Catalogues. 1 1 



Mr. F. Walker made great progress with the arrangement of 1856-1861. 

 Lepidoptera Heterocera, not less than seventeen parts (7-23) of 

 his catalogue being published. 



Of a catalogue of Orthoptera only one part (Phasmidse) was 

 prepared by Prof. J. 0. Westwood (1859). The monograph was 

 most profusely illustrated, and the cost of its production 

 was prohibitive (at that time) to the continuation of the 

 catalogue. 



Dr. H. Hagen revised the Termitina (1857); this small part 

 was intended to be the first part of a new edition of the 

 "Catalogue of Neuroptera " prepared by Walker in 185253, 

 but, like the preceding, was not continued. 



For preparation of lists of the British Curculionidse and 

 British Ichneumonidse, Dr. Gray availed himself of the help of 

 J. Walton and Th. Desvignes. 



LISTS AND CATALOGUES. 

 (1856-61.) 



Before completing the references to the publications issued 

 from the Department in 1856-61, it may be useful to introduce 

 some general remarks on the history and character of the 

 Catalogues. 



In 1816 W. E. Leach had prepared a "Systematic Catalogue 

 of the specimens of the Indigenous Mammalia and Birds that are 

 preserved in the British Museum : with their localities and 

 authorities. To which is added a List of the described species 

 that are wanting to complete the collection of British Mammalia 

 and Birds." It was one of the chief merits of Dr. Gray's 

 administration that he not only revived this effort in the third 

 year of his Keepership, but that he gave unremitting attention 

 to the systematic cataloguing of the contents of his Department, 

 and to the publication of the catalogues. Under his fostering 

 care the Zoological Department was, and for many years 

 remained, in this respect far ahead of the other Natural History 

 Departments. In recommending to the Trustees the preparation 

 of catalogues for publication, Dr. Gray had to be careful to 

 present them in an inexpensive form such as would not 

 materially add to the growing annual expenditure of the 

 Department, and would allow of their being freely distributed 

 among zoologists and kindred institutions. Besides, the selling
