"FAUNAL AREAS II 
Birds which find their southern breeding limit in the Transition 
zone, fall roughly into two classes, (1) upper Transition species 
which are limited in their breeding range on the north by the 
Canadian fauna and extend southward so as slightly to overlap 
the Carolinian zone; (2) lower Canadian species which breed 
more or less frequently in the upper ‘Transition zone. 
The following twelve species are examples of the first class :— 
Rallus virgintanus, Porzana carolina, Podilymbus podiceps ?, Anas 
obscura ?, Empidonanx minimus, Empidonax traillit alnorum, Tachyctneta 
bicolor ?, Hylocichla fuscescens, Dendreca pennsilvanica, Dolichonyx oryzt- 
vorus, Melospiza georgiana, Passerculus sandwichensis savanna. 
The second group includes the following eleven birds which 
breed in Massachusetts : — 
Gavia imber, Larus argentatus ?, (Weepecket Id., Auk, IX, 1882, p. 
226), Nuttallornts borealis, Vireo solttartus, Parus atricapillus, Hyloct- 
chla guttata pallasit, Dendraca virens, Compsothlypis americana usnee ?, 
Helminthophila rubricapilla, Loxta curvtrostra minor ?, Carpodacus pur- 
pureus ?. 
Cape Cod because of its peculiar character, deserves a passing 
mention. The Gulf Stream is near enough on the south to make 
its influence felt, and the cold Polar current flows not far away on 
the north. Its sandy soil supports a growth of oaks and pitch 
pine woods in many places, and cranberry bogs alternate with dry 
fields. The long Usvzea moss grows over a large part of the Cape 
in the woods, affording thus a home for the Northern Parula 
Warbler. Hermit Thrushes and Olive-sided Flycatchers summer 
in small numbers in certain places. On the other hand so south- 
ern a species as the Mockingbird has been found to probably 
breed at Hyannis and North Truro, and the Florida Gallinule at 
Provincetown. Bobolinks, Indigo Birds, and Rose-breasted Gros- 
beaks are said to be entirely absent from the Cape in summer. 
Among other interesting species of this area, the Terrapin (JZa/a- 
clemys terrapin)’ a southern reptile, occurs in the waters along 
1The Terrapin was first recorded from Massachusetts by Dr. J. A. Allen 
(Proc, Bost. Soc. Nat. Hist., XIII, 1871, p. 260, read Mar. 16, 1870.) Speci- 
mens were noted from New Bedford, Wareham and Nantucket. It was again 
’ recorded by Mr. O. Bangs (7é/d., Vol. 27, pp. 159-161, Oct., 1896) who ob- 
tained specimens from the same region.
