With regard to the nomenclature of families, genera, 

 and species, I have adhered strictly to the ^^Interna- 

 tional Eules of Zoological Nomenclature," adopted by 

 the International Congress of Zoology.- As Dr. Stej- 

 neger remarks in his Herpetology of Japan, ^^ changes 

 in nomenclature necessitated by these rules, therefore, 

 must not be laid to any desire of the author to alter names, 

 but to the necessity of conforming strictly to the laws 

 now generally accepted by the working zoologists of the 

 world." 



DiKECTIONS FOR COLLECTING AND PRESERVING AMPHIBIANS 



AND EePTILES. 



When and where to collect. — ^While amphibians and 

 reptiles may be found occasionally in any season, spring 

 is the time for collecting. In a moderately cold climate 

 toads and salamanders may be looked for on the first 

 warm day, signaling the breaking up of winter. Eep- 

 tiles, as a rule, require warmer weather to rouse them 

 from their winter homes. 



Lizards, snakes, toads, frogs and salamanders are 

 mostly found under fallen logs and rocks. Salamanders, 

 frogs and toads are found in damp, shady places near 

 springs, creeks, and ponds, whereas snakes and lizards 

 are mostly found on the southern slopes of hill sides and 

 in or near water. 



Hoiv to secure the specimen. — Most reptiles and am- 

 phibians are easily caught by hand, but some reptiles are 

 either so quick in their movements or so shy that other 

 devices must be resorted to. Turtles may be caught with 

 hook and line, baited with raw meat or liver, or with a 

 dip net. Lizards and frogs may be shot with No. 12
