 growth of bright crimson filaments appeared on the gill stalks, 

 and the usual rich-hued, feathery tufts were present on each side 

 of the head within a month. The writer has not only noted that 

 specimens of Ncctiiriis soon die unless provided with steadily 

 flowing w^ater, but that an abrupt transfer of the animals from 

 very cold water to that of a higher temperature, or vice versa, is 

 often fatal. He would suggest that care be taken with examples 

 received in the w^inter months. Instead of taking them directly 

 from the shipping tank and placing them in an indoor aquarium 

 it is advisable to take the temperature of the water of both recep- 

 tacles, and, before the transfer is made, effect a slow change in 

 the medium in which the specimens have arrived until it corre- 

 sponds in temperature with that of the exhibition tank. 



Among jNIr. Sanborn's photographs are several of the showy 

 California Newt (Dieinyctylns torosus). A number of represen- 

 tatives of this species are on exhibition. As they are cannibalistic 

 — greedily devouring examples of the Common Newt (D. virides- 

 reiis) of the Eastern States — they are kept in a tank by them-
