TYPE SPECIMENS OF BIRDS 179 



20499. Adult male. Duenas (near Ciudad Guatemala Antigua), Depart- 

 ment of Sacatepequez, Guatemala. February 3, 1858. Collected by 

 Osbert Salvin. Original number 64. 

 At the original description, no mention is made of the number and owner- 

 ship of the types. Salvin states (Catalogue of the birds in the British 

 Museum 16:48, 1892), however, that the types are three adults, taken by 

 himself in February at Duenas, which were earlier in the Gould Collection. 

 Since the name osberti appeared as a nomen nudum as early as January 

 (see Ibis, p. 40, 1860), and was first associated with a description at the 

 meeting of the Zoological Society on June 12, while our specimen was not 

 received from Salvin until December 1860, and since, moreover, its data 

 are quite like those of the London cotypes, there is every reason to suppose 

 that No. 20499 was one of the original series turned over to Gould for study, 

 part of which was then retained by the describer, while the remainder were 

 returned to the collector.

 =Cynanthus latirostris lawrencei (von Berlepsch). See Ridgway, Birds

 I list this specimen as a type with some misgivings. Ridgway's name, 

 derived from von Berlepsch 's MS., came out in September 1887, but von 

 Berlepsch's own homonym had already appeared in July (between the time 

 Ridgway wrote his description and the date of its publication). 



Despite the fact that von Berlepsch referred to our specimen at his original 

 description, he had never set eyes upon it ; he had sent one of his own birds
