240 THE ZOOLOGIST. 



mauy are scattered through ' systematic ' papers where they are easily 

 overlooked, that I have thought it advisable to collect and classify, as a 

 supplement to the 'Summary of the Deep-Sea Zoological Works' pub- 

 lished iu these memoirs in 1899, all such observations as have been 

 reeorded since I first became connected with the ship, together with many 

 hitherto unpublished facts selected from my Journal." The branches of 

 zoological knowledge to which contributions are made are — " Illustrations 

 of Commensalism "; Notes on Sexual Characters ; Pairing and Viviparity 

 among Marine Animals, and on the sounds made by certain of them; 

 Notes on Stalk-eyed Crustacea; Instances of Protective and Warning 

 Colouration : the Phosphorescence of certain Marine Invertebrates ; 

 Peculiarities of Food, &c. We wish that this condensation was made by 

 authors from other publications ; biological facts do remain very often 

 buried except to the most industrious students, and even then their know- 

 ledge is necessarily of a personal equation. 



Messrs. Friedlander & Sohn, of Carlstrasse II, Berlin, have just 

 brought out a new and revised edition of their ' Zoologisches Adressbuch.' 

 Mention has been already made in these pages as to the usefulness to all 

 naturalists of this universal directory, and in its present revised form it 

 will be still more serviceable. We still prefer, however, the usual and 

 general method of allowing naturalists to communicate their own proper 

 addresses, for we notice that the zeal of the compiler for change has in 

 some cases outrun his discretion. However, all naturalists who have 

 reason to correspond with others — and who has not ? — will appreciate this 

 publication. 



We have received the Report for the year 1900 of the Ghizeh Zoological 

 Gardens, near Cairo, written by the Director, Capt. Stanley S. Flower. 

 The following animals were born in the Gardens and successfully reared 

 during 1900 :— 



Two Black Lemurs {Lemur macaco}. 



Two Mongoose Lemurs (L. mongoz). 



Seven Dorcas Gazelles (G^aseZZa doj'cas). 



Three Angora Goats [Capra hircus). 



One (Three-quarter bred) Ibex {C. nubiana). 



Two Hedjaz Sheep [Ovis aries steatopyga). 



Three Guinea Pigs {Cavia porcellus). 



Three Turtle Doves {Turtur senegalensis). 



Nine Laughing Doves {T. risonus).
