MEASUREMENTS 



(1912-1914) 



In 1 9 14 the following measurements were made on the 19 12 and 19 13 

 material : 



"The 44 specimens in length range from 12-24.5 mm., average 20.5 mm., 

 mode, 21 mm., the head is 4.75-8.5 mm., average 6.8 mm., mode 7 mm., 

 2.5-3.5 in the combined length of head and body; length of head to canthus 

 oris equal or slightly less than the breadth of the head at the same point, 

 rarely more than the head; the width of the head 3.75-8 mm., average 6.5 

 mm., mode 7 mm.; snout 2-4.75 mm., an average 3.8 mm., mode, 4 mm., 

 usually 1.5 greater than the diameter of the eye which ranges from 1.25-3.5 

 mm., average 2.6 mm., mode, 2.0 mm.; interorbital distance 1-2.5 mm., 

 average 1.7 mm.; interorbital distance equals eyelid; femur 6-12.75 mm., 

 average, 10 mm., mode 11 mm.; tibia 6.5-15.25 mm., average, 1 1.8 mm., mode 

 12 mm., in every case longer than the femur, usually 1.2 longer; body 1.8 

 longer than tibia; tarsus 4.5-8.5 mm., average 6.75, mode 7 mm., equal to the 

 head in length; rest of foot 4.75-15.75 mm., average 9.8 mm., mode, 11 mm., 

 longer than tarsus and averages slightly less than one-half the body (.47), 

 the range however being from .2 5-.9 of the length of the body, comparable to 

 the two extremes of Cope's analysis ('89, p. 325) for A. g. crepitans and A. g. 

 gryllus from north and south hut here in one locality. Rest of foot is not longer 

 than tibia but less: anterior limb 19.5-43.5 mm., average 33.1 mm., averages 

 1.6 times the length of the body; hind-limb to heel usually extends to or 

 beyond the end of the muzzle, rarely however, it reaches only to the eye."
