Other variations of this species were also shown, but it was 

 pointed out that col our- variations were very rare, although 

 partial albinism sometimes occurred. The remarkable variation 

 above mentioned had been described and figured in ' British 

 Game-Birds and Wildfowl' (pi. xxi. fig. 2, 1912). 



Mr. Ogilvie-Grant also exhibited a series of col our- variations 

 of the Common Partridge {Perdico perdioc), amongst which was 

 the well-known chestnut form, P. montana Brisson. This form 

 appeared to be comparable to the rufous variety of the Bed-leg, 

 but in this instance the variation was comparatively common, 

 having been first described in 1760 from the mountains of 

 Lorraine, and subsequently obtained in almost every county in 

 England and some parts of Scotland. 



Lastly, specimens of the Bearded Partridge (P. dcmrica), from 

 Manchuria, were exhibited. This species is now being sold in 

 large numbers in the London markets, and the exhibitor had 

 recently purchased a beautiful pale grey variety, which, however, 

 had the black horseshoe patch normal. 



Prof. H. Maxwell Lefroy, M.A., F.Z.S., Curator of Insects, 

 exhibited a specimen of Sphodro mantis guttata, which had been 

 bred from the egg in the Caird Insect House and had attained 

 maturity during March. He discussed the advantage of breeding 

 stick insects to supply a substitute for meal-worms, and read notes 

 on insects that had been bred in the insect house. 



Mr. R. Lydekker, F.R.S., F.Z.S., presented a paper entitled 

 " The True Coracoid," in which he stated that the element in 

 birds a.nd post-Triassic reptiles universally known as the coracoid 

 is the homologue of the human coracoid process, and its equivalent 

 the true coracoid of the monotremes and mammal-like reptiles. 



.Dr. F. E. Beddard, M.A., F.R.S., F.Z.S., Prosector to the 

 Society, read a paper dealing with certain points in the anatomy 

 of the Cestode genera Amabilia and Dasyurotcenia. 



Mr. Bruce F. Cummings read a paper " On new Species of 

 Polyplax (Anoplura) from Egypt." This paper contained a 

 s}^stematic description of two new species of louse based on a 

 large supply of material in spirit collected on Acomys cahirinus 

 Des., and forwarded by the Department of Public Health in 

 Egypt to the Lister Institute, by whom they were subsequently 

 presented to the British Museum. 



Both the new species were fortunately collected in large numbers 

 in all stages of development, and an account of the larvfe conse- 

 quently has been prepared. Unfortunately the specimens were 

 in a poor state of preservation, so that a study of the soft parts 

 was not possible.
