snake was about 5 feet long. In the collection made by Messrs. 

 Jackson and Lemuel Lee, July 15-November 1, 1912, we have a fine 

 specimen, ^he other specimen was secured in the fall of 1913 by 

 J. C. Bradley and Paul Battle. 



Coloration. — The coloration of the- larger specimen (No. 6,255) 

 is a pinkish-gray. In the cephalic end of the body there is on either 

 side of the back and sides a series of three rows of alternate spots 

 for a distance corresponding to four zigzag bands. The upper row 

 of each side is separated from the one of the other side by a reddish- 

 yellow band 3 scales wide which runs along the middle of the back 

 for quite a distance until the chevron bands begin. Then it con- 

 tinues along the back between the chevron spots almost to the anus. 

 This dorsal band shows better in the small specimen (No. 6,250). 

 Beyond the series of three rows of alternating spots on the neck 

 region come three bands which have not the lower row of spots 

 united with them. Then follows 18 zigzag cross-bands to the anus 

 and 4 on the tail, which is not completely black. The first of these 

 four does not completely encircle the tail as the subsequent ones 

 do. In the smaller specimen there are 5 black bands on the tail, 

 the first three not complete on the venter, and ahead of the anus 

 there are 26 bands, six of which are not wholly united. The median 

 point of the chevron is directed backward and the angle on the 

 sides points forward, the latter point usually being on the 7th-9th 

 row of scales. The black bands are 2 scales Avide and the ground- 

 color intervals 5-6 scales wide. Occasionally half black bands 

 appear with no counterpart on the other side. The venter is 

 lighter than the back, j-et heavily speckled with the ground color 

 of the back. These specimens well agree with the so-called cane- 

 brake form of the South. 



Dimensions and Variations. — The total length of the larger speci- 

 men is 118.7 cm., the tail 14.5 cm., or 8| in the total length, and with 

 14 rattles; anal entire; gastrosteges 178; the urosteges 22; scales 

 26-24-20; oculars 7; supralabials 14, the 4th the largest; infralabials 

 18 on the right side and 17 on the left side; two loreals. The smaller 

 specimen is 38.5 cm. long; the tail 3.3 cm., or llf in the total length; 

 anal entire; scales 27-(23-25)-21; orbital ring 8 on one side and 

 7 on the other side; infralabials 14. In both specimens there are 

 three rows of scales between the eye and the supralabials; the 

 larger specimen has the first row of body scales smooth. 



The natives described to us a large rattler as large as a diamond- 

 backed rattler and called it the "Siminole rattler," which we pro-
