The coloi--pattern varies from a probably primitive, simple pattern consisting 

 of alternate whole and half cross-bars distributed along the entire length of the 

 body through the pattern consisting of whole, half and quarter bars, having an 

 incomjdete longitudinal series of lateral spots to a pattern having a very promi- 

 nent longitudinal series of dark lateral blotches with fine reticulations on the back. 

 Between these diflferent patterns all stages exist, so that they can be connected by 

 regular stejis. Those specimens inhabiting the lakes were found to possess a pecu- 

 liar color-pattern. This was derived from the primitive, simple pattern by sup- 

 posing the lower part of the whole bars to have become much broader than the 

 uj)per part, and then to have shifted backwards slightly.
