Genus AGITHALISCUS Cabanis, 1850. 
The genus Ayithaliscus contains a group of very small Titmouses 
with tails longer in proportion and more graduated than in Parus. 
There is no crest but the feathers of the crown are very long and 
full. There is no ventral band.

Zgithaliscus concinnus Gould, 1855. 
Our little Indian Tits hitherto known as erythrocephalus are 
only a geographical race of the Chinese concinnus, moreover the 
name itself cannot be used for this Tit as it is invalidated by 
Linné’s Parus erythrocephalus, x. ed. p. 191 (1758), and I have 
therefore had to give it a new subspecific name.
