mandible, and in none of the series (8 males, 3 females) is the white 

 forehead less than .15 in. in width. 



Length (skin), 3.75 in. (95.2 mm.); wing, 2.25 in. (57.2 mm.); 

 tail, 1.75 in. (44.4 mm.); culmen, .38 in. (9.6 mm.). 



According to Mr. Ferry, the species is common on the island. 

 Many nests were found, but all were empty. 



Family Miiiotiltidse. 



Dendroica ruficapilla rufopileata Ridgw. 

 4 specimens, all males; common. 



Family Mimiclse. 



Mimus gilvus (Vieill.). 



15 specimens, n cT, 4 9 ; common. 



Specimens from Tortuga vary in size of bill and coloration and 

 are apparently intermediate between gilvus and rostratus, and might 

 equally well be referred to either. For convenience I have consid- 

 ered birds from Tortuga and Margarita to be gilvus. 



BLANQUILLA ISLAND. 



The Island of Blanquilla, or Blanca, as it is sometimes called, is 

 situated about 40 miles north of Margarita and 85 miles east of Or- 

 chilla. It is six miles long and about three miles broad at its widest 

 part. The interior of the island is broken with ravines, most of 

 them wooded. There is a considerable growth of trees on the western 

 end and some groves of palms. Large areas are covered with grass. 



"A Venezuelan leases the island and conducts a goat ranch. 

 About his estate we found all the land birds occurring on the island 

 except the large parrot. Vegetation is far more luxuriant and vig- 

 orous on this island than on any previously visited, although it is 

 still of a semi-arid character." (Ferry.) 



This island had previously been visited by Mr. Percy R. Lowe, 

 who has published the following papers concerning its ave fauna:
