LI.—A Collection of Entozoa, chiefly from Birds, from the 
Murman Coast. By H. A. Bays, M.A. 
(Published by permission of the Trustees of the British Museum.) 
THE material to be described in this paper was collected by 
Surg.-Lieut. E. A. Cockayne, R.N., while in H.M.S. ‘ In- 
trepid’ (then serving off the Murman coast), and kindly 
presented by him to the British Museum. The collection 
consists chiefly of parasites of birds shot by Dr. Cockayne 
and his fellow-officers at localities on the Murman coast, 
Kola Peninsula, Arctic Russia. 
18 species of Cestodes are represented (excluding larval 
forms), 3 of Nematodes, and 1 of Acanthocephala. Of the 
Cestodes, 5 appear to be new species or varieties, while of 
several the specific determination remains doubtful.
