AN ABNORMAL SALAMANDER. 



(Explanation of Figures.) 



E. B. Williamson. 



Mr. John Russi during the past summer collected a newt, 

 Diemyctelus viridescens, Raf. , n:ar Salem, Ohio, with a fifth 

 foot growing from the dorsal surface of the left thigh, as shown 

 in figure i. The newt is a young one, 48 millimeters in length. 



The left femur is slightly longer than the right, and is .shown 

 much enlarged at figure 2 in anterior view. Near its middle is 

 a section of cartilege which allows of the femur being bent 

 .slightly in any direction. Tendons from the fifth foot pass to^ 

 the femur at this point. Figure 3 shows a much enlarged draw- 

 ing of the skeletal elements of the foot from dorsal view. The 

 salamander w^as kept alive for some time but so far as was seen, 

 made no use of and exercised no control over its extra foot. I 

 am indebted to Mr. Russi for the privilege of examining this 

 interesting specimen which he has donated to the vSalem High 

 School Museum.

 sentatives of a number of other Ohio colleges and high schools. 

 Courses in General Zoology, Botany, Entomology, Invertebrate 

 Morphology, Embryology and Ornithology were given. Collect-
