scope I then used. I have since found it in abundance in some 

 still water at Wood Green.

It is almost impossible to mount this beautiful larva in such a 

 way as to give any idea of its appearance when alive. In its 

 living state, it is one of the most curious and interesting of aquatic 

 larvae, and is so transparent that were it not from its dark-coloured 

 glands it would be very difficult indeed to find. Dr. Carrington 

 gives a full account of it, amply illustrated in Science Gossip, Vol. 

 4, p. 78, etc.

This object should have been mounted in glycerine.

I have been fortunate in finding the beautiful " Skeleton 

 larva," Coretiwa plumicornis, at Wood Green. A gentleman 

 exhibited at the Quekett, in 1874, a specimen of this larva 

 mounted in the act of changing to the pupa. Lardner says the 

 larvae are very scarce, and must not be fed in captivity if it is 

 desired to keep them in the early and more beautiful stage ; but 

 my experience does not confirm this, and even a plentiful supply 

 of Daphnia, etc., did not appear to accelerate the transformation, 

 which, in fact, occurred very seldom in my "aquarium" — i.e., a 

 bottle of water. I kept some all the winter, and they thrived and 

 grew considerably. The plan recommended by Rymer Jones 

 for mounting — viz., plain water and closing with gold-size, 

 answers admirably. I have one mounted nearly a year, which 

 looks almost like life. I think the larva very large for so small a 

 gnat.

Dermaleichus passimiis.— The greatly developed third pair of 

 legs, and the rudimentary condition of the fourth pair, afford an 

 illustration of the general law, that excess of development in one 

 portion of an organism is accompanied by arrested development 

 in the neighbouring parts.
