Adult male (tuinter). Differs from D. minor in having the whole 

 of the under surface of the body and the under tail-coverts pure 

 white, the latter being occasionally uniform, but more often with a 

 few small spots of black ; with fewer black bars or transverse spots 

 on the lateral tail-feathers ; the lower half of the back and the 

 rump almost spotless white, with only a trace of bar-like markings 

 of black ; the white bars on the wings broader ; the measurements 

 are also greater. In other respects it resembles D. minor. Total 

 length 6-5 inches, culmen 0-7, wing 3-75, tail 2'45, tarsus 0-6 ; toes 

 (without claws) — outer anterior U'33, outer posterior 0*43, inner 

 anterior 0*3, inner posterior 0'2. 



Adult female {winter). Differs from the adult male in the 

 absence of red on the crown, this being for the greater part white, 

 the outer edge, likewise the occiput, being black as in the male. 

 Total length 6*2 inches, culmen 0-7, wing 3'75, tail 2-G, tarsus 0'58. 



In summer both sexes have a few black striations on the sides of 

 the chest and on the thighs, and the white of the back is more 

 barred with black ; the under surface of the body, although white, 

 is scarcely so pure. In this plumage they more resemble northern 

 examples of D. minor in winter.

Adult male. According to Radde the small Spotted Woodpecker 

 of the Caucasus differs from D. minor in having only four bands of 

 white on the wings (when closed) instead of five, as in the latter 

 species ; the dimensions are also less, and are given by Radde as 

 follows : — Total length 128 millim., wing 83, tail 55, culmen 14, 

 tarsus 15. 



Adult female. Has no red on the top of the head. Total length 

 126 millim., wing 82, tail 55, culmen 12, tarsus 15.
