most exciting capture was the beautiful orange butterfly, 

 Delias inferna, not previously found south of Cape York. 

 Beetles were scarce, although no opportunity was lost of 

 searching under the rapidly-decaying logs and other likely 

 places. Several species of large land-shells were, however, 

 obtained, especially after the rainy season commenced, while 

 along the banks of the shallow water-courses were often seen 

 heaps of a large bivalve, indicating a recent feast by the 

 blacks. Collecting in the scrub had to be relinquished in time 

 to reach camp at sunset, as it was impossible to travel in such 

 country after dark.

OsTRACODA. — Several interesting species of Ostracoda, 

 collected near Yering, were exhibited by Mr. J. Searle at the 

 November meeting of the Club. These little bivalved Crustacea 

 are very interesting to the student of minute animal life. Their 

 distribution in Victoria is as yet only slightly known, and when 

 this group is fully worked out it will show that we possess a 

 very rich ostracodal fauna. At present we owe our knowledge 

 of the Victorian species of ostracoda to the work of the Rev. 

 R. L. King, Dr. G. S. Brady, and Dr. G. 0. Sars. These 

 workers, however, examined material which came from other 

 parts of AustraUa. The commonest form represented in the 

 present gathering is Cypris mytiloides, G. S. Brady, a widely 

 distributed species, and also a very variable one. It differs 

 from other known species of the genus in its peculiar caudate 

 extremity, in which it seems to resemble Macrocrypus. Dr. 

 G. S. Brady, however, is convinced of its relationship to the 

 genus Cypris, as seen in the structure of the animal. Another 

 common species found in this sample is the cheerful little 

 Cypridopsis minna, King, sp., which, in its rather vivid green 

 carapace with lighter bands of variegation, is seen spinning and 

 paddling at a great rate through the water. A larger species of 

 ostracod is also present in some numbers, probably allied to 

 Cypridopsis, and apparently new, but may, perhaps, be 

 eventually identified with King's " Cypris " carinata, although 

 his figures and description, being not too satisfactory, will 

 render the comparison rather difficult. A fourth species 

 occurring here is a form of Notodromas. It agrees somewhat 

 closely with Brady's N. fuscatus, from the Tweed River, New 

 South Wales. N. fuscatus is of a brownish colour, whilst ours 

 is green, but what is a more important difference is that the 

 carapace in our form is more angulate, seen from the side, than 

 in N. fuscatus. In the latter respect it shows some affinity with 

 N. fenestratus, of King. — F. Chapman.
