* The identity of N. unicolor with N. miarensis has been confirmed by M. 

 Grandidier, who, in reply to a communication from Dr. Giinther (kindly made 

 at my request), states that this species was described by him under two names 

 in consequence of a mistake made by the editor of the ' Eevue et Mag. Zoologie.' 

 The original description of N. miarensis was taken by M. Grandidier from a 

 much injured specimen, and the MS. was sent from Madagascar to the editor 

 at Paris. Soon afterwards, having obtained another specimen in good con- 

 dition, he wrote out a second description, changing the manuscript name to 

 N. unicolor as being more suitable, and forwarded it to the editor with a request 

 that if his previous communication had not been published, the MS. might be 

 destroyed and the second description be printed instead. When his second 

 letter arrived the contents of the first had been published, but the editor, not 

 quite understanding what he wished to be done, published the second descrip- 

 tion al.'io.
