556 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxxv. 



The single observation made on their feeding habits is of interest. 

 Human feces near the mouth of the cave formed a favorite feeding 

 place for these salamanders. Two were captured, and an examina- 

 tion of their stomachs showed that the animals had been feeding on 

 small adult flies and dipterous larva?, which were abundant in the 

 refuse. At this point I could not see the animals without a light, 

 even when they moved and after my eyes had been accustomed to the 

 twilight. It would have been impossible for the human eye to dis- 

 tinguish flies in such a place. Others of the species taken in better 

 light in the Hamer Cave had also been eating flies. The eyes do not 

 appear to be in any measure degenerate. 



An individual kept in captivity for some time refused to eat earth- 

 worms, myriapods, or small beetles placed in a glass jar with it. 



A specimen taken from the Hamer Cave on July 22 differs some- 

 what in appearance from most individuals of this species that I have 

 seen. The body is much distended with eggs. In life the ground 

 color is a very deep orange with the black spots large, sharply defined 

 and round; the tip of the tail is entirely black for about 10 mm. 



Another specimen has the ground color similar to the above, but 

 the back is marked with large irregular black blotches, indistinctly 

 outlined and often confluent, so that the orange forms scarcely more 

 than a reticulation. On the tail the black spots are smaller and they 

 do not extend as far down the sides as in most individuals. Still 

 another individual is pale yellow, with medium-sized black spots on 

 the back, and the tail covered with many small black dots. 



Total length. 153 mm.; snout to axilla, 21; snout to groin, 57. 

 Costal grooves, 13. 



SPELERPES BISLINEATUS (Green). 

 TWO-LINED TRITON. 



Seen only along the stream leading from the Shawnee Cave, where 

 it was abundant. Usually it was found hiding under submerged 

 rocks, but once or twice was seen out of the water. Adults were to 

 be -cen there throughout the year, but no eggs or very young larva 1 

 were found. Larvae about 25 nun. in length were found in January 

 in a little spring-fed tributary to this stream. 



One of these young killed on March 12 is 29 mm. long and the 

 gill- are short, although the tail is still strongly keeled. The pig- 

 ment spots have not yet segregated into unbroken bands, but form 

 a row of small blotches along each side of the back. The median dark 

 stripe is scarcely indicated. The <ides are uniformly sprinkled with 

 specks of brown pigment, as are the limbs and head. By March 

 25 one of the larvae had transformed. An adult female taken on 

 March ■!'.) had the ovaries distended with eggs which appeared to be 

 nearly ripe.
