Ophidia. 

 From tlie interior of Ecuador Mr. Wliymper obtained only two snakes, 

 belonging to two s^iecies, viz. Liojihis alticola and Leftoynathus nebulatus ; 

 and he observes : — " The most intelligent persons I could cpiestion declared 

 that snakes did not exist ; ami the surprise and cuiiosity which these two 

 specimens excited amongst the natives showed that they were rare." In his 

 paper on the reptiles collected by the Orton expedition Prof Cope mentions 

 no less than nine species of snakes from the " valley of Quito." This is in 

 contradiction with what Orton himself says : — " During a residence of nearly 

 tliree months in the Quito valley we saw liut one snake " (' The Andes and 

 the Amazon,' English edition, p. 107).
