MASON AND LEPROY. 323 



Uromastrix from Falco cherrug. 



(Limpets from Hcematopus ostra-gus and Mussels from 



Nyroca marila.) 

 Of Cephalopods the following : 



Squids are said to be taken by Gannets (Sulidce) and Tropic 

 birds (Phcethontidce) \ 



Cuttle fish by Frigate birds (Fregatidce), and Gannets (Suli m 

 dee) ; 



Cephalopods generally by Sterna fu'iginosa, and by the Pro- 

 celliformes. 



Coelenterata. -Acephala or jelly-fish are said to be taken by 

 L^'mosa lapponica and the Procelliformes. 



Annelida. Leeches (Hirudinid) are said to be taken by 

 Bubulcus coromandus from crocodiles. 



Myriopods. Centipedes are possibly beneficial, but do not form 

 any considerable proportion of the food of any bird, in fact, they 

 are seldom eaten at all. They are recorded as eaten by Pe'rophila 

 salitoria, Brachypternus aurantius, Bichoceros bicornis, Glaucidium 

 radiatum, Circaetus gallicus, Eupodotis edwardsi, Sypheotis au. 

 rita, and S. bengalensis. 



I have taken them from the stomachs of the following : 

 Corvus microrhynchus, C. splenadens, Dendrocitta rufa, Crateropus 

 canorus, Centropus sinensis. The Bustards (Otididce) are also said 

 to eat Myriopods. 



Insects. The main work in economic entomology lies naturally 

 in accumulating facts about the food of birds both by observations 

 in the field and by the examination of the stomach contents in the 

 laboratory. This is the basis on which every thing depends- our 

 facts. It can, however, be understood readily that these accu- 

 mulated facts are of no immediate practical value until we have 

 settled finally up to the present time the economic importance of 

 the food taken, speaking more especially from a Zoologica 1 point 

 of view
