before becoming emerald-green. Similar transitions take 

 place in tlie colouring of the plumage of C. xanthoi'hynchus. 

 The barred and rufous stage is succeeded by one in which 

 the rufous colour is replaced by coppery green, which then 

 passes into a darker and purer green, then turns into violet 

 or blue amethystine before finally assuming the amethystine 

 hue of the fully adult plumage. An example of C. xan- 

 tliorhynchus, obtained at Rangoon, passing over from the 

 rufous and coppery green stage to the violet and amethys- 

 tine adult dress, is well figured by Colonel Tickell. He, 

 however, considers that 6'. maculatus is in what he terms 

 the '' first adult " dress, and that C. ' xanthorhynchus repre- 

 sents the " second adult, or old bird " of the same species — 

 a conclusion which is contrary to the known facts. C. xan- 

 thorhynchus, a smaller bird than C. maculatus, is a ]\Ialayau 

 species M'liich ranges as far north as Hill Tipperah, and occurs 

 in the Andamans. C. maculatus is an Indian species, and 

 found not uncommonly in Pegu and Siam (C. schomburyki). 

 In fully adult plumage it has the chin and throat, but not 

 the breast, unbarred emerald-green, like the upper plumage. 



To the Tenuirostres, as understood by Colonel Tickell, are 

 devoted volume iv., with thirty-two plates. By him this 

 tribe is made to include the SittidcB, Nectarhmdce, and genera 

 such as Zosterops, lora, Phyllornis, Yufiina, Myzornis, Her- 

 pornis and Oriolus, Irena and XJpupa. 



One of the most finished drawings in the work is that of 

 Certhia discolor, taken from a Darjeeling example. That of 

 Sitta formosa is not so happy, while the chai^acters whereby 

 Sitta cinnamomeoventris is distinguished from S. castanei- 

 ventris are successfully portrayed on the plate representing 

 the two species ; and, together with that of S. himalayensis, 

 the tails are separately sketched in Indian-ink. The lovely 

 J) etidr op hila frontalis (Horsf.) is worthily depicted from two 

 Tenasserim examples. Mr. Sharpe has (Str. Feath. 1875, 

 p. 436) recently stated that the Javan bird differed specifi- 

 cally from the continental S. corallina, Hodgs. The cha- 

 racters relied on are " the under surface being more richly 

 coloured, and the throat being lilac-brown, like the breast,"
