received from M. A. Milne-Edwards, and remarked on the assumption of 

 antenniform characters by the left ophthalmite shown in this specimen. 



A paper was read by Mr. W. F. Kirby, Assistant in the Zoological 

 Department, British Museum, entitled " A Revision of the Subfamily 

 LibellidincE, with descriptions of new Genera and Species." The last 

 compendium of this group was published by Dr. Brauer in 1808, in which 

 forty genera were admitted. Mr. Kirby now raised the number to eighty- 

 eight, all fully tabulated and described in his paper, which likewise included 

 descriptions of fifty-two new species. Mr. Kirby gave a short sketch of the 

 characters of the LibelluUna, and more especially of the neuration, which 

 he considered to be of primary importance. 



Mr. R. Bowdler Sharpe read the third part of his series of notes on the 

 Hume Collection of Birds, which related to Syriiium maingayi, Hume, and 

 to the various specimens of this Owl in the British Museum. 



A communication was read from Mr. A. Smith Woodward, on the 

 presence of a canal-system, evidently sensory, in the shields of Pteraspidian 

 fishes. Mr. Woodward described a specimen which seemed to prove that 

 the series of small pits or depressions upon tho shields of these ancient 

 fishes, observed by Prof. Ray Lankester, are really the openings of an 

 extensive canal-system traversing the middle layer of the shield. 



A second communication from Mr. A. Smith Woodward contained some 

 notes on the " lateral line " of Squaloraja, in which it was shown that the 

 "lateral line" of this extinct Liassic Selachian was an open groove sup- 

 ported, as in the Chimseroids, by a series of minute ring-like calcifications.

 two Red-spotted Lizards, Eremias rnhro-jmnctata, obtained at Moses' Well, 

 in the Peninsula of Sinai, and presented to the Society by Mr. G. Wigan; 

 and to a small scarlet Tree Frog, Dendrobates typographus, from Costa Rica, 

 presented to the Society by Mr. C. H. Blomefield.

A communication was read from Mr. A. 0. Hume, C.B., containing
