494 Recently published Ornithological Works. 



As regards the prospects of the ' Catalogue of Birds of the 

 British Museum ' generally^ the subjoined table will show 

 what has noAv been accomplished of this great work. It 

 seems that in seven years five volumes have been issued, con- 

 taining an account of 1817 species, or, on an average, (say) 

 360 species to a volume. The total number of known birds 

 being estimated at 10,800, or thereabouts, it is easy to calcu- 

 late that, 360 to each volume, it will take thirty volumes to 

 complete the work. It is therefore much to be hoped that it 

 will be found practicable to issue the volumes a little faster ; 

 or we fear that many of us will hardly live to see the com- 

 pletion of the Catalogue.

93. Tegetmeier and Blyth on the Cranes. 



[The Natural History of the Cranes. A Monograph by the late Edward 

 Blyth, C.M.Z.S. Greatly enlarged, and reprinted, with numerous illus- 

 trations, by W. B. Tegetmeier, F.Z.S. Published for the author by

Mr. Tegetmeier has done a good work in reprinting Blyth's 

 papers on the Cranes, which appeared in the ^ Field'' in 1873, 

 and, by additions from other sources and illustrations, has 

 made a useful and interesting volume of 90 pages, which 

 contains a summary of nearly all that is known respecting 

 this interesting group. Mr. Tegetmeier recognizes 16 species 

 of Cranes — 2 belonging to the genus Balearica, and 14 to 

 Grus, besides 2 doubtful members of the last-named genus. 

 He has taken great pains Avith the references, and has shown 

 that (as already noted, P. Z. S. 1880, p. 93) the specific term 

 " reguloi'um" commonly applied to the southern form of
