Australian Region Australian Papuan Antillean (B) Neogaea or II.
The Antillean Subregion is in many respects one of the most suggestive and interesting.
For narrow as are the channels between Cuba and the opposite coast of Central America, between the Bahamas and Florida, and between Grenada and Tobago, the fauna of the Antillean chain, instead of being a mixture of that of the almost contiguous countries, differs, much from all, and exhibits in some groups a degree of speciality which may be not unfitly compared with that of oceanic islands..
There is no family of birds common to the Nearctic area and the Antillean subregion without occurring also in other parts of the Neotropical region, a fact which proves its, affinity to the latter.
An Antillean rabbit is very abundant.
The Caribbean chain along the north coast is part of the Antillean system, and here the strike of the folds is nearly west to east or west-south-west to eastnorth-east.
The " exceedingly irregularly rounded, low-pointed mountains and hills covered by dense forests " (Hill) are Antillean, not Andean, and lie at right angles to the axes of the systems of North and South America.
