up the Gambia River to the end of its navigable waters, and specimens of 

 the heads of those obtained were laid on the table. A collection of Gambian 

 birds was also exhibited. — A communication was read from Mr. L. A. Bor- 

 radaile, F.Z.S., in which it was shown that both genera [Coenobila and 

 Birgus) of the Pagurine Land-Crabs [Coenobitidae) are hatched in the Zo'éa- 

 stage. — Dr. W. G. Ride wood read a paper on the relations of the efferent 

 branchial blood-vessels to the circulus cephalicus in the Teleostean Fishes, 

 based upon an examination of specimens of sixty-one species. He demon- 

 strated the great variation that is met with in the arrangement of the efferent 

 vessels, and discussed the possibility of utilizing the characters as a means 

 of arriving at a natural classification of the group. — Mr. G. A. Boulenger, 

 F.R.S., read a paper on the Reptiles, Batrachians, and Fishes collected by 

 the late Mr. John Whitehead in the interior of Hainan. The collection con- 

 tained specimens of 15 species, embracing 4 species of Reptiles, 6 of Batra- 

 chians, and 5 of Fishes. Of these, 2 species of Reptiles, 3 of Batrachians, 

 and 3 of Fishes were described as new. — A communication was read from 

 Dr. A. G. Butler, F.Z.S., on a collection of Butterflies made by Mr. Richard 

 Crawshay in British East Africa. Sixty-eight species were enumerated and 

 remarked upon, of which four were described as new. — A second communi- 

 cation from Dr. Butler contained a list of a small collection of Butterflies 

 made by Capt. Hobart, of the Grenadier Guards, in the Nandi District [of 

 the Uganda Protectorate. Of the 17 species represented in the collection, 

 one [Cymothoe Hobarti) was described as new. — A communication was read 

 from Mr. J. Y. Johnson, C.M.Z.S., containing a note on the habit "and 

 mode of growth of the Corals belonging to the genus Pleur oc or allium. — Mr. 

 W. E. de Winton, F.Z.S., made some supplementary remarks to those 

 published in the 'Proceedings' for 1898 (p. 900), on the moulting of the 

 King Penguin [Aptenodytes Pernianti) now living in the Society's Gardens. —

 mology. No. 9. New Species of Carabidae with Notes on previously described 

 Species. By Thomas G. Sloane. — 3), 4), and 5) Botanical. — 6) Résumé 

 of what is known of the Life-history of the Tick Fever Parasite. By R. Greig 

 Smith, M.Sc. , Macleay Bacteriologist. The youngest recognised form of 

 Apiosoma bigeminum is a minute body which changes its shape as it moves 

 about in the blood corpuscle or serum. This is succeeded by an amoeboid 

 form which enlarges and ultimately becomes the mature pearshaped body. 

 It is probable that the so-called vacuole of the mature form is in reality a 

 capsule. The parasite is found in cattle, but it is possible that it may attack 

 other animals, since in these a similar parasite has been found. The rôle of 

 the tick as an infecting agent is discussed. — Mr. Stead exhibited some 

 interesting specimens of a Phasmid from Tanna, New Hebrides ; also a pre- 

 paration of the crustacean , Ibacus Peronii, Leach, from Port Jackson, showing 

 both ventral and dorsal aspects and the oral appendages. — Mr. H. S. Mort 

 exhibited an unusually large emu egg measuring ^/^X^/i inches, obtained 

 near Byrock.
