basilar joints at least are united to the anterior half of the labium, almost 

 hiding it, and the terminal joint is so small that its existence is doubtful ; this 

 bears a minute seta. The antennae are four jointed, the terminal joint bears a 

 stiff bristle. Beside the last joint and in front of it is a rouoded body which is 

 either a separate joint or a process of the third joint, which of the two I have not 

 satisfied myself. Behind each antenna is a row of three blackish eye-spots, 

 each emarginate in front, centrally behind these is a fourth, and at a little 

 distance above this a fifth ; these two last are blackish circles broadest in front. 

 Kear these are several bristles. The body consists of 12 segments ; they are so 

 transparent that much of the internal anatomy can be seen, some of it being 

 obscured by regularly disposed masses of white fat. There are thr3e pairs of 

 four-jointed legs, the last joint being a slender brownish claw. Each segment 

 has laterally a stifif-looking hair with two or three smaller ones. The 13th (last) 

 segment has similarly two larger hairs and several smaller ones. There is a 

 slight projection on the ventral surface of this segment, hardly pronounced 

 enough to be dignified by the name of anal tubercle or proleg. There are ten 

 pairs of spiracles, the first is situated below the line of the others at the anterior 

 border of the third segment, the second at the anterior border of the fourth 

 segment. This one is smaller than any of the others, but I have satisfied myself 

 that it is really an aperture and not merely an approach of air tubes to the 

 surface. The others are situated more and more towards the middle of their 

 respective segments, so that the last four or five may be said to be so placed. I 

 shall not add any remarks here on the fact of this larva possessing ten pairs of 

 spiracles, as I hope to make some observations on this and some similar facts 

 in a separate note. 



By this time the dinner-hour had arrived. Sufficient provision had not 

 been made for the number of members who attended, since so many cama 

 without giving any notice of their intention to do so, and some gentlemen 

 were unfortunately obliged to leave in consequence. 



After dinner the President brought forward the distressed state in which 

 the family of Professor llichael Sars, of Christiania, had been left by his 

 unexpected demise. A plate was handed round the table, and £3 7s. was 

 collected, which the president undertook to forward. 



Three glass bowls from the fish-hatching apparatus of J. F. Symonds, 

 Esq., Broomy-hiU, contained the ova and young fry of the salmon, the Great 

 Lake trout, and the common trout. They created great interest, and the circu- 

 lation through their transparent vessels was afterwards well shown by Mr. 

 With's microscope. 



The President then read his retiring address, and, on the proposition of 

 Sir George H. Cornewall, Bart., and Arthur Armitage, Esq., received the thanks 

 of the Club for his exertions in its interest as president during the past year, 

 amidst much applause.
