Prof. Von Siebold distinguishes three entirely distinct and very complicated 
systems of salivary glands ; two of which, a lower and an upper, are situated 
in the head, and the third in the anterior part of the thorax, the latter 
having been erroneously regarded by Fischer as a lung. Each of them has 
separate excretory ducts, and is distinguished by a specifically different form 
and organization of the vesicules secreting the saliva. Each consists of a 
right and left glandular mass, with right and left excretory ducts. 
" For the detailed account of their minute structure we must refer to the 
paper itself, and the plate accompanying it, but we must add that this extra- 
ordinary development of the salivary organs has been observed by Prof. 
Von Siebold in the workers only. The queen possesses only a rudiment of 
the lower cephalic system in the form of tlie two orifices of its ducts, 
•whilst the ducts themselves with the glands are absent ; and the two other 
systems are much less developed than in the workers. In the drones not 
even the orifices of the lower cephalic system could be found." (Bieneu- 
zeitung, 1872, No. 23). 
Mr. Meldola, at the request of Mr. J. Jenner Weir, referred to the chemical 
composition of malt-sugar as compared with sugar in honey. It was stated 
that malt-sugar had the same composition as glucose; while honey, in 
addition to glucose, contained cane-sugar or saccharose. Mr. Weir remarked 
that it was an interesting fact that this chemical transformation of malt- 
sugar into a sugar containing a different percentage of carbon should take 
place in the economy of the honey-bee. 
Mr. Smith read ' Descriptions of Aculeate Hymenoptera of Japan, col- 
lected by Mr. Geo. Lewis, at Nagasaki and Hiogo. Of seventy-three species, 
forty -nine were previously unknown. He remarked that the distinctness of 
his Apis nigrociucta from A. mellifica, recently questioned by Dr. 
Gerstiicker, had been abundantly confirmed by the discovery of a queen of 
A. nisrocincta.
