On some Svrcres of Parastres hitherto undescribed. By 
AxexanDER Macauister, Professor of Zoology and 
Director of the Museum, University of Dublin. 
In the course of the dissection of some birds and mammals 
in the anatomy department of Trinity College, Dublin, I met 
with the following species of parasites, which I think are as 
yet undescribed. The animals from which these specimens 
were obtained were mostly purchased by the Rev. Dr. 
Haughton, from the Dublin Zoological Gardens, and I have 
looked in vain for the description of these species in the works 
of Denny, Walckenaer, Nitzsch, Burmeister, Giebel, or 
Rudow; so I suppose them to be as yet unnamed. The new 
species are as follows: 
1. Lipeurus Phenicopteri. 
This was obtained from the body of a fine female flamingo 
Lipeurus Phzenicopteri. 
Labrum.
