POLYGLOT WABBLEB. 163 



added that Giova says the upjjer parts have a deeper olive green, 

 and less shading off into ash-colour, and the under parts a more 

 vivid yellow. It is found in the same places as icterijia. There is 

 no statement up to this time of its occurrence in Sardinia or in 

 Malta. It has the same habits as icterina. According to Gerbe the 

 eggs have in addition to the brown points some irregular brown 

 lines. I think Bonaparte's *S'. icterina, of the ' Fauna Italica/ refers 

 to this species." 



A fine male specimen of H. polyglotta, sent to me by Lieutenant- 

 Colonel Irby, and marked "S. Spain — Olcese," has the head, nape, 

 back, and upper tail coverts olive green. Wings and tail hair brown, 

 the secondaries slightly bordered with lighter brown, the primaries 

 and tail feathers more slightly so. Under parts bright yellow, slightly 

 shaded on the flanks with brown; the carpal border yellow. Under 

 parts of tail light brown. Second true wing primary the longest; 

 third shorter than fourth; first and fifth about same length, and 

 shorter than the fourth. Total length four inches and three quarters; 

 carpus to tip of wing two inches and a half; tarsus six tenths of 

 an inch. 



The bird figured is from a Spanish specimen sent to me by 

 Lieutenant-Colonel Irby, and was taken at Casa Vieja. The eg^ is 

 from the cabinet of Mr. Howard Saunders. I have a long series of 

 eggs of "Sylvia hypolais,^'' but I prefer one taken with the nest by 

 so good a naturalist as Mr. Saunders. 



I have had the benefit of comparing the skin figured of this bird 

 with a specimen marked "Tangier" sent to me by Mr. Dresser, and 

 one marked "Malaga" kindly sent me by Mr. Howard Saunders. 

 The former was fully half an inch shorter, and smaller in joroportion, 

 and the latter a quarter of an inch longer, and larger in proportion, 

 than the specimen figured. The Hypolais icterina, figured on the 

 same plate for comparison, is from a skin in my own collection from 

 Malta, and presented to me by Dr. Leith Adams. 



This bird has been figured by Mr. Dresser, in his Birds of Europe.
