the common cockle (Chiones scalar ma J on which Cladophora, 

 sp., was growing. The shells were collected near the mouth 

 of the American River, Kangaroo Island, from a large area 

 of clean tide-scoured sand. The alga was only found on 

 living shells or those of recently-dead fish, and only growing 

 healthily in the former case. Live cockles are the only 

 objects to which the Cladophora can fix itself in this 

 area. The alga was always fixed at the posterior end near 

 to the dorsal hinge. This is the portion of the shell nearest 

 the surface of the sand, but it is also near the exhalent syphon. 

 The suggestion was offered that the alga might benefit by 

 such proximity to the current of water leaving the animal, 

 which would be richer in carbon-dioxide from its passage over 

 the gills of the animal and in nitrogenous material voided 

 into the cloacal cavity. Mr. Edwin Ashby showed some 

 Jonathan apples, which were clean when gathered, but had 

 after a time become spotted with "bitter pit"; also the fol- 

 lowing birds: — Phaps chalcoptera, Lath. (Bronzewing 

 Pigeon) ; Cosmopelia elegans neglecta, Mat. (Brush Bronze- 

 wing), from Karoonda; H.ypotaenidia philippensis australis, 

 Pel. (Eastern Buff-banded Rail); Porzanoidea plumbea 

 immaculata, Swain. (Eastern Spotless Crake); Porzana 

 fluminea whitei, Mat. (Southern Spotted Crake), from near 

 Paradise, 19/12/18, where the two preceding species and 

 Zapornia pusilla paluHris, Gld. (Eastern Little Crake), have 

 this season been very numerous, also from a waterhole in 

 the mallee, near Karoonda; Myzantha melanosis, Wilson 

 (Black-eared Minah) ; Gliciphila albifrons incerta, Mat. 

 (Eastern White-fronted Honey-eater) ; C. melanops chandleri, 

 Mat. (Tawny-crowned Honey-eater) — the latter for the last 

 few weeks has been singing or whistling freely at Blackwood. 

 Mr. A. M. Lea exhibited a so-called hermaphrodite butterfly, 

 Delias my sis, from North Queensland, its right side having 

 the typical markings of a male, and its left side those of a 

 female; normal specimens were shown for comparison. Mr. 

 A. G. Edqtjist showed a beetle, the abdomen of which was 

 merely an empty skin. It had refused to feed, and had soon 

 died. Mr. F. R. Zietz exhibited a complete set of Aus- 

 tralian Falcons, viz., Falco longipen-nis (Little Falcon), F. 

 hypoleucus (Grey Falcon), Rhynochodon peregrinus (Black- 

 cheeked Falcon), and Noto falco subniger (Black Falcon). 

 Mr. E. R. Waite showed a plate of baleen (whalebone) from 

 the blue whale in the South Australian Museum; also the 

 jaw of a small-toothed whale. Mr. W. J. Kimber showed a 

 fish (Pegasus) from Port Lincoln, and various fossil shellr 

 from Port Willunga and Troubridge for identification. The 

 President showed a volume of newspaper cuttings (one of a
