FAMILY TR0C.0N1DAF. 403 



at Remedios, Antioquia, in northwestern Colombia, is dull white with 

 a faint gloss, short oval in form, with measurements of 28.7x24.2 

 mm. According to the collector ( Sclater and Salvin, Proc. Zool. Soc. 

 London, 1879, p. 535) this bird nests "in the holes of palm trees, and 

 lays two white eggs." 



In comparison of my series taken in Panama with a similar group of 

 skins recently collected for us by Carriker in northwestern Colombia 

 I note that females in the Colombian group average slightly grayer 

 on the dorsal surface so that it may prove that the more southern birds 

 should be recognized as distinct. I note also that male, female, and 

 immature male, taken February 1, 1964, at Pucro, Darien, probably a 

 family as they were near together, have decidedly heavier bills than 

 any others seen. 



Linnaeus (Syst. Nat., ed. 12, vol. 1, 1766, p. 167) listed this species 

 from Brisson's descriptions under two names, Trogon strigilatus, 

 which is the female, and Trogon viridis, the male. Both names have 

 been used, with strigilatus accepted in most recent accounts. Zimmer 

 (Amer. Mus. Nov. no. 1380, 1948, p. 26) however, has pointed out 

 that Burmeister (Syst. Uebers. Thiere Brasiliens, vol. 2, 1856, p. 277) 

 who cited both names, from Linnaeus, as first reviser selected viridis, 

 the term covering the male, for the species, with strigilatus, from 

 the female, as a synonym. From this under the Rules of Nomenclature 

 viridis is the valid name for the species. 



With regard to the name chionurus, current for this race, it is 

 indicated in the heading above that this dates from April 1871. Trogon 

 eximius Lawrence, also for this race, questionably dated February, 

 March 1871, possibly may be older. The Annals of the Lyceum of 

 Natural History of the period in question were issued by the society 

 in installments. Lawrence's paper entitled "Descriptions of New 

 Species of Birds from Mexico, Central America, and South America, 

 with a note on Rattus longirostris," was read before the Society on 

 January 30, 1871, and was printed in volume 10, pages 1 to 21. At the 

 bottom of page 1 is the date February 1871. It was followed in the 

 journal by a paper by Bland and Binney, which begins at the top of 

 page 22, on the reverse of the last sheet of Lawrence's contribution. 

 Lawrence had separates printed also, from the same type, without 

 the heading "Annals of the Lyceum of Natural History," and with the 

 back of page 21 blank, but otherwise identical with the volume, as 

 is shown by copies in our library. It may prove, from evidence not 

 at present available, that these were distributed in February or
