Text Figures 



Note. — Numbers in parentheses following titles of figures, and usually accom- 

 panying the figures in the text, are those of the specimens in the Museum of 

 Vertebrate Zoology from which the drawings were made; figures drawn from 

 specimens in private collections have numbers followed by initials of owners 

 (e.g., 209 H.SS.). All figures natural size except as noted.
