 succeeded in reaching the woods back of the town of Catbalogan in 

 Samar, in 1888 Three males average, 253 in length; wing, 125; tail, 

 102; culmen, 31; tarsus, 17; middle toe with claw, 23. A female, length, 

 257; wing, 123; tail, 103; culmen, 31; tarsus, 16; middle toe with 

 claw, 23. Bill, legs, feet, and nails black; iris red." {Bourns and

 nao (Bourns & ^Yorcester) . 



Adult. — Very similar to Irena cyanogastra, but the upper back and 

 mantle black instead of deep blue. Iris cherry red; bill, legs, and nails 

 black. Length, about 230. A male from Basilan measures : Wing, 121 ; 

 tail, 102; culmen from base, 27; bill from nostril, 19; tarsus, 18. A 

 female measures: Wing, 118; tail, 98; culmen from base, S8; tarsus, 20. 



"This fairy bluebird is a strictly deep woods form and a very fine 

 singer; it is rather shy, but can readily be procured, as it never remains 

 silent for any length of time. It is often difficult to distinguish from 

 Dicrurus striatus when seen at a little distance, unless its tail is in plain 

 view. All of the Philippine Irenidce are difficult to collect in good con- 

 dition. They have very thin skins and loose feathers, and frequently 

 ruin themselves in falling. They all feed on fruit. Ten males from 

 Basilan average: Length, 236; wing, 120; tail, 98; culmen, 30; tarsus, 

 18; middle toe with claw, 22. Eleven females, length, 229; wing, 116; 

 tail, 96; culmen, 30; tarsus, 17; middle toe with claw, 22." {Bourns 

 and Worcester MS.)
