no necessary connection. The worm (Gastrodiscus Sonsinonis) appeared to 
be an aberrant Amphistome furnished with a singular ventral disc, whose 
concavity was lined with about 200 small suckers, which when viewed with 
a pocket lens presented a tesselated appearance. In this respect its nearest 
approach was a worm infesting a genus of spiny-finned fishes (Cataphractus) 
belonging to the Triglide. According to information recently received from 
Prof. Leuckart, anatomical investigation throws doubt on its Amphistomoid 
affinities. 
The Secretary read, for the author, a paper “ On the Papilionide of 
South Australia,” by Mr.J.G. Otto Tepper. The specimens were captured 
chiefly in the counties Adelaide, Light, Sturt, and Ferguson, York's 
Peninsula. The scarcity of butterflies in the province, thirty species in 
all, as compared with other countries, is somewhat remarkable, and the 
sombreness of their coloration is also notable. Brick-red, various shades of 
brown, white, and black are the most frequent tints among the larger 
species, these seeming to agree with the surroundings of their habitat; for 
the author mentions having. at times had difficulty in recognising insects 
when settled, so closely did they approximate in colour to the ground. 
Mr. Tepper expresses his belief that the small numbers of the Lepidoptera 
in this part of Australia is due to the great dryness of the atmosphere, for 
the frequency of occurrence in any given locality seems to bear a proportion 
to the presence or absence of surface-water. During the N.W. winds they 
collect in groups in shady places, and they are then weak and lethargic, 
many being found dead. Brief notes on habits and locality are appended 
to descriptions of most of the species found by the author, and the following 
names are provisionally given to forms which he has been unable to 
identify :—Hesperilla trimaculata, H. quadrimaculata, H. bifasciata, H. 
atro-alba, H. lutea, and H. gracilis —J. Munir.

The Secretary read a report on the additions that had been made to the 
Society’s Menagerie during the months of June, July, August, September, 
and October, 1880, and called attention to some of the more remarkable 
accessions which had been made during that period, viz.:—A male Leonine 
Monkey, Macacus leoninus, from Arracan, received in exchange, June 14th, 
from the Zoological Gardens of Calcutta. A Tufted Umbre, Scopus wmbretta, 
from Africa, purchased June 26th, being the first example of this peculiar 
African form that has been received. A pair of Ocellated Turkeys, Meleagris 
ocellata, from Yucatan, presented by Mr. W. K. Sibeth, July 20th. Two
