The coloration resembles that of iS. biUneata. There is a broad red- 

 dish or browuish yellow dorsal stripe from head to eud of tail, bounded 

 oil each side b}^ a narrow dark line extending from the eye, fading 

 gradually off below. The sides are closely dotted or mottled with 

 brownish dots, the dark line referred to beiug merely a closer arrange- 

 ment of the dots. The under parts are whitish in ah^ohol, finely mot- 

 tled or dotted like the sides, but less closely and more iiidistiuguishably. 

 The median line of the belly is generally immaculate. There is almost 

 always a narrow light line on the side from the fore to hind legs. 



The light dorsal stripe is generally more or less dotted with brownish, 

 sometimes with a tendency to a median stripe. 



In one specimen the sides are distinctly dotted finely with white. 



This species was referred to Batrachoseps of Bonaparte by Professor 

 Baird, without probably Laving seen the t^^pe of the latter, no doubt 

 on the faith of Bonaparte's erroneous description of the tongue of the 

 same. It is evident that the two species ought not to be regarded as 

 congeneric, since the B. attenuatus turns out to be more nearly allied 

 to Hemidactylium than to Spelerpes. ' 



The known range of this, one of the smallest of land vertebrates, is 

 from middle North Carolina to the border of Texas, including Florida,
