PREFACE . 



WHKS, in 1901, the Expedition of the 8.8. 'Discovery,' under Captain Scott, R.X., 

 was sent to the Antarctic Regions, the Trustees of the British .Museum gave their 

 ntstance to this national enterprise by allowing the cases containing the natural 

 history specimens which might lie obtained by the Expedition to be sent to the 

 Natural History Museum for unpacking and sorting. They further undertook to 

 publish a detailed report on the collections so obtained, under the superintendence 

 of the Director of the Natural History Departments. 



8ome of the most important collections have leen dealt with by naturalists who 

 were mem tars of the Expedition. Thus, the Mammals* and -Birds* arc dcscrilxxl by 

 Dr. Edward A. Wilson, tlie Isopoda and Pycnogonida* by Mr. T. V. Hodgson, and 

 the Rocks* (in relation to Field Geology) by Mr. H. T. Ferrar. Other groups have 

 been dealt with by members of the staff of the Natural History Dcjmrtments of 

 the British Museum : Mr. Boulenger describes the Fishes* ; Mr. E. A. Smith, the 

 Qtttropoda,* Lamcllibranchia,* and Brachiopoda* ; Mr. Jeffrey Bell, the Echinoderma* ; 

 Dr. Caiman, the Crustacea Decapoda,* and the Cumacea* ; Mr. Kirkpatrick, the non- 

 . al.iireous Sponges*; whilst Dr. G. T. Prior has prepared a petrographical description 

 of the Rock-specimens.* 



It has been necessary to obtain the assistance of other specialists in order to deal 

 with the rest of the collections. So far as the latter group of contributors is 

 concerned, the following is a list of the subject-matters, together with the name of the 

 naturalist who has undertaken the work in each case :
