this bird "its further extension southward reaches to the line of the 

 Panama railway," which indicates that the bird was secured somewhere 

 near Lion Hill Station. The record by Arce from Santiago also is 

 significant in being an interesting lowland record where the bird is no 

 longer found. Arce's labeling, however, is not always reliable. North 

 of Panama, this race occurs on the Caribbean slope to eastern Honduras. 



Although Hellmayr (Cat. Birds Amer., pt. 11, 1938, p. 48) con- 

 sidered this race to be of doubtful validity, and an occasional C. c. 

 polio gaster may have the scapulars yellowish instead of grayish, the 

 smaller size of scapularis (Ridgway, Birds North and Mid. Amer., pt. 

 1, 1901, pp. 655-656) is quite consistent, and most specimens can be 

 separated by color in any case. 



In Costa Rica, Skutch (Publ. Nutt. Orn. Club, no. 10, 1972, pp. 211- 

 218) found a pair building a nest in early April. Concealed amid epi- 

 phytes on a small tree 3 m from the ground, the nest was a shallow bowl 

 made of rhizomes of an epiphytic fern with inner layers of dicotyle- 

 donous leaves and long, coiled strands of Tillandsia. The interior mea- 

 sured 7.5 cm in diameter by 2.75 cm deep. Eggs were laid on April 20, 

 22, and 23. They were dull white, mottled and spotted, especially on the 

 thicker end, with bright shades of brown; their measurements averaged 

 17.0x26.3 mm. Apparently only the female incubates the eggs, which 

 take 13 days to hatch. Both parents feed the young, and at the nest 

 Skutch watched they were assisted by a helper of unknown sex. At 

 11 or 12 days, when well feathered except on their still naked heads, 

 the young grosbeaks left the nest, flying as far as 13 m on their first 

 flight, and disappearing with their 3 attendants into the forest.

Caryothraustes canadensis simulans Nelson, 1912, Smiths. Misc. Coll., 60(3), p. 

 16. (Cana, 3,000 ft., Darien, Panama.) 



Characters. — Slightly smaller than scapularis; underparts entirely 

 yellow; rump same color as back, not gray. 



Measurements. — Male (1 from Darien, the type), wing 84.9, tail 

 68.1, culmen from base 17.7, tarsus 19.8 mm. 



Female ( 1 from Darien) , wing 85.0, tail 66.1, culmen from base 17.4, 

 tarsus 18.2 mm. 



Resident. Known only from a male and female collected at Cana 

 (900 m), Darien, by E. A. Goldman on June 10 and 11, 1912. The 

 stomach of the male contained finely ground remains of three or more 

 species of beetles including one curculionid 65%, vegetable pulp inde-
