The ebook has been re-arranged so that the separate parts have a smoother flow. The top parts of the pages have been left intact, but the bottom parts have been collected together and moved, so that the Lecture text for each ORDER precedes the tabular listing and descriptions for that ORDER. The only exception is for ORDER XXI. ORDER XXI.--Perching-Birds--contains 11,500 species, more than three-fifths of the world's 19,000 birds. It has been arranged into sets of suitable groups of FAMILIES, to make it easier to access. ==== has been used to separate the Lecture from the Tabular matter. From "PREFACE TO THE SECOND EDITION.": "In response to requests from beginners, a table has been added on page 190. This table shows the page on which a bird of a certain size may be found." As the page numbers are an integral part of the field guide, and necessary for the identification of birds seen in the field, in flight, or found dead, they have been inserted into the tabular section, as [Page xx]. Sometimes a page has contained the end entries of one ORDER, or one Family, and the beginning entries of the next. In these few instances (e.g. [Page 18a] and [Page 18b]; [Page 188a] and [Page 188b]), it may be necessary for the reader to search both sections of the page. For birds mentioned in the Lecture, it would be necessary to search by bird name. NAMES RECENTLY AMENDED (located after the INTRODUCTION). It seems important to have these new names available, so they have been added to (e.g.) =20 Slate-breasted Rail= .... as [~20 _Rallus pectoralis._] so: =20 Slate-breasted Rail= (Short-toed), Lewin Water-Rail, _Eulabeornis (Hypotaenidia) brachypus_, A., T., Auckland Is. =vt. Eur. Water-Rail. [~20 _Rallus pectoralis._] See also the explanatory notes in the PREFACE, and in the PREFACE TO THE SECOND EDITION. "The number at the right side of the page is the length of the bird in inches (from the tip of bill to the tip of tail)." ... so: 1 1 =2* Mallee-Fowl=, Lowan, Native Pheasant, Pheasant (e), _Leipoa ocellata_, N.S.W., V., S.A., W.A. Stat. r. _mallee scrubs_ 24 Like a small turkey; neck light fawn-gray; back, wings spotted white, black, brown; f., smaller. Seeds, ants. This means there is one genus of Mallee-Fowl in the world, and it is found only in Australia. It is listed in this book as Bird number 2, which has a colored illustration, indicated by the asterisk, *. It is stationary (not migratory), rarely seen, lives in mallee scrubs, and is 24" long. It resembles a small turkey; its neck is light fawn-gray; its back and wings are spotted white, black, and brown; the female is smaller; and it feeds on seeds and ants. Note (From NOTE following "PREFACE TO THE SECOND EDITION."): A.--Australian Region (from Wallace's Line to Sandwich Islands and New Zealand, see map p. 10). 'Sandwich Islands' is an old name for Fiji. * * * * *
