out to him as distinguishing the subordinate groups of that exten- 

 sive family. 



January 25. — A paper entitled " Observations on the structure 

 of the tarsus in the Tetramerous and Trimerous Insects of the 

 French Entomologists," was read by W. S. MacLeay, Esq. M.A. 

 F.L.S. 



February 3. — Mr. Bicheno exhibited a specimen of Procellaria 

 pelagica^ Linn., which had been shot in the neighbourhood of 

 Newbury, in Berkshire, In November last. This is one of the 

 rare instances in which this oceanic bird has been met with so far 

 inland. 



Mr. V^igors exhibited a diagram representing the five orders of 

 Ornithology, and thfe circular series in which they return into 

 themselves, according to the views which he had represented in 

 a paper " On the Affinities of.Birds,^V laid before the Club on the 

 9th of December, 1823, and subsequently read before the Lin- 

 nean Society during the course of the last year. He explained 

 the nature of the typical characters by which these five orders 

 are separated from each other, and at the same time the affinities 

 by which they are connected together. He signified his intention 

 of occasionally illustrating this subject both in the more com- 

 prehensive and more minute groups of Ornithology, according 

 as the leisure of the Club will permit, by exhibiting specimens of 

 those birds in which the distinguishing characters as well as the 

 connecting affinities are most fully developed.

 mens of several subjects of Zoology collected in the Indian ocean,
