194 AN ATTEMPT TO DESCRIBE THE ANIMALS THAT MADE 



Divarication of the lateral toes, 100° ; of the inner and middle 

 toes, 50^ ; of the middle and outer toes, 50° ; of the middle 

 and hind toe, 120°. Length of the middle toe, 5 inches ; of the 

 inner toe, 3.75 inches ; of the outer toe, 4 inches ; of the foot, 

 6.5 to 7 inches ; of the heel, 2 inches ; of the hind toe, 2.75 inch- 

 es ; of the step, 16 to 23 inches; of the middle toe beyond the 

 rest, 2.5 inches. Distance between the tips of the lateral toes, 5.7 

 inches ; between the inner and middle toes, 3,9 inches ; between 

 the middle and outer toes, 3.9 inches ; between the middle and 

 hind toes, 6.8 inches. Versed sine of the backward curvature of 

 the hind toe, 0.2 inch ; of the inward curvature of the inner toe, 

 0.4 inch ; of the same in the middle toe, 0.6 inch ; of the same in 

 the outer toe, 0.2 inch. Angle between the axis of the foot and 

 the line of direction, 10° inwards. Distance of the middle of the 

 heel from the line of direction, 3 inches. Track shown, of the nat- 

 ural size, on Plate 8, fig. 3. 



Localities. — Horse Race, southwest part of Montague ; Chico- 

 pee Falls ; Cabotville ; Northampton ; Wethersfield. 



Remarks. — I am so well satisfied that the track which I de- 

 scribed in the Massachusetts Geological Report as the Ornithoidich- 

 nites divaricatus, having only three toes, is the same as that made 

 by the Ornithopus loripes, that I have united them. For when the 

 fourth toe is left out of the account, they do not seem distinct ; and 

 that toe, so frequently wanting, I do not regard as sufficient to char- 

 acterize a species. 



Plate 24, fig. 4, is copied and reduced from a specimen in my 

 cabinet obtained at Marsh's Quarry in Montague. It will give a 

 good idea of the relative situation of the feet when the animal 

 walked.
