This form is intermediate between the C. quadrivittatus and the C. ob- 

 soletus. The lateral baud is much wider than that of the former species. 

 A specimen was sent me from Mobile, Ala., by Dr. Joseph Corson, U. 

 S. Army, and it is therefore probably found in Florida, though it has 

 not yet been actually obtained there. A second specimen is in the Na- 

 tional Museum from Whitfield County, in northern Georgia. Two other 

 specimens — one from Mobile and one from Georgia— show the lateral 

 bands interrupted into spots posteriorly, and hence connect with the (7. 

 o. spiloides, D. & B. (C o. confinis, B. & G. Cope., olim). 



Coluber quadrivittatus Daudin. Common over the State. 



A series of twenty young of different ages from Georgiana show that 

 they are all spotted, and considerably resemble the C. o. spiloides in the 

 early stages, and that the lateral spots become first confluent into bauds, 

 and later the angles of the dorsal spots are produced so as to form the 

 two dorsal stripes. Later the dorsal spots disappear in most specimens ; 

 in a few individuals they remain. In the young the spots are consider- 

 ably more numerous than in the C. o. spiloides.

form and coloration. 

 Coluber guttatus sellatus, subsp. nov. 



This subspecies does not differ in any structural character from the 

 typical C. guttatus guttatus, excepting that the scales are in twenty-nine 

 instead of twenty-seven longitudinal rows. The value of this point is 

 uncertain, as but two specimens are known. The essential differences 

 are seen in the color. The head-bands, so conspicuous in the C. g. gut- 

 tatus, are wanting here, except the postocular, which is present, and is 

 black bordered above and below. The parietal band is indicated by 

 a black external border which extends to the edge of the parietal plate. 

 It is further faintly indicated by a shade which joins that of the oppo- 

 site side on the front of the frontal scute. A secoud character is seen 

 in the absence of lateral spots on the body, their places being clear pink 

 or yellowish, like the ground of the belly. The spaces between the dorsal 

 spots and those between the lateral clear spaces are gray dusted. The 

 scales at the superior edge of the lateral pale spots are sometimes black 

 bordered, partially outlining a lateral spot. This is most distinct an- 

 teriorly, where these borders form interrupted longitudinal lines. The 

 dorsal spots are red and have narrow serrate black anterior and poste- 

 rior borders. The spots are wider than in the G. g. guttatus, covering 

 nineteen and twenty-one longitudinal rows of scales, while in the former 

 they cover but from ten to fifteen rows of scales. The belly is tessel- 

 lated with black spots, as in C. g. guttatus, each spot covering the exter- 

 nal half of two or three gastrosteges. A delicate black line connects 

 them externally, running along the angle of the gastrosteges.
