groups of Nematoda, the series of Gnathostomida© having been 

 much improved, and certain sections of the Ascaridae worked over- 

 with a view to their more accurate determination and systematic- 

 arrangement. The determinations of many other specimens^ in 

 the old collection have also been checked or revised ; some of 

 these specimens bear labels on the outside of the bottles, which 

 have become almost illegible from fading and discoloration; in 

 such casea the- original data have been copied on to inside labels 

 so that they may be more permanently preserved. 



Brachiopoda. 



A beginning has been made of the determination of unnamed 

 forms in the collection. Mr. J. W. Jackson has kindly under- 

 taken the study of this material. 



COELENTERATA, 



The study collection of Hydroida has been respirited through- 

 out, and the Norman collection sealed in addition. Two hundred 

 microscopical preparations of Hydroida have been made and 

 incorporated in the study slide collection. 



Several small collections have been determined, catalogued 

 and incorporated. 



The study collection of dry Fungid corals has been reviewed 

 and rearranged, many undetermined specimens having been 

 named.

 the respiriting of the collection has been carried on.
