Sept., 19o6 I BIRDS COLLECTED BETWEEN MONTEREY AND SAN SIMEON I23 mammals. Two hundred and fifty-two specimens of birds, a few large mammals, besides 312 specimens of small mammals, some reptiles and a good many scraps of plants were collected, the latter only for identification as no time could be allowed for the preparation of herbarium specimens. I am indebted to Professor W. R. Dudley for identification of most of the plants and aid in the preparation of the accompanying map. South of Monterey the main ridge of the coast range, or, as it is here called, the Santa Lucia range, lies very near the coast. The descent therefore from heights of 30oo to 5oo0 feet to sea-level within 5 or 6 miles is very great and the deep canyons cutting this western slope add to its extreme rough character. North of the Big Sur where the country is less mountainous and south of Mt. Mars where the range takes a sudden turn inland leaving a wide level country about San Sinleon, there is considerable farming done and good roads are to be found; but between the Big Sur and San Carpojo on the western side of the range there are no roads and very little farming is done besides cattle raising. The region traversed was par- ticularly interesting in that it was found to be the southern limit of the Humid Coast Belt of California. Several northern plants and animals find their southern limits in this place and some northern forms inter-grade thru this region with closely allied southern forms. That part of Monterey county between Salinas Valley and the coast, can be roughly divided in ............ to two very different faunal areas, namely the interior pine regions and the coast region proper. It PART Or MONTS[RS[Y COUNTY, CALIFORNIA. TO SHOW LOCALITIES was in this coast region that we REr?RR?O TO BY I-I. O. J?NKIN$ spent most of our time, visiting the pine regions only on the headwaters of Big CreekSfor a week and on the ridge above Partington canyon and the ridge above Spruce Creek for a day each. The coast region is much like other parts of the Cali- fornia coast belt but is much narrower than the northern coast belt and the humid conditions are much more restricted. The redwood (Sequoia sempervirens), a typical form of the humid coast for- est, was found on nearly all of the creeks on the west side of the first ridge of the coast range south of Carmel Bay, as far as a small canyon just north of Sal- mon Creek! arid was greatly restricted by local conditions:
