504 NOTES AND EXHIBITS. 



Mr. E. Cheel exhibited a collection of seeds of various species of Coral 

 Trees, Erythrina spp. as follows: — Erythrina indica Lam., collected at Lautoka, 

 Fiji, in July, 1918. The specimens agree with those in the National Herbarium 

 from the Philippine Is., but ai'e quite distinct from those plants common in 

 Public Parks jind gardens in the neighbourhood of Sydney and the Illawarra 

 District. The latter appear to be E. coralludendron Linn., and have hitiierto 

 been confused with E. indica. So far as he could ascertain no pods or seeds 

 have been collected from trees of the latter species grown in New South Wales. 

 In the National Herbarium there are a few seeds, received from the late F. 

 M. Bailey from Brisbane labelled E. indica, which are identical with specimens 

 of E. coraUodendron. received from Professor C. F. Baker of Panama College, 

 collected in Nicaragua and distributed under No. 123. The seeds of E. coraUo- 

 dendron are of a bright red colour and somewhat resemble those of E. caffra 

 Thunb. which is cultivated in the Botanic Gardens, but are larger. The flowers 

 are very different. Specimens of a white flowering form of E. indica from Fiji 

 were also exhibited. 



Mr. A. N. Burns exhibited larvae, pupae and perfect insects of Paralucia 

 aurifer Blanch. The larvae feed at night on the leaves of the blackthorn 

 (Bursaria) and hide during the day at the base of the plant; they were found 

 at Narrabeen during September and November and as usual were attended by 

 ants. He also exhibited larva, jtupae and perfect insects of Protialmenus 

 Uthochroa Waterhouse, collected by Mr. .1. D. 0. Wilson at Reynella, S. Aust., 

 the food plant being Acacia pycnantha. 



Miss M. I. Collins exhibited specimens of Clianthus Dampieri showing 

 colour variations from Broken Hill, and germinating seeds of Crinum sp. 



Professor David exhibited a specimen of fossil wood, bored by Teredo, 

 from the base of the Rolling Downs Formation of Queensland, and a specimen 

 and microsections of limestone from the same Formation at the Maranoa River 

 containing abundant microzoa (Radiolaria. Tintiiinus. etc.) and Diatoms; also 

 samples of petrol absorbed from the natural gas at the Roma Bore, Queensland, 

 depth 3700 feet, and paraffin wax from the Ruthven Bore, 4100 feet, Central 

 Western Queensland.
