under the charge of Dr. Gray, Mr. S. 0. Ridley, Mr. A. Dendy, 

 and Mr. R. Kirkpatrick, who have described various portions of 

 it, and have attended to the general preservation and arrange- 

 ment. In 1848, Dr. Gray published a " List of the Specimens of 

 British Animals in the British Museum. Part. II. Sponges " ; 

 in 1879, Dr. H. J. Carter drew up a manuscript catalogue of 

 Sponges in the British Museum. The collection is now in a 

 good state of preservation and arrangement, manuscript cata- 

 logue lists of the greater part having been made by Mr. R. 

 Kirkpatrick. 



Hydrozoa. — Very little descriptive work in connection with 

 this class of animals has been done by the members of the staff in 

 whose charge they have been from time to time, namely, Dr. J. 

 E. Gray, Mr. 8. O. Ridley, Mr. J. J. Quelch, and Mr. R. Kirk- 

 patrick. In 1848, Dr. Gray published a "List of the Specimens 

 of British Animals in the Collection of the British Museum. 

 Part I. Centronix ; or, Radiated Animals." Mr. R. Kirkpatrick 

 has described small collections, and drawn up manuscript cata- 

 logue lists of the collections of Hydroida, Hydrocorallinse, 

 Medusae, and Siphonophora ; he has also arranged the collection 

 in its present order, both the exhibited portion and the study 

 series. 



Polyzoa. — In 1848, Dr. Gray published a list of the British 

 Polyzoa in the collection in his " List of British Animals, etc." 

 This part of the collection was chiefly studied by Mr. George 

 Busk, who, in 1852, wrote the first part of the Catalogue of the 

 Polyzoa in the British Museum, published by the Trustees. The 

 second and third parts, by the same author, were published in 

 1854 and 1875 respectively. Dr. J. E. Gray, Mr. S. O. Ridley, 

 Mr. J. J. Quelch, and Mr. R. Kirkpatrick have been in charge 

 of the collection of Polyzoa from its formation until the present 

 time. 



Brachiopoda. — -This part of the collection has not been 

 specially worked at by the various curators under whose charge 

 it has been placed, but all the specimens have been carefully 

 preserved and labelled. The collection is now completely named 

 and arranged in accordance with the most recent monographs, 

 and a manuscript catalogue of its contents has been drawn up 

 by the Assistant at present in charge of it, viz., by Mr. R. 

 Kirkpatrick. 



Tunicata. — Like the preceding group, this class of animals, 

 formerly considered as Mollusca, has never been systematically
