2 28 Birds of San Pedro Mar fir. [zoE 



white simple eyes, each with a minute pupil-like black 

 dot; four arranged in nearly a semi-circle, with the exterior 

 or convex side dorsad; the other two situated ventrad of 

 the front one in the semi-circle, one anterior to the other. 

 Labrum rather deeply notched anteriorly, light fulvous; adjoin- 

 ing border of clypeus narrowly concolorous. Antennae sunken 

 in a small excavation anterior to eyes, apparently two-jointed, 

 joints about equal in length, second hardly narrower and 

 terminated with a style-like hair. Mandibles rather stout, sub- 

 quadrate in outline, flattened, faintly four-notched, therefore 

 faintly serrate with four or five teeth. Maxillae and labium 

 whitish; maxillary palpi apparently two-jointed, basal joint 

 stouter, terminal joint more elongate and slender. Three pairs 

 of four-jointed true legs on the thoracic segments, terminated by 

 a brownish chitinous claw. Five pairs of prolegs, on joints 7 

 to 10, and 13, the anal pair stouter, fleshier, and somewhat 

 longer. 



Described from two alcoholic specimens, perhaps not fully 

 grown, taken from cases May 13 and 15. Color of head and 

 body noted in life. The length of the segments is drawn from 

 the better preserved specimen. The proportions are slightly 

 diff"erent in the other. 



BIRDS OF SAN PEDRO MARTIR, LOWER CALIFORNIA. 



BY A. W. ANTHONY. 



Mr. W. E- Bryant's excellent Catalogue of the Birds of 

 Eower California has left but little to record from the northern 

 part of that peninsula, but the notes furnished by the present 

 writer were necessarily very fragmentary owing to the collections 

 as well as many notes being inaccessible at the time. It is to 

 correct this deficiency and at the same time record the obser- 

 vations of a trip through that region the past season that the 

 present paper is offered. The expedition crossed the national 

 boundary at Tia Juana, fifteen miles from San Diego, on April 

 17, 1893, and proceeded by easy stages to the western base of 

 San Pedro Martir by way of Ensenada and Colnett. The first 

 benches of the mountain were not reached until May 5.
