908 THE SECRETARY ON ADDITIONS TO THE MENAGERIE. 



and of which only seven survived, two males and five females, 

 reproduced their species on September 29th and 30th, the adult 

 coloration of the males appearing only on October 7th and 16th. 

 When we consider the fact that these fishes, owing to the warmer 

 tanks being already occupied, were kept at the low average 

 temperature of 65°, we must conclude that, like their growth, the 

 period of gestation must have been slow, and that the male 

 undoubtedly bred at least a month before acquiring its full 

 secondary sexual characters. 



A parallel case is well known in the male Salmon, which 

 occasionally becomes sexually mature in the parr condition, 

 while the Wrass (Coris jidis) and the Dragonet {Callionymus 

 lyra) have been observed by Mr. E. W. Holt also to become 

 sexually mature prior to having fully developed their adult 

 charactei"s. In the two latter cases, however, the question is 

 one of degree only, the characteristic male livery not being 

 entirely absent, as in Girardinus.
