Mexican hot-lands, and has, as is well-kno-nn, eccentric 

 breeding-habitSj but not those of our European Cuckoo. 

 Several females lay their eggs in one nest, in which they sit 

 in company, while, there not being room for all of them at 

 once, the excluded ones perch upon the margin of the nest 

 and wait their turn to " go on/' 



On the ride from Tehuantepec to Oaxaca an abundance 

 of bird-life was met with. '^ Long-tailed Parrakcets whirled 

 round in swarms, and the short-tailed Lories climbed 

 about in pairs, while little Inca Doves and brown Pigeons, 

 Crackles and Cassiques, Hawks and Cormorants, Herons, 

 and black and red-faced Vultures were also to be seen." 

 But the pretty long-tailed blue and white Jays — well-named 

 Calocitta formosa — were the favourites, and watched the 

 party from the overlianging branches with their top-knots 

 well curved forwards (as shown in an accompanying illus- 

 tration), and were so confiding as to whistle back when 

 whistled to. It is new to us that the Mexican Hang-nests 

 (^Icterus) have taken to tying their pendent houses to the 

 telegraph-wires (p. 207), and that Hirundo callorhina (what- 

 ever that may be ?) places its nests on the eaves of the old 

 houses. But the reader of Dr. Gadow's volume will find 

 these and other interesting facts described in its pages, 

 and we strongly recommend its perusal, although we think 

 that a little more ornithology might have been well intro- 

 duced into it.

In January (see above, p. 175) we noticed the issue of 

 Part III. of this important work. We have now to record 

 the publication of the fourth part, which continues the 

 account of the numerous species of (Estrelata until its
