and under tail-coverts. This name is equivalent to Dissoura, 

 applied by Dr. Cabanis in 1850 to the Old- World Ciconia 

 episcopus, so Dr. Reichenow tells us^ who, however, uses the 

 latter name in a subgeneric, and not a generic sense. We 

 are somewhat startled by Mr. Ridgway's statement that 

 though Linnseus^s definition of his genus Mycteria suits 

 the bird usually known as M. americana, L., the Linnsean 

 species is Ciconia maguari ! Mr. Ridgway gets over the diffi- 

 culty by changing the authorship of the specific name from 

 Linnseus to Gmelin ; and, so far as we are concerned, we 

 are content to let it be so ; but we. do not fail to notice a fine 

 opening for some one partial to such work to put quite a 

 difi'erent interpretation upon the matter,

The materials from which this Report was drawn were col- 

 lected by Mr. Ridgway himself, between June 1867 and 

 August 1869, the district investigated lying between Sacra- 

 mento City, California, and Salt-Lake City, Utah. The intro- 

 ductory portion of the Report contains careful analyses of the 

 bird-population of the several districts explored. The rest 

 of it consists of an account of each species, many of the bio- 

 graphical notes being full of interest. (See J. A. Allen, Bull. 

 Nutt. Orn. Club, 1878, p. 81.)

At p. 69 of this Report Prof. Cope gives a further account 

 of the remains of the species of bird he described in 1876 as 

 Diatryma gigantea, an Eocene bird of doubtful affinity. At 

 p. 287 more details are supplied of Vultur umbrosus, dc-
