The " Zoological Record." 



The Zoological Record for 1893 is now published, and as usual is sold in one bound 

 volume, so that the students of one group of animals are obliged to buy not only 

 the section they themselves need but also all the others. The price of the whole 

 Record, however, is necessarily so high that most people end by buying none at all, 

 which profits neither themselves nor the Zoological Society. To meet this difficulty 

 some of us propose to purchase several copies of the Zoological Record, and to distri- 

 bute the separate parts to subscribers. Although it is not intended to make any 

 profit out of the scheme, it will be necessary to charge rather more for the separate 

 parts than their exact proportional value, since some parts are almost certain to 

 remain unsold. The exact price can only be determined when we know what support 

 we are likely to receive. This scheme applies not only to the volume now issued, 

 but also to previous volumes. Will you permit me, through the medium of your 

 valuable journal, to ask all who may need separate sections from any of these volumes 

 to communicate their exact wishes to me, at the Royal College of Science, 

 London, S.W. ? 



This arrangement is, of course, only a provisional one, as it is hoped that the 

 Zoological Society themselves will soon sell the parts separately. Once more it may 

 be pointed out that this will not damage the Zoological Society, for the present 

 purchasers are mainly Libraries, or such other institutions as need the entire 

 volume.

Merely for Information. 



I have seen " the Rosy Feather Star of our seas " gripping in numbers by their 

 cirrhi to stones below tide marks ; I have seen them drop off singly into the sea 

 as I lifted the stone into the air, and swim away with medusa-like contractions of 

 their arms ; I have also seen them squirming in the silt of the dredge. But I have 

 never seen the "floating colonies" (Natural Science, Dec, 1894, p. 451) of this 

 interesting species. Does your reviewer of Professor Drummond's book mean that 

 " floating colonies " of the Rosy Feather Star are to be found in our seas, or does he 

 wish us to understand that these colonies have an existence only in Drummond's 

 world of pseudo-biology, or in the reviewer's own domain ?

N.B. — The restoration of Archaeopteryx, on p. 443, from Romanes' " Darwin 

 and After Darwin," is a copy of one by Shufeldt which appeared in the Century 

 magazine some eight or ten years ago.
