mode of locomotion, which was also observed in B. galeanae. The tip 
of the tail is narrowed and somewhat attenuated and is differently 
colored from the remainder of the tail. The tip of the tail and per- 
haps the coloration appear to be linked with a special locomotor 
adaptation. As the animal moves forward in normal, unmolested 
walking, the tail is held straight back except for the terminal half inch 
or so, which is flipped forward with each step made by one particular 
lee. Upon being swung forward into position, the tip is placed on the 
ground, and then by straightening and pivoting on the tip the tail 
pushes the body forward as another step is taken. Unfortunately we 
did not observe whether the pushing movement of the tail is synchro- 
nized with one of the forelegs or with one of the hindlegs, but we sus- 
pect with the former, since the forelegs are somewhat weaker than the 
hindlegs. 
BOLITOGLOSSA GALEANAE Taylor 
Bolitoglossa galaenae TAYuoR, Proc. Biol. Soc. Washington, vol. 54, July 31, 1941b, 
pp. 83-85 (Galeana, Nuevo Leén). (Specific name misspelled by typograph- 
ical error; should read galeanae.) 
Nineteen paratypes were collected 15 miles southeast of Galeana, 
Nuevo Leén, October 13-14, 1989 (U.S.N.M. Nos. 119642-119658 
cataloged). These were found in a semiarid region of little vegetation, 
rocky, barren soil, small bushy shrubs, and cactus. The area is so 
completely unlike salamander country that the discovery of the sala- 
manders came as a complete surprise. The specimens were found 
under stones in company with Tantilla wilcoxt rubricata, Salvadora 
lineata, and Syrrhophus smithi. The collecting was done during and 
shortly after a rainstorm in the middle of a week of continued cloudi- 
ness and intermittent, drizzling showers. Most of the year the soil is 
obviously very dry. Since there are no bromelias about, it would be 
very interesting to know how the salamanders manage to survive the 
unfavorable climate. 
This form belongs to the B. cephalica subgroup and is probably the 
largest species.
