282 THE ZOOLOGIST. 
Since the date of Blyth’s publication another species has been 
added to the list, namely, the Black-necked Crane, Grus nigri- 
collis, which was discovered by the Russian explorer, Colonel 
Prejevalski, at Koko-nor, in Mongolia (thonght to be the northern 
limit of its distribution), and was described and figured in the 
second volume of his ‘Birds of Mongolia,’ which appeared in 
1876. The coloured plate there given of this species has been 
faithfully reproduced in the monograph now before us, together 
with a translation of the discoverer’s account of it. 
Amongst the additions and corrections made by Mr. Teget- 
meier to Blyth’s original memoir, we notice some rectifications of 
synonymy. It appears that the proper scientific appellation of 
the Kaffir Crowned Crane is Balearica chrysopelargus of Lichten- 
stein, not regulorwm as erroneously attributed to him by Bennett. 
Blyth described the White-naped Crane of Northern Asia under 
the name Grus antigone, Pallas, overlooking the fact that the 
name antigone was appropriated by Linneus to the Greater 
Indian Crane of Edwards long before Pallas gave the same name 
to the White-naped Crane. This Mr. Tegetmeier has set right 
in the present volume, wherein he also points out that the Grus 
torquata of Blyth, following Vieillot, should be known as Grus 
collaris of Boddaert, this name having priority by more than half 
a century. 
The utility of this monograph is enhanced by the plates with 
which it is illustrated, amongst which we particularly notice a 
full-page illustration of Grus leucauchen, in which the artist, Mr. 
T. W. Wood, has happily hit off the graceful attitude so charac- 
teristic of this group of birds, and two plates which contain 
figures of the heads of eight other species. Nor should we omit 
to notice the coloured frontispiece, from a sketch by Professor 
Flower, representing the curious appearance presented by a vast 
flock of Demoiselle Cranes, as observed by him in Egypt during 
the period of migration. 
The thanks of ornithologists are due to Mr. Tegetmeier for 
having placed within their reach such an excellent edition of a 
valuable monograph.
