72 ACCOUNTS, ETC., OF THE BRITISH MUSEUM. 



The revision o£ the MS. Catalogue of Asteroidea has been com- 

 pleted and progress has been made with that of the Echinoidea. 



Worms. 



A few specimens obtained during the year have been named and 

 incorporated. The " Terra Nova " collection of Myzostomida has 

 been worked out by Dr. C. L. Boulenger, and a report on them is 

 in preparation. 



The collections of Nemertinea, both in spirit and mounted as 

 slide-preparations, have been re-arranged, the former being re- 

 spirited. The classification and nomenclature have been largely 

 brought up to date, and a MS. list has been drawn up. There 

 remain, however, many unnamed specimens. 



The numerous additions to the Helminthological collections 

 have been accommodated, as far as possible, in the cases in the 

 spirit building, with the usual difficulties owing to the congested 

 condition that prevails there. Many useful additions have been 

 made to the slide-collection of parasitic worms. 



POLYZOA. 



The " Discovery " collection (partly worked out by Mr. H. W. 

 Burrows) and the " Terra Nova " collection have been entrusted to 

 the Hon. Mary E. Palk to describe, and this work is now well in 

 progress. 



Anthozoa. 



Before the shortage of attendants became acute the Ccral 

 Gallery was completely cleaned. Owing to the large quantity of 

 glass almost incessant attention is required in this part of the 

 collection. 



Hydrozoa. 



Captain A. K. Totton, who is in charge of this group, has been 

 on active service since the beginning of the war. 



127 specimens of Hydroida acquired previously to 1915 have 

 been registered and incorporated. 



PoRiFERA (Sponges). 



The whole spirit-collection of sponges has been re-spirited. To 

 prevent evaporation the method of sealing each bottle with a mix- 

 ture of vaseline and beeswax has been adopted. 



The working out of the sponges collected by the " Terra Nova " 

 in the Antarctic region has been continued. Those collected by the 

 same expedition in the New Zealand area and in localities other 

 than Antarctic have been entrusted to Prof. A. Dendy, F.R.S., and 

 Mr. R. W. H. Row for description. 



Protozoa. 

 The "Terra Nova " collections of Foraminifera, including sea- 

 bottom samples likely to contain these organisms, have been entrusted 

 to Messrs. E. Heron-Allen and A. Earland to work out.
