. Restored outline of the same specimen, viewed 

 from the side and similarly reduced.

BIRD NOTE. 



Pilot Mound, Max., Sept. 18. My opposite neighbour lias 

 a nest of Spinas tristris, the goldfinch, with two half-fledged 

 nestlings out of a clutch of four eggs. Two of the eggs did not 

 hatch cut. I wonder whether Air. Norman Criddle ran beat 

 this for a record of late nesting in Manitoba. Usually we have 

 frost enough by Sept. 15th to kill all half-hardy plants in the 

 garden, but this year we have escaped frost entirely, up to date.
