i c 9^J Cherrie on Costa Rican Birds. 3^S 



52. Piranga rubra. — Not an uncommon bird tor a little time after they 

 first arrive in the fall. My first note is for Oct. 26, 1SS9, when I saw 

 several. I saw none in the spring, but there is a female in the museum 

 collection labelled "San Jose, Jan 10, 1S85. A. Alfaro." 



53. Chelidon erythrogaster. — First noted Sept. 8, 1889, when they 

 were quite abundant. They were common until early in February. 



54. Stelgidopteryx serripennis. — Very common throughout the rainy 

 season, but seldom seen in the dry season, from early in December until 

 the latter part of April. 



55. Vireo olivaceus. — But seldom seen. I took a female Oct. 9, 1889. 

 Noted the last this spring April 20. 



56. Vireo flavoviridis. — Breeds abundantlv. disappearing from San 

 Jose only during the dry season. In the fall of 1S89 the last were seen 

 Sept. 29, several having been killed the night before. They return about 

 the middle of April. For fuller notes on V. flavoviridis see the present 

 number of 'The Auk' pp. 329-331. 



57. Vireo philadelphicus. — I have only once noted the Philadelphia 

 Vireo. April 23, 18S9, I took a female. 



58. Vireo flavifrons — Seldom met with here. The first arrival in 

 1SS9 was a female Oct. 25. Feb. 9, 1S90, I saw two; they were the last. 



59. Mniotilta varia. — Arriving in San Jose the middle of February, 

 18S9, I made no notes on the Black-and-white Creeper that spring, and 

 the first noted in the fall was Aug. 20, when I saw one industriously 

 searching the branches for food. The next were noted Aug. 23, when 

 two females were taken, both birds of the year. They are never at 

 any time even tolerably common, and from Sept. 15, they are exceed- 

 ingly rare. One was noted Nov. 10, and the last seen, a fine male, was on 

 Feb. 2S, 1S90. 



60. Protonotaria citrea. — The first were noted Oct. 13, 1S89, on which 

 date they were not uncommon. They were seen again Oct. 21. A skin 

 in the museum collection is labelled "San Jose, Oct. 29, 1S87." None 

 were seen in the spring. 



61. Helmitherus vermivorus. — I find a single skin in the Museo 

 Nacional, labelled "San Jose\" 



62. Helminthophila chrysoptera. — Took a fine female Sept. 15, 1889. 

 They were quite abundant on that date. This is the only note I have 

 made regarding this species. 



63. Helminthophila peregrina. — I have no notes for the spring of 18S9. 

 In the fall the first were noted Sept. 17; several were seen. None were 

 met again until Oct. 14, when I took a female. From that time on they 

 were common until Oct. 27, when they were very abundant, the most so 

 of all the Warblers. Then they seemed to decrease in numbers until 

 D3T;. 5, when I again found them abundant. Through January and Febru- 

 ary they were tolerably common. The last were seen March 6. 



64. Dendroica aestiva. — This is one of the most common of the War- 

 blers. The last was seen in the spring of 1S89 on May 9. The present 

 year I saw the last May 11. They made their first appearance in the
