418 BIRDS OF THE REPUBLIC OF PANAMA — PART 2 



from Portobelo had eaten 2 large caterpillars, a large ant, 2 earwigs, 

 and several berries. 



The race concinnus was named by Lawrence from specimens sent 

 to him by James McLean nan. In part 1 of the account of the 

 McLeannan collection, Lawrence (Ann. Lye. Nat. Hist. New York, 

 vol. 7, 1861, p. 290) under the family Trogonidae listed 5 species 

 by name only, without comment, one of these being "no. 21 Trogon 

 caligatus Gould." In the introductory statement Lawrence wrote 

 that the "birds comprised in this catalogue were collected by James 

 McLeannan, Esq., on the Atlantic side of the Isthmus of Panama 

 along the line of the Panama Railroad from near the coast to about 

 a central point between the two oceans." In the description of 

 concinnus as new in part 3 of his account of this material Lawrence 

 (idem, vol. 7, 1862, p. 463) does not give the locality for his type 

 but says of it "I am not able to make this agree with any of the 

 described species of the genus. It comes nearest to T. caligatus." It 

 may be assumed that the type is the bird listed under the latter name 

 in part 1, and that the type locality is as designated above. North 

 of South America the species viola ceus ranges through Central Amer- 

 ica into Mexico. Separation of two races in this area is based on 

 differences in size, the northern birds being larger. While Costa 

 Rican birds have been included in the range of the southern race 

 concinnus Zimmer (Amer. Mus. Nov., no. 1380, 1948, p. 36) noted 

 that the population of that country is nearer the northern form 

 braccatus. The considerable series of the species in the National 

 Museum supports that conclusion, as shown by the following series 

 of measurements : 



Males of Trogon violaceus braccatus (15 from Mexico, Guatemala, 

 Honduras, and Nicaragua) , wing 119.0-125.5 (122.4), tail 120.0-130.0 

 (125.7), oilmen from base 16.2-18.7 (16.9), tarsus 13.2-14.8 

 (13.9) mm. 



In our series from Costa Rica 10 males measure as follows: wing 

 114.0-122.2 (120.4), tail 116.0-124.0 (120.4), culmen from base 16.5- 

 18.4 (17.0), tarsus 13.2-14.6 (14.0) mm. These dimensions show 

 that while wing and tail average slightly less than braccatus they are 

 nearer the northern group than to concinnus found in Panama. 



On the basis of a male collected by von Wedel at Perme, eastern 

 San Bias, on March 27, 1930, Griscom (Bull. Mus. Comp. Zool., 

 vol. 72, 1932, p. 338) has recorded Trogon violaceus caligatus, a 

 subspecies that ranges through the tropical lowlands of northern 

 Colombia and northwestern Venezuela, as an additional race from
