60 ACCOUNTS, ETC., OF THE BRITISH MUSEUM. 



A Report on the Cephalopoda 'o£ the British Antarctic (" Terra 

 Nova ") Expedition, by Miss A. L. Massy, has been published, and 

 the specimens have been returned to the Museum. 



Lieut.-Col. H. H. Godwin-Austen, F.R.S., has continued his 

 work on the Oriental land and freshwater Mollusca. 



The death, on July 22nd, 1916, of Mr. E. A. Smith, I.S.O., 

 formerly Assistant-Keeper, was a very serious loss to the Depart- 

 ment, to which he continued to give valuable aid, after his retire- 

 ment in 1913, almost to the end of his life. 



Myeiopoda and Arachnida. 



Special attention was given to parasitic Acari during the year, 

 and a number of species of economic importance were dealt with, 

 including some rare forms, such as the Demodex of the horse, the 

 Chorioptes affecting the feet of sheep, &c. A Guide to the species 

 of Arachnida and Myriopoda injurious to Man has been prepared 

 and is now in the press. The arrangement of the Koch Collection 

 was continued but has been somewhat impeded by the delay in 

 delivering the glass tubes necessary for this work. 



Crustacea and Pycnogonida. 



A few spirit specimens in the exhibited series have been refilled 

 and resealed. 



The periodical refilling and cleaning of the bottles in the Spirit 

 Collection has been carried on with many interruptions due to lack 

 of assistance. 



A large collection presented during the year by Mr. A. 0. Walker 

 has been roughly sorted and stored to await proper arrangement 

 and registration. With this exception the specimens received have 

 all been registered and incorporated in the general collection. It has 

 not been possible to make any progress with the registration of the 

 Norman Collection or of the other collections alluded to in former 

 Returns. 



Echinoderma. 



The respiriting of several groups of Echinoderms has been 

 carried out. 



A small but interesting collection from South Australia, received 

 some time since, has been determined and will shortly be incorporated. 



The Index Catalogue to the collection of Microscopic slides, 

 illustrating this and other groups mentioned in last year's Return, 

 has been completed. 



The revision of the MS. Catalogue of Echinoidea has been 

 finished, and progress ^las been made with that of the Ophiuroidea. 



Worms. 



Mr. Baylis, the Assistant in charge of part of the collection of 

 Worms, is absent, being engaged in war work at the R. Naval Hospital, 

 Haslar.
