Elaborate treatment of 6 spp. of the genus, with copious synonymy, extended descriptions, 

 and critical comment; much also on the literature of the subject. The species recognized aa 

 valid are 7 in number, viz : M. inelanoleucus, mirandollii, guerilla, zonothorax, rufieollis, pel- 

 zelni, sp. u., p. 494, concentricus. Details of heads, feet, and wings are figured. The appendix, 

 pp. 500-502, gives biographical notes on M. inelanoleucus, by A. J. Grayson. — The author 

 afterward reviewed his work in Ibis, 1876, pp. 1-5, q. v. See also his original paper on the
