Normal. Trace of median furrow 

 on nuchal. 



RC5 represented by 2 scutes. RM2 

 much reduced. 83 



Normal. 



Neural series of 7 elements, but 3 of 81 

 these (N4, 5 and 6) are incompletely 

 separated from one another.

Normal. I 



Normal. f 



Neural series of 8 elements, but N3| 82 



and N4 are not completely separated 



mesially. Nuchal with distinct furrow 



to left of median line, anteriorly. LCI 



wanting; LC5 represented by 2 scutes. 



D. 



Embryos and New'born. 



Eggs originally from 2 natural nests — but transplanted Into one artificial 

 nest. 



12 ? 12 I {Normal.) L marginals not thorough- 

 jly clear anteriorly. 



12 12 1 Supn'j' costal on each side, but LCI 

 wanting. No supn'y neural, but N4 

 with beginning (?) division on each 

 side so as to give usual adjustment. 



IS 13 Symmetry of LCI and 2 with RC2 



and 3 suggests that there is a supn'y 



costal on each side while LCI is wanting. 



Very abnormal: see text, p. 54. 



Normal. Slight median furrow on 



nuchal posteriorly. 



Normal. 



RCl merged in 2. 



Nuchal divided anteriorly. N6 show- 

 ing trace of seam, distinct on left pos- 

 teriorly. 5 ^'supram-arginals", 4 of 

 which are very minute. 



Much of the distortion observable in 

 the figure is due to contraction in the 

 preservative. 



12 12 LC5 represented by 2 scutes. "Cyclo- 



pean". 



12 12 Scutes abnormal anteriorly. "Cy- 



^clopean". 



12 10 Somewhat asymmetrical and mis- 



shapen. Nuchal with median seam 

 I anteriorly, continued posteriorly by a 

 I furrow.
