line, each comb with about ten teeth. Penultimate ventral segment with a 

 median process and ciliate border; terminal segment of female with fine 

 •ciliate border. 



Described fro.m a number of specimens collected from the 

 burrowing owl, Speotyto cunicularia hypogjea, by Prof. Lawrence 

 Bruner, Lincoln, Nebraska. 



The peculiar combs of fine hair-like teeth on the third segment 

 of the abdomen, while not confined to this species are, with 

 other characters, quite distinctive and are of special interest as 

 showing the range of morphological features presented by mem- 

 bers of this group. Since noting them in this species I find 

 Piaget had described similar combs on the femora of his pectini- 

 feruni, a species occurring on IVIih-ogos pezoporos. Of these he 

 says " four to 5 petits peignes dont les dents diminuent insensi- 

 blement de longuer." He makes no mention of combs on the 

 abdominal segment, which in my species have a very similar 

 structure. About the only function that can be assigned to them 

 is that of assisting in holding the body in definite positions in its 

 attachment to the feathers. 



ColpocepJmhuii spiniilosian Piag. var. minor Kellogg. ( New 

 Mallophaga III. p. 112. ) 



A female specimen from the American dunlin, Tringa alpina 

 pacifica, from Prof. Bruner, "Salt Lake Haggard," corresponds 

 so closely with the form described by Kellogg from Calidris 

 arenaria, Pacific Grove, Cal., that I do not hesitate to so place it.

Kellogg described this species from one male taken from Ardea 

 egretta. I have one mature female and three immature individu- 

 als taken at Ft. Collins, Col., by A. C. Stephenson, from the 

 American bittern, Botaurus lentiginosus, which agree in almost 

 every detail and description as separate species would seem 

 unwarranted. In shape, markings and distribution of hairs and 

 bristles there is scarcely any dift'erence, but the meta-thorax is 

 narrower and the lateral margins more strongly colored than 

 shown in Kellogg's figure. Length of male is given as 1.72, and 

 this female is nearly 1.80 mm.
