DUNN: AMPHIBIA CAUDATA. 469 



The specimens from Georgia are very close to E. guttolineata. They 

 differ from typical E. lojigicauda: — 1st, in having the median Hne of 

 the tail unspotted, 2d, the bars on the tail are fused dorsally and 3rd, 

 there is a single, somewhat run together, line of spots in the middle 

 of the back instead of a generally spotted back. The physiognomy 

 is that of E. guttolineata. 



The only real differences between them and E. guttolineata are that 

 the belly is unpigmented, the middorsal stripe is somewhat broken up, 

 and there are distinct evidences of bars on the tail. As these speci- 

 mens are without definite locality, I do not make E. guttolineata a 

 subspecies, but there can be no doubt that they intergrade, and that 

 this intergradation takes place in Georgia. It is gratifying that my 

 prediction as to the close relationship of these two forms is demon- 

 strated. 



75. EURYCEA MELANOPLEURA (Cope). 



Mo.: Jasper County, Wilson's Cave, 2,551 (paratype of E. (Spelerpes stejne- 

 ^m Eigenmann) ; 4,609; 4,610; Stone County, 2,538; 2,780(2); 3,776; 

 3,777; Stone County, Reed's Spring, 3,486.— Tex., 244. 



This species is very close to E. longicauda, differing from it in the 

 indistinctness of the bars on the tail, and in the arrangement of the 

 pigment on the back so as to leave the median line unspotted. Traces 

 of this arrangement are sometimes found in young E. guttolineata 

 where the dorsal stripe is divided in the middle. 



Comparison of all available material of this species including the 

 type, with similar material of the so-called Spelerpes stejnegeri Eigen- 

 mann, makes it perfectly plain that the former is the young of the 

 latter. Cope's name has years of priority over Eigenmann's. 



Hurter in various publications records this species, under Eigen- 

 mann's name, and as E. longicauda from different localities throughout 

 Missouri. He records them in a way that indicates an overlapping 

 distribution. However, as these two species are very closely related 

 and as Hurter was collecting before E. stejnegeri was described, and 

 as neither this collection, nor the National Museum, which includes 

 Hurter's own collection, has the two from the same place or from 

 places which would mean overlapping of ranges, it is probably safe 

 to regard them as vicarious species. Specimens of E. longicauda are 

 in collections from two counties, St. Louis and Jefferson. Franklin 

 county is the farthest east for E. melanopleura.
