Messrs. Sclater and Salvin, and Professor Newton, divide the Neotropical Region into six sub-regions, of which our "Brazilian sub-region" comprises three—the "Brazilian," the "Amazonian," and the "Columbian;" but, after due consideration, it does not seem advisable to adopt this subdivision in a general work which treats of all the classes of terrestrial animals. (See p. [27].)
Mr. Salvin, who has critically examined the ornithological fauna of these islands, has kindly corrected my MS. List of the Birds, his valuable paper in the Transactions of the Zoological Society not having been published in time for me to make use of it.
This name will be used for the whole island of St. Domingo, as being both shorter and more euphonious, and avoiding all confusion with Dominica, one of the Lesser Antilles. It is also better known than "Hispaniola," which is perhaps the most correct name.
Myospalax has hitherto formed part of the next family, Spalacidæ; but a recent examination of its anatomy by M. Milne-Edwards shows that it belongs to the Muridæ, and comes near Arvicola.
The species of the genera Phylloscopus and Hypolais are so mixed up in the Hand List, that Mr. Tristram has furnished me with the following enumeration of the species which in his view properly belong to them, by the numbers in that work:—
| Phylloscopus. | Hypolais. |
| 3032 | 3026 |
| 3033 | 3028 |
| 3048 = 3038 | 3029 |
| 3039 | 3054 = 3031 = 3036 |
| 3063 = 3047 = 3054 = 3061 | 3042 |
| 3048 | 3043 |
| 3049 | 304 |
| 3050 | 3062 = 3047 |
| 3051 | 3046 = 2932 |
| 3052 | 3035 |
| 3053 | 2976 |
| 3056 = 3081 | |
