December 6, 1887. 

 Prof. W. H. Flower, C.B., LL.D., F.R.S., President, in the Chair. 



Mr. Howard Saunders, F.Z.S., exhibited, on behalf of the Rev. H. 



A. Macpherson, a specimen of Saxicola isabellina, shot on Nov. 1 1 

 near .\llonby, in Cumberland, being the first recorded occurrence of 

 this species in Great Britain or Western Europe. 



Prof. Bell exhibited the integumentary glands of a Rocky-Mountain 

 Goat (Haplocerus montaniis), which had been taken from either side 

 of the middle line just behind the horns. The glands having, 

 unfortunately, been dried, no information could be given as to their 

 structure, but it was thought advisable to put their presence and 

 position on record.
