 49221. Adult (sex not indicated, but apparently female) . "Central Guate- 

 mala (Coban to Clusec)." Entered into the museum register on Oct. 

 24, 1867. Collected by Henry Hague. 

 50411. Adult (sex not indicated, but apparently male). Guatemala, De- 

 partment of Guatemala, Guatemala. Entered into the museum register 

 on Mar. 4, 1868. Collected by C. H. Van Patten. 

 Ridgway had "a considerable series ... of Guatemalan Bluebirds," and 

 referred to specimens in the United States National Museum from "Coban to 

 Clusec," Tactic, and Coban. No mention was made of the bird from the 

 City of Guatemala, but since Ridgway himself at some time made No. 50411 

 the lectotype, it presumably formed part of his original material. The four 

 listed above seem to be the only potential cotypes still in the collection. 



Griscom {op. cit., p. 314) has shown that S. s. guatemalae must be syn- 

 onymized with whatever name is used for the breeding form of southeastern 

 Mexico. Support for this view is offered by the fact that No. 30661, a 

 cotype of guatemalae, is also a paratype of Baird's azurea.
