84. V. sagittiros'tris Roths. 



Genus OREOMY'^A Stejneger. 



Under mandible straight, or at least not perceptibl}- curved; plumage soft and 

 fluffy; tarsus covered in front with four, five or six scales ; nasal operculum slightly 

 overhung at the base by tiny feathers; tip of the wing formed by the third, fourth, 



"Mr. Rothschild (Avifauna of taysan. Part III., page 129) gives Oreomy-a peikimi as a new species from Hawaii, describing it as fol- 

 lows ; '• Adult male : Above light olive green (Ridgway Nom. Colors. PI. X., No. j8), brighter on the rump ; quills black edged with oil green; 

 below olive yellow: vent greenish white ; thighs dirty white ; under wing coverts white with a yellow tinge : lores black ; iris dark brown; 

 legs and feet greyish brown ; soles of feet yellowish-flesh color ; upper mandible dark brown with paler base ; lower mandible grey. Total 

 length about 5.5 inches ; wing 2.6. tail 1.7, tarsus 0.S5, culmeii 0.63. One male, Puulehua, Hawaii. .September 2.5, 1891." In commenting on the 



specimen in the Tring Museum Mr. Rothschild states that the "remarkable specimen has a long but straight bill The coloration is 



that of Chlorodrepaiiis 2'iretis and that it might be a hybrid between Ommn'sa tiiaim ajid ChhindrepauU viinn." The B. P. Bishop 



Museum series, embracing many recently colleifted specimens, show vireiii with beaks approaching the straight form, though none that are 

 to be confounded with the Oreomyza type ; while fine old males of Oreomyza viana are much more highly colored than has been usually sup- 

 posed. The only charadler in Mr. Rothschild's description which seems to be of specific value, when compared with the Museum series, is 

 the length, which is given as almost an inch longer than the average of either maiia or vhens. Since the author fails to call attention to this 

 point it may possibly be a typographical error. Mr. Henshaw informs me he has taken nothing that conforms with the description, and as 

 Mr. Perkins has not met with the bird the status of the species is somewhat doubtful. 



"At the suggestion of my friend Professor H. W. Henshaw we have made a careful study of the alcoholic material m the Museum, and 

 find the tongue of fian'a to be distin(5i;ly tubular in form ; a fact which alone would at once remove it from the genus Oreomv^a, and which at 

 the same time indicates its affinity with the tube-tonged Chtoiodrefnuiis group. My observations of the bird alive, while collecting on Kauai, 

 convince me that its habits are those of the C/ilurMlirpaiiis rather than of Oreomyza.
