Harporhynchus crissalis (I, 47). Captain Bendire found this species breeding abundantly near Tucson, Arizona (See Coues, Am. Nat. VI, June, 1872, 370). The eggs in all instances were similar to those described as found by Dr. Palmer, unspotted, and in size, shape, and color, hardly distinguishable from the eggs of the common Robin (T. migratorius). They are of an oblong-oval shape, rounded and nearly equal at either end, and measure 1.10 inches in length by .75 in breadth.

Harporhynchus redivivus (I, 45). The accompanying cut, showing the extreme anatomy of the species, was omitted in its proper place.
Mimus polyglottus (I, 49). Mr. C. E. Aiken has obtained this species in El Paso County, Colorado.
Saxicola œnanthe (I, 60). Mr. C. J. Hampton obtained a specimen of this bird at Junius, Seneca County, N. Y., on the 9th of September, 1872. Professor Newton suggests, by letter, as an interesting problem, the route by which this species reaches Alaska in its migrations. It is not known to occur near the Sea of Ochotsk, has not been found on the Lower Amoor, and probably does not occur farther eastward than the Baikal Mountains. It has never been noticed in Japan or on the coast of China. It must therefore be very nearly certain that it cannot take that way to Alaska. Sundeval states that it is found in Kamtschatka, but this Mr. Newton questions, as no authority is given for this statement. The only alternative is to assume a route via Greenland, in this, perhaps, in a measure indorsing Petermann’s suggestion that Greenland extends across the pole nearly to the Asiatic coast and to Alaska.
Sialia mexicana (I, 65). This species has been obtained in Western Iowa by Mr. Atkinson.
Regulus calendula (I, 75). We present the outlines of bill, feet, wings, and tail, omitted in their proper place.
