developed. Tail more compressed than in S. maculicaudus. Length 

 of tail 1.9 times longer than head and body. 



Color. — Spelerpes stejnegeri differs from both S. maculicaudus and 

 8. longicaudus in color. The back in 8. stejnegeri is raw sienna with 

 many dark spots, coalescing in places and irregularly arranged in two 

 series on either side of the median line. Some specimens have these 

 spots on the side of the back more numerous, forming sometimes nearly 

 a stripe. The median line, and a streak from the eye back to above 

 the hind limbs, as well as the top of the tail, are free from spots or 

 have very few. Sides of the tail with marbling of sienna. Top of feet 

 marbled like the sides. Belly yellowish white, sometimes with a few 

 light dots. 



Size. — From end of snout to vent 46 mm.; from vent to end of tail 

 88 mm. Total length 134 mm. 



Habitat, — It is found in the Ozark Plateau, becoming 

 more numerous toward the south. Missouri localities : — 

 Eockhouse Cave, Barry Co., Wilson's Cave, near Sar- 

 coxie, Jasper Co., Fisher's Cave, near Springfield, Greene 

 Co., Green's Cave, near Sullivan, Franklin Co., near 

 Marble Cave, Stone Co., Pineville, McDonald Co., Jerome, 

 Phelps Co., and Leasburg, Crawford Co. 



Habits. — This species is also a twilight species, as it 

 is mostly found under slabs of rock at the mouth of caves 

 and never a very great distance into the cave. At Wil- 

 son's Cave — a small cave — I found this salamander among 

 the rocks which dam the little creek at the mouth of the 

 cave. When I visited the cave there was no running 

 water but a little pool just inside the cave. I managed 

 to capture a few small larv^ae. Near the residence of Hon. 

 Thurman S. Powell, near Marble Cave, I found a good 

 many of these salamanders in holes under rocks at the 

 bottom and sides of the caves, where they were clinging 

 to the rocks. At Green's Cave, Franklin Co., which has a 

 large portal-like entrance, I caught some of them under 

 rocks in the water, but not further back in the cave than 

 daylight penetrated. Those from Jerome and from near 

 the Onondago Cave were caught under rocks on the shady 

 side of the ravines. Those at Pineville I fished out of a 

 little spring on the side of a hill in an open pasture. I do
