450 D«. Av. E. HOYLE OX CEPiiALOPODS [May 7, 



In the Schonbi^unn Zoological Gardens — the most beautiful of 

 all — not only the Polar Bears but also the Brown and Black Bears 

 are giAen large water-tanks in which they spend most of the day 

 very happily, being by nature water-loving animals and not 

 frequenters of " bear-pits." 



Although the buildings in many Continental Zoological Gai'dens 

 were originally modelled on those in Regent's Park, our neighbours 

 had now perhaps gone ahead of us in some directions. While we 

 need not follow them in the fanciful design and coloured decoration 

 of some of their modern buildings — these things being a matter of 

 temperament and taste — we should do well in the future to turn 

 our attention more carefully to improved methods of warming, 

 lighting, and ventilation, to convenience in feeding and cleaning, 

 and particularly to the question of admission of sunlight and 

 air. 



Mr. Trevor-Batty e, in conclusion, expi'essed his sense of the 

 courtesy, kindness and ready accessibility of the Directors of 

 the Gardens visited. 



The following papers were read : — 



1. The Marine Fauna o£ Zanzibar and East Africa, from 

 Collections made by Cyril Crossland in 1901-1902.— 

 The Cephalopoda. By William E. Hoyle, M.A., 

 D.Sc* 



[Received April 26, 1907.] 

 (Plate XX. t and Text-figures 128-137.) 



The collection of Cephalopoda from Zanzibar placed in my hands 

 by Mr. Cyril Crossland is not a large one, but its investigation has 

 brought out several points of interest. 



Of the forms here recorded five were among the collections 

 made by Professor Herdman in Ceylon (Hoyle, : 05), whilst four 

 are also found in the Red Sea, thus indicating considerable homo- 

 geneity in the CephaloiDoda of the northern and north-eastern 

 parts of the Indian Ocean. 



Certain Octopod embryos exhibited very clearly the bristle-like 

 processes noticed but not yet fully described by Chun (: 04) and 

 myself ('05 a). I have, therefore, taken the opportunity of giving 

 an account of them with illustrations. 



I have to record my thanks to Mr. Crossland for the opportunity 

 of studying the collection, and to Miss Ethel M. Ciirwen, F.Z.S., 

 for making some of the drawings. 



The numbers in square brackets refer to my own register of 

 specimens examined.
