Near the head of the hollow rises a stream of clear, cool water, at present 

 everywhere confined within its banks but formerly expanding, at a point 

 just above where it escapes by a narrow canon through the encirclincr 

 hills, into a shallow lagoon from which the mountain derived its name. 

 After descending through the ravine to lower levels and mino-lino- its 

 waters with those of other mountain brooks, this stream is said to sink 

 into the ground, reappearing again a few miles above the town of Sau 

 Jose, below which it empties into the sea. 



In this attractive little subalpine valley ]\[r. Frazar spent, as I have 

 already stated, upwards of six weeks, collecting assiduously and obtain- 

 ing full series of most of the birds which had been previously reported 

 from these mountains as well as several novelties which I have since 

 described. Unfortunately he was too early for nests and eggs. Indeed 

 only a very few of the birds had begun laying up to the date of his 

 departure (June 9). He was assured by the deer hunters and cattle 

 herders whom he met that the height of the breeding season is not 

 reached here before July. He attempted to return at this time, but 

 was prevented from doing so by a serious illness. 



On November 27, however, he paid a second visit to the valley, 

 remaining there up to December 4. The weather, during this period, 

 was cold and damp and the mountain shrouded in mist. There were 

 but few birds, and of these the greater number belonged to feeble- 

 winged or habitually sedentary forms, such as Titmice, Nuthatches, 

 Jays, etc., most of the summer species having evidently descended to the 

 lowlands or migrated to warmer latitudes, to pass the winter. Nor had 

 their places been taken by winter visitors from further north, for the 

 Ferruginous Rough-legged Hawk was literally the only addition made, 

 on this occasion, to the list of birds observed the previous spring. 



As the latter will be fully treated in their appropriate places in my 

 paper, it seems unnecessary to mention here any but the more charac- 

 teristic or interesting species, such as the St. Lucas Robin, Grinda's 

 Bush-Tit, Ashy Titmouse, St. Lucas Nuthatch, Western Martin, St. 

 Lucas Swallow, Mountain Towhee, Baird's Junco, St. Lucas Flycatcher, 

 Large-billed Wood Pewee, Xantus's Hummingbird, Narrow-fronted 

 Woodpecker, Hoskins's Pygmy Owl, Dwarf Horned Owl, and Viosca's 

 Pigeon, most of which were abundant and in the perfection of their 

 nuptial plumage. 



San Jose. — At the close of his third visit to Triunfo Mr. Frazar 

 proceeded to San Jose del Cabo by a road which crosses the mountains 

 to San Antonio and next passes through San Bartolo, beyond which it
