HARDWICKE'S SCIENCE-GOSSIP. 



S. Sturt. — You cannot do better than get Gosse's " Marine 

 .Zoology," 2 vols. Landsborough's " Sea- Weeds " (with 

 coloured plates) would help you to the alga?. 



A. J. Shaw.— Get Dr. Cooke's " British Fungi," price 6s. 

 Send us another specimen and we will name it for you. 



W. D. — We do not undertake to name exotic shells or speci- 

 mens. 



A. H. Fisher.— It is a popular fallacy that the cuckoo sucks 

 the eggs of other birds. The favourite food of the cuckoo is 

 large caterpillars, which it consumes in numbers. Possibly 

 the idea as to its egg-sucking habit may have arisen because 

 the cuckoo is often chased by small birds, the latter possibly 

 mistaking it for a hawk. See chapter on the cuckoo in Harting's 

 new book " Sketches of Bird Life," and the article ' Cuckoo ' in 

 the last edition of the " Encyclopaedia Britannica,"by Professor 

 Newton. The goatsucker obtains its name from the current 

 belief in Italy that it sucked the goats, hence its specific ornitho- 

 logical name of Caprimulgus. 



T. H M. — From your sketch we judge that your zoophyte 

 is not a Sertularian, but a Polyzoon. It is very like Valkeria 

 imbricata. 



T. H.-We do not undertake to return the specimens sent to 

 us to be named. All our answers are gratuitous, and are in- 

 tended to help students, not to do their work for them and 

 save them trouble (although many of the queries sent us are for 

 the latter reason). You can procure a cyanide bottle, for 

 placing your insect captures in, from any dealer in entomological 

 apparatus. You will find full instructions in " Collecting and 

 Preserving Natural History Specimens," edited by J. E. Taylor, 

 price 3-r. 6d. See chapters in the above by Dr. Knapp and 

 E. C. Rye. 



F. W. Crick. — Many thanks for specimens of Clepsine 

 hyalhia. Answer next month. 



A Draper. — Could you send us another specimen of the 

 parasite in Andonta? 



A. Beales. — Rimmer's "Land and Freshwater Shells," con- 

 tains photographs of every species. Price ior. 



Mrs. Bell. — The best work on grasses is the volume of 

 Sowerby's " Botany " on Graminese, which may be obtained 

 separately. It has a coloured illustration of every British 

 species. 



E. J. G. — You will find a good summary of Gadow's paper on 

 the colours of the feathers of birds in the Proceedings of the 

 Zoological Society for last year.
