Hall to the North Hall where it is better seen than in its 

 former position. The seventeen preparations of the dentition 

 of the Horse at different ages have also been transferred to 

 the North Hall. 



A series of 72 Insects of various kinds from Mashonaland 

 has been presented by Mr. Guy A. K. Marshall to show the 

 remarkable community of pattern and coloration that may be 

 exhibited by unrelated insects in the same district, and con- 

 stitutes an important addition to the '- Mimicry Case." 



Some new specimens, numerous figures, and a map showing 

 the "Tsetse Belts," have been added to the "Tsetse Fly 

 Case;" a fine specimen of the gigantic deep-sea Hydroid 

 Branchiocerianthus has been placed on exhibition, and much 

 work has been done in the way of respiriting and remounting 

 such of the anatomical preparations in the Entrance Hall as 

 w^ere in need of attention. 



From the over-crowded cases in the Fish Gallery 900 

 specimens have been removed as unsuited for exhibition, and 

 have been placed in the new store-room in the Basement. 

 .More than a hundred of the remaining specimens have been 

 restored and coloured according to published coloured figures 

 and descriptions ; and as an experiment for ascertaining the 

 most satisfactory means of displaying specimens of Fishes, 

 one of the wall-cases has been fitted up with a sloping back- 

 ground, upon which have been set out selected specimens, 

 mostly coloured, of Berycoid and Percoid Fishes. The most 

 striking additions to the gallery are coloured casts of the 

 great Blue Shark (C ar char o don) and Lamna, mounted upon 

 a special table, with specimens of the real jaws and teeth of 

 the same species ; a stuffed specimen of the newly-discovered 

 deep-sea shark of Jcxpan (Mitsukurina) ; a set of preparations 

 of Lampreys and Hag Fishes in a special centre-case ; enlarged 

 restorations of the Ostracoderm Fishes, Ce2:)halaspis, Pterasjns, 

 and Brepanasjns, based upon specimens in the Geological 

 Department, and published descriptions and figures ; and 

 enlarged vrax-models of the Ascidian Tadpole and of the 

 free-swimming Ascidian FritiUaria, which have been added 

 to the " Amphioxus Case." 



Plaster casts have been prepared of specimens of the 

 Salmon, Grilse, Bull-trout, Sea-trout, Leven Trout, Suther- 

 land Trout, Pollan, and Char, and these it is proposed to 

 colour according to water-colour sketches made of the fresh 

 fish immediately on their arrival.
