Fig. 1. Desmognathus santeetlah embryo at four different Harrison developmental 

 stages: (A) stage 25, (B) stage 35, (C) stage 40, (D) stage 45. Note spherical 

 orientation of embryo, even at late developmental stages. Bars = 2.0 mm. 



Egg laying is not synchronous in plethodontid salamanders, 

 and this precludes collection of a large number of plethodontid 

 clutches at early stages of development. Therefore, I collected 

 clutches at various stages of development. To ensure that intraclutch 

 variation did not vary with development, a Wilcoxon's matched-pairs 

 signed-ranks test was conducted on 12 D. santeetlah clutches to test 

 if stage of development significantly influenced CV. Coefficients of 

 variation were calculated for two developmental stages (stage 45 and 

 an earlier stage, ranging from 9 to 41 for the clutches in question) 

 for each clutch, and no significant difference was found in CV due
