Aprii 26tli, 1899. — 1) Contribution to Australian Ichthyologj'. By 

 J. Douglas Ogilby. — 2) Botanical. — 3) Description of a new Ophiuran. 

 By H. Farquhar. (Conamunicated by the Secretary.) The name Ophioplocus 

 Huttoni is proposed for this addition tho the Echinoderm Fauna of New 

 Zealand. The genus was previously represented by two species — 0. imhri- 

 catus^ Müll. & Trosch.j frona the Californian coasts, and 0. Esmarkt, Lyman, 

 which ranges throughout the Indo-Pacific Region, occurring on the northern 

 coasts of Australia, New Caledonia, &c. Some supplementary observations 

 and corrections to the author's previous paper are offered. — Dr. F. Tidswell 

 gave a summary of what is known of Tick- or Texas-fever in cattle, and in 

 illustration of his address he exhibited a comprehensive series of preserved 

 specimens, microphotographs, and microscopic preparations of Ticks and of 

 the Tick- fever haematozoon, Pyrosoma higemimim. — Mr. Fletcher exhibited 

 a series of specimens illustrative of, and offered some remarks on, the fauna 

 of the higher portion of the Mt. Koscuisko Plateau (above the tree-line, 

 approximately about 6000 feet), supplementing Mr. R. Helms' general 

 account of the fauna met with from 3000 feet upwards. — Mr. Fletcher 

 exhibited also specimens oî Heîeioporus pictus, Ptrs., from West Australia, 

 part of a collection made by Mr. A. M. Lea, "within 100 miles of Perth." 

 This species is an addition to the Batrachian fauna of West Australia, and 

 is evidently a widely dispersed and characteristic member of the fauna of the 

 Eyrean Sub-region. — Mr. Musson exhibited a clump of the woody galls 

 of the Brachyscelid Cylindroeoccus spiniferus^ Mask., on Casuarina suberosa, 

 gathered at Richmond, which had been forcibly broken open, presumably 

 by predaceous birds for the purpose of extracting the enclosed coccid. 

 — Mr. Froggatt exhibited a collection of Diptera of the sub-family 

 Trypetinae^ commonly known as Fruit -Flies from the damage their larvae 

 do to the ripening fruit, including the American Fruit-maggot, Trypeta pomo- 

 nella, Walsh; a new species of the same genus bred from guavas from the 

 New Hebrides; the Queensland Fruit-Fly, Tephritis Tryoni^ Froggatt; a new 

 species of the same genus bred from bananes from New Caledonia ; and the 

 Mediterranean Fruit-Fly, Haltophora capitata, Wiedman, this being the com- 

 mon species about Sydney ; larvae and pupae were also shown.
