toe character separates them. The male R. virgatipes has a more pointed 

 head, much thicker legs, broader body and heavier darker ventral spots with 

 larger white interspaces. The dark speckled or spotted venters are typical of 

 transformation size in R. grylio, R. catesbeiana, R. clamitans and R. virgatipes 

 and as growth begins all come to have venters with larger dark spots with 

 larger light interspaces. In R. virgatipes the 2nd finger is equal to or less than 

 the first finger, in R. grylio the second finger is usually larger than the first 

 finger. 



GROWTH 



Of the 191 2 collection we wrote as follows: We have only one transformed 

 specimen which measures 44 mm. It was taken May 30, 19 12, from the 

 stomach of a snake. A specimen taken May 30, 191 2, on Honey Island 

 measures 53 mm. and doubtless represents a year old, while another taken 

 at the same time and measuring 72 mm. looks to be a two year old. Another 

 taken June 15, 1912 on Billy's Island measures 88 mm. or one from Floyd's 

 Island June 26, 1912, measures 88 mm. These doubtless are three year olds. 

 Three others taken in the same summer measure 96. 5-1 01 and easily are four 

 years old. These measurements 44, 53, 72, 88, 96.5-101 fairly well represent 

 the growth for 4 years after transformation. 



Some of our records for 192 1 follow: On April 24 and 25 we secured seven 

 specimens 100, 92, 95, 82, 50, 44, 44 mm. respectively, the last two at 44 mm., 

 being transformed individuals. They seem to fall into 4 groups 100, 92-95, 

 82, 44-50. From April 22-May, 6 sizes: one female 112 mm.; two males of 

 99 and 100 mm. respectively; two males 94-97 mm. respectively; one female 

 83 mm.; another 77 mm.; and two transforming at 37 and 39 mm. Those 

 taken May 10-23 f^l^ iiito three groups: one at 91 mm., the next group with 

 86, 77, 76 mm. respectively; the last group with 58, 62 mm. respectively. 

 June 15-20, 192 1, we have transformed example 46 mm. and one 73 mm. 

 Specimens taken July 11-19 are 38, 41, 43, 47, 61, 67, 67 mm. respectively 

 or of two groups. 



In 1922 from June 14-August 9 we took specimens 42, 49, 56, 60, 61, 69, 

 80, 84, 84 mm. in length. 



The 1921-1922 material seems to fall into the following groups: 

 (i) 32-49 mm., average 41 mm. tranformation. 



(2) 56-69 mm., " 62 . 5 mm. one-year-olds. 



(3) 73~86 mm., " 80 mm. two-year-olds. 



(4) 91-102 mm., " 96 mm. three-year-olds. 



(5) 107-115 mm., " 1 1 2 mm. four-year-olds. 



This species may reach 150 mm. Dr. Stejneger's type (U. S. N. M. No. 

 27443 is 125 mm. and U. S. N. M. No. 30951 is 148 mm.). 



Since this paragraph was written we have examined some specimens Dr. 

 Barbour has. Some of these are as follows 120 mm. cf, 125 mm. 9, 136 

 mm. d^, 143 mm. 9 , 161 mm. 9 and 161 mm. 9 . These are bigger than any 

 others in collections. The author, however, has also seen equally large indi- 

 viduals in the Okefinokee Swamp.
