 recorded in the manuscript list.

 panulariina, Sertulariina, and Plumulariina), as well as 

 of Spongiida Hexactinellida have been prepared, and a list 

 of Spongiida Tetractinellida has been commenced. 



The various collections of microscopic preparations of 

 Hydroida and Spongiida, amounting altogether to nearly 

 3,000 slides, have been arranged. The boxes have been 

 labelled with the generic names, and the species arranged 

 alphabetically. Five hundred and thirty-one new prepara- 

 tions of Tetractinellida, and 135 of Hexactinellida have 

 been added to the collection. 



II. — Registration, 

 With the exception of a portion of the Moore Collection^ 

 the specimens obtained during the year, whether by purchase, 

 presentation, or exchange, have been entered in the manu- 

 script registers of accessions, and the register-numbers 

 attached to them. For future reference the date and mode 

 of acquisition, the exact locality where the specimens were 

 obtained, the name of the collector, and any other particulars 

 of interest respecting them, are entered. 



III. — Conservation, 

 The usual work of conservation has been continued by 

 dusting and cleaning, in rotation, the exhibited specimens, 

 placing the study collections of Bird-skins, Shells, Dried 

 Sponges, Echinoderms, and Polyzoa in glass-topped boxes, 

 and renewing the camphor or naphthaline in the wall-cases, 

 store-cabinets, and some of the Insect drawers. Of other 

 work coming under this heading, the following should be 

 specially mentioned : — 



1. Of Mammalia have been mounted for exhibition : a 

 Burchell's Rhinoceros (Rhinoceros simus) ; a Bornean Buffalo

 Thar (Hemitragus jayakari) ; and a Kashmir Stag (Cervus
