in the bladder-walls, it is supposed that the disease is due to the effect of 

 some toxin. Among the possible causes, the -plants Indigo fei'a and Omalanthus 

 are under suspicion ; and experiments with these plants are in progress. — 

 Mr. T. Harvey Johnson, of the Bureau of Microbiology, exhibited and 

 contributed a Note upon an extensive series of Entozoa from horses, and from 

 rats and mice, mostly from New South Wales, some of them now recorded 

 for the first time from this State. — Mr. E. J. God dard, who had recently 

 had the opportunity of assisting Mr. James Murray, Biologist to the British 

 Antarctic Expedition, 1907, to collect Tardigrada and Bdelloid Rotifera, 

 described the method of obtaining these organisms; and he pointed out the 

 opportunity of doing good work awaiting a biologist who would take up 

 the study of these groups in earnest. — Note on Diurnal Variations in 

 the Temperature of Camels By S. Burton Cleland, M. D., Ch. M. (Syd.). 

 — During the examination of a certain number out of 500 camels in the 

 north-west of Western Australia, a wide diurnal variation in their tem- 

 peratures, sometimes of 7° F., was met with. This would seem to be due 

 to the high temperature of the atmosphere during the day, coupled with the 

 fact that camels only visibly perspire at the back of the neck over a small 

 area, and the coolness of the nights. The wide diurnal range suggests a 

 resemblance to cold-blooded animals. — On some rare Australian Gom- 

 phinae [Neuroptera: Odonata]; with Descriptions of New Species. By 

 R. J. Tillyard, M.A., F.E.S. — The present paper brings up to date our 

 knowledge of Australian Gomphinae. Five new species are added to the 

 list, and the male of Austrogomphus risi Martin, of which only the female 

 was known, is described. All six species are of very restricted range, and 

 are remarkable for the extreme diversity and peculiarity of the anal append- 

 ages of the males. The new species are: Austrogomphus nielaleucae, n. sp., 

 found near Sydney; A. bifurcatus, n. sp., from Atherton, N.Q. ; A. dotti, n. sp. 

 from Kuranda, N.Q,.; A. mmiifestus, n. sp., from Kamerunga, N.Q.; and A. 

 comitatus n. sp., from Cooktown, N.Q. Plates are given showing the thoracic 

 colour-pattern, and the appendages of each species. — Studies in the Life- 

 Histories of Australian Odonata. I. Life-History of Petalura gigantea 

 Leach. By R. S. Tillyard, M.A., F.E.S. — The species is one of the few 

 remaining forms of a very ancient family. The life-history is of great interest, 

 since the only other information about the early stages of the group available 

 is a description of the larva of an allied American species {Taohopterix toreyi 

 Selys). Petalura inhabits the mountain bogs and swamps of Central New 

 South Wales, and is apparently confined to a small area, with its centre on 

 the Blue Mountains. The method of pairing, the ovum and larva are de- 

 scribed from observations made, and specimens obtained during November 

 and December, 1908, at Leura, Blue Mountains. The early stages throw 

 considerable light on the relationship of this ancient form to the more 

 dominant present-day families of Odonata. A plate showing the larval 

 exuviae and details of the life-history is given.
