THE BATRACHIA OF NORTH AMERICA. 145 



to the P. Jiavipunctatus of Straucli, from California, to judge by the de- 

 scription given by that autlior. lit: states that the tail is shorter than 

 the head and body, that the digits are more acute, and the spots arc 

 wanting on the head and smaller on the back than on the sides. In all 

 these points it differs from the P. cvneus. 



I have seen but one specimen of this species. I took it at the mouth 

 of the Nickajack Cave, which is in the mountains at the junction of 

 the boundaries of tke States of Georgia, Alabama, and Tennessee. 



PLETHODON FLAVIPUNCTATUS Straucli. 

 Salaui., p. 71; Bouleuger, Cat. 13atr. Grad. Brit. Miis., eel. ii, 1882, p. 55. 



Palatine teeth in two very oblique series, converging backwards, sepa- 

 rated from each other by a slight interspace, not extending' outwards 

 beyond choaniie; parasphenoid teeth in two elongate patches in contact 

 throughout, widely sei)arated fronj the palatine teeth. Tongue very 

 large; posterior border free. Head rather long, with a median longi- 

 tudinal groove. Body cylindrical. Limbs as in P. fjhiUnosuSj but the 

 fingers more slender and more pointed. Tail cylindrical, a little shorter 

 than head alid body. Skin smooth; thirteen costal grooves. Black, 

 with large, irregular yellowish spots, more numerous on the sides and 

 on the upper part of the tail, smaller on the throat and belly, absent 

 on the upper surface of the head and the lower surface of the tail. To- 

 tal length, 117"">^. 



I have not seen this species, which is said by Br. Strauch to have 

 been obtained at IsTew Albion, Cal. It must be rare or of local distri- 

 bution. I have copied the above description from Boulenger's Cata- 

 logue of the British Museum, page 55.

This species, in general ai)pearance, proportions of body, etc., is very 

 similar to P. cinereus erythronotits, althougli abundant differences are 

 easily discoverable. The body, as in that species, is slender and de- 

 pressed, but the tail is slightly compressed at the middle, and more 

 strongly at the extremity. 



There are no apparent peculiarities about the head. The tongue is 

 elongated, elliptical, without posterior emargination. There are fourteen 

 costal furrows, or perhaps fifteen, if we include one above the axilla. 

 The distance from snout to axilla is contained rather less than three 

 times in that to groin. 



The digits are well developed ; more as in P. glutinosus. There is 

 little, if any, indication of web at their bases, the three terminal pha- 

 langes of the third and fourth toes being free. The third and fourth 

 toes are about equal. The outer toe is not more than half the second ;
