the bee vanished. A long interval of patient watching ensued, when a second bee came 

 home, a similar movement of the toad followed, and the bee again vanished : but the 

 light of the lantern being this time thrown full upon him, he was distinctly observed 

 to swallow. The toad was caught and killed, and eight still living bees were taken 

 from his stomach. I attempt no explanation of the mode in which the toad attained 

 his station at the entrance of the hive, or what antidote he possessed against the poi- 

 son so likely to be conveyed by the stings of the bees ; all I can do is to vouch for the 

 veracity of my informant, which I do without any hesitation." 



Mr. Weir, in reply to an observation made as to the difficulty of a toad's climbing, 

 stated that he knew an instance in which a toad had climbed up an open door, and 

 seated himself on the top. 



2. Oniscus Armadillo. — " Finding this milleped extremely injurious to ferns and 

 Lycopodiums, I have paid some little attention to its habits, with a view to arresting 

 its increase. In pursuing this object, I have made a few observations that appear to 

 me of some interest. In the first place, the female is strictly viviparous, and the young 

 are perfectly developed while still in the ovary of the female : they are from sixteen to 

 twenty-two in number, and after birth attach themselves to the legs of their parent, 

 and are carried about by her. I found them first in this position ; afterwards I ob- 

 served the female in the act of parturition ; and, lastly, I killed several females which 

 appeared gravid, and found the young apparently ready for extrusion.* In the second 

 place I find that the young, although possessing perfectly developed organs of locomo- 

 tion, manducation, &c, have not the configuration of the adult : the second segment 

 (? cephalothorax) being proportionately larger, and bearing the eyes, which are situ- 

 ated near its exterior margin. Thirdly, the similarity of these minute millepeds 

 to the extinct trilobites, particularly to the genus Asaphus, is most striking, especially 

 in the figure of the enlarged second segment, and the position of the eyes, which are 

 elongate, linear, very distant, and have a reflexed external margin. The difference 

 between the infant and adult Oniscus Armadillo, and the similarity of the infant O. 

 Armadillo to a trilobite, would almost induce the conclusion that the trilobites were a 

 lower form of Isopod Crustacea, rather than allies of Limulus and cognate genera. 

 This similarity to a trilobite, is equally apparent whether the milleped be extended or 

 rolled into a ball." 



3. Typhlocyba Filicum. — "I beg to exhibit, under the provisional name of 

 Typhlocyba Filicum, a minute Hemipterous insect, which a good deal resembles the 

 Typhlocyba Ulmi of Germar, Walker, and other entomologists, but which seems to 

 me to be specifically distinct. The anterior wings are bright yellow to rather below 

 the middle, the apical portion transparent, irrorated with black ; the head is yellow- 

 green, with prominent black eyes ; the prothorax is also yellow-green ; the scutellum 

 is an equilateral triangle, and yellowish green ; the abdomen is intensely black, with 

 the extreme margin of each segment yellow, thus giving it a distinctly annulated 

 appearance. My object in desiring to attract the attention of the Society to this 

 little creature, is to point out the excessive injury which it commits in ferneries. 

 To ferns in a wild state it is highly injurious, often changing their delicate green
