2 "TERRA NOVA" EXPEDITION. 



the remarkable richness of the Antarctic pycnogonidan fauna ; and, at the same time, 

 the fact that one species in every four in this collection has to be described as new 

 helps to remind us how incomplete our knowledge of this fauna still is. 



I wish to acknowledge the assistance that I have received from Mr. T. V. 

 Hodoson, who has very kindly made available to me much of the unpublished 

 results of his study of the " Gauss " collection, and has allowed me to borrow for 

 examination the types of many of his new species. I am also under particular 

 obligations to Prof E. L. Bouvier, of Paris, for the generous way in which he has 

 invariably responded to my requests for information and for specimens. I shall have, 

 in the course of this report, to differ from Prof Bouvier on several minor points and 

 one or two major ones. It is the more fitting, therefore, that I should acknowledge 

 here my great indebtedness to his illuminating report on the Pycnogonida of the 

 " Pourquoi Pas ? " 



The figures illustrating this report have been prepared by Miss Gertrude M. 

 Woodward.
