Henry W. Tyler, and remarkable for the hen bird having gradually assumed 

 the (now nearly complete) dress of the male ; and to a young pair of singular 

 Deer of Mantchuria called Pere David's Deer, Cervus Davidiaiius, purchased 

 November 16th. 



Dr. F. Leuthner read an abstract of a memoir which he had prepared 

 on the Odontolahani, a subfamily of the coleopterous family LiicanidcB, 

 remarkable for the polymorphism of the males, while the females remained 

 very similar. The males were stated to exhibit four very distinct phases 

 of development in their mandibles, which the author proposed to terra 

 " priodont," "amphiodont," "raesodout," and " telodont." These forms 

 were strongly marked iu some species ; hut in others were connected by 

 the insensible gradations, and had been treated by the earlier authors as 

 distinct species. The second part of the memoir contained a monograph of 

 the three known genera which constitute the group Odontolahini. 



Mr. E. B. Poulton read a memoir on the structure of the tongue in 

 the Marsupiaiia. The tongues of species of nearly all the important groups 

 of this subclass were described in detail. It was found possible to classify 

 the tongues in three divisions. Of these Htilmaturus was the type of 

 the lowest, Phalangista of the intermediate, and Perameles of the most 

 advanced division. 



Mr. J. Wood-Mason read a paper on the Emhiida, a httle-knovvn family 

 of insects, on the structure and habits of which he had succeeded in making 

 some investigations during his recent residence in India. He came to the 

 conclusion that the Embiida: undoubtedly belong to the true Orthoptera, and 

 are one of the lowest terms of a series formed by the families AcridioidecB, 

 LocustidcE, Gryllidce, and Phasniatida. 



Mr. G. A. Boulenger read an account of a collection of Frogs made 

 at Yurimaguas, Huallaga River, Northern Peru, by Dr. Hahnel. The 

 collection contained examples of eighteen species, eight of which were 

 regarded as new to science. 



Mr. W. F. R- Weldon read a paper on some points in the anatomy of 

 Phcenicopterus and its allies. An account was given of the air-cells of the 

 Flamingo, which were shown to differ from those of Lamellirostres, and to 

 agree with those of Storks— (1) in having the praebronchial air-cell much 

 divided, (2) in the feeble development of the posterior intermediate cell, 

 and (3) in the great size of the abdominal cell. The pseudepiploon was 

 also shown to differ from that of Lamellirostres, and to agree with that of 

 Storks, in extending back to the cloaca. A detailed comparison between 

 the muscles, especially those of the hind limb, gave the same results. The 

 larynx, however, being Anserine, and the skull intermediate, the position 

 expressed by Huxley's term Amphimorphm was considered fully justifiable. 



Mr. Sclater read a paper, in which he gave the description of six 

 apparently new species of South-American Passeres.
