 has been completed ; other Jurassic and Cretaceous Echinoids of 

 England have been re-registered and re-labelled ; and the whole 

 of the exhibited series of British Echinoids has been re-arranged. 

 Specimens illustrating some of the Girvan Cystids have been ex- 

 hibited. The revision of the Palaeozoic Asteroidea continues. 

 Various Echinoderms preserved in pyrites have been treated and 

 soaked in melted paraffin to check decomposition. 



The slip-catalogues of specimens studied or exhibited, of all 

 Blastoids, and of genera and species of other classes, have been 

 continued. 



Number of specimens of Echinodernia registered : — Echino- 

 idea, 297; Asteroidea, 19; Crinoidea, 442; Blastoidea, 90; Cys- 

 tidea, 599; Total, 1,447. 



Annelida (Gallery 8 and Workroom). — The accessions regis- 

 tered, labelled and incorporated include specimens of Ottoia,

 Silurian', and Devonian of IN". America (G. J. Hinde coll.); Con- 

 chicoli-tes from the Silurian of Gotland (Bather coll.); Spirorbis 

 from the Upper Devonian of Iowa (Fenton coll.); Serpula from 

 the Oxfordian of Villers-sur-mer (Rakowski coll.). A number 

 of Tentaculites have been re-regisCered on their transference 

 from Mollusca. 



A specimen of Protoscolex latus, a new Oligochaet from the
