the tongue of nestling Dryoscopus guttatus (fig. 25, a) should 

 be shown perfectly plain. The twin spots only commence to 

 show after the young have left the nest, and it is some weeks 

 more before they attain even the strength shown in fig. 25, b. 

 Having mentioned fig. 15, I may add that, in view of a 

 recent observation, the possibility of mimicry between 

 mouths of Pycnonotus and Hyphantorras, guardedly hinted 

 at in pp. 284-5, probably need not be considered at all. 



I would like to compliment Mr. Gronvold on his success 

 with a plate of a kind he has probably not undertaken before 

 and which he had to execute under the difficult condition 

 of shrunken spirit-specimens, with notes and rough sketches 

 by a person too far away to be readily consulted." 



Two new names given to British Birds. — The July number 

 of ' The Auk ' (p. 346) has a note that, in a recent number 

 of ' Falco,' the organ of the eccentric Otto Kleinschmidt, 

 there are descriptions of the British races of Passer domes- 

 ticus and Strix alba under the new names Passer hostilis and 

 Strix hostilis. The author, O. Kleinschmidt, states that his 

 subspecies will proHably have a hostile reception in their 

 uative country, and explains that he does not name them in 

 the interests of British Ornithology but iu accordance with 

 the thoroughness of German science !
