542 Mr. G. L. Bates on the Reversed [Ibis, 



Median under coverts present on the cubitus and the 

 proximal lialf of the manus, the most distal one being 

 opposite the 5th manual remcx. These coverts are all 

 rather small, and one or two at the distal end of the row are 

 very small, with wholly downy vanes. The overlap of all is 

 the contrary one. 



Glaucidium sjostedti. One specimen examined, No. 5770. 



Major under coverts forming complete row, with twelve 

 on the manus ! there being also twelve remiges, eleven large 

 ones and the remicle ! ; overlap conforming on the cubitus 

 and distal half of the manus, contrary on the proximal half 

 of the manus. 



Median under coverts present on the cubitus and on 

 a little more than half of the manus, numbering six or 

 seven manual ones besides one at the carpal joint ; overlap 

 contrary. 



The two specimens of Owls examined, belonging to 

 different species and genera, differ in regard to the overhip 

 of the major under coverts, one having them all conforming, 

 the other having those on the proximal portion of the 

 manus contrary, in the manner seen so frequently among 

 the Accipitres. The two Owls agree, and differ from all the 

 AccipitreSj in the large number of median under coverts on 

 the manus, in this respect departing less from the normal 

 type than do the Accipitres. 



The abnormal number of manual remiges and corre- 

 sponding coverts in the specimen of Glaucidium is one 

 of several like instances found among birds of different 

 orders. 



Psittacus erithacus. One specimen examined, not saved. 



Major under coverts forming a complete row, with eleven 

 on the manus. From the wording of the note on this point 

 " an extra 11th one at the tip of the manus/' it is probably 

 intended that the remicle was wanting. Overlap of all of 

 this row conforming.
