480 General Notes. [^ t k 



(Phloeotomus pileatus abieticola) in this State is May 10-15, consequently 

 I was surprised to find a nest on May 20, 1918, in northern Huntingdon 

 County containing three nestlings about one week old. The nest was 

 seventy feet up in the dead top of a large rock oak in a thick forest. 



Judging by the age of the young birds and allowing eighteen days for the 

 incubation of the eggs, this early pair must have had a fresh set about 

 April 25. 



Three other nests found by Richard C. Harlow and the writer this year, 

 in the same county held fresh and slightly incubated eggs on May 16 and 17, 

 respectively. — Richard F. Miller, Philadelphia, Pa. 



Relative Length of the Intestinal Caeca in Trogons. — In his article 

 on ' The Anatomy of the Cuban Trogon ' in ' The Auk ' for July, 1918 

 (p. 286), Dr. H. L. Clark records the length of the intestines and cseca of 

 this trogon and remarks " The cseca are thus relatively very long, much 

 longer than in the species of Trogon and Pharomacrus examined by 

 Garrod." 



I have examined the viscera of twelve specimens, representing six species, 

 of Central American Trogons. These with the four individuals recorded 

 by Garrod and Clark give us for comparison a total of eight species be- 

 longing to three very distinct groups of Neotropical Trogonidae. The 

 following figures express the ratio of the length of the caeca to that of the 

 intestines, the latter being represented by 100. 



Pharomachrus mocinno (7 specimens), 9.3 



Trogonurus mexicanus (1 specimen), 10.6 



puella (2 specimens), 13.8 



curucui (1 specimen), 14.6 



Chrysotrogon caligatus (1 specimen), 16.2 



Trogonurus elegans (2 specimens), 16.7 



Trogon melanocephalus (1 specimen), 17.2 



Priotelus temnurus (1 specimen), 17.8 



Thus in Pharomachrus the cseca average slightly more than one-eleventh 

 of the total length of the intestinal tract, while in Priotelus they exceed 

 one-sixth of the intestinal length. In Pharomachrus they are relatively 

 shorter than in the other genera but Trogonurus mexicanus connects the 

 two groups. The figures indicate that the cseca of Priotelus are a trifle 

 longer than those of Trogonurus, Chrysotrogon and Trogon, but there is 

 great individual variation in the length of these appendages and additional 

 specimens will undoubtedly show that there is at most only a slight average 

 difference. — W. DeW. Miller, American Museum of Natural History,
