Mr. H. Goss exhibited, for Mr. G. Bryant, a variety of the 

 larva of Trichiura crat(Frji. 



Mr. C. G. Barrett exhibited a specimen of Plusia moneta, 

 Fabr., a species new to Britain, taken at Beading by Mr. W. 

 Holland in July last. It was stated that the first specimen of this 

 species captured in England had been taken at Dover last June, 

 and is now in the collection of Mr. Sydney Webb, of that town. 

 Mr. Kirby said that Mynheer Snellen had reported this species 

 as being unusually common in Holland a few years ago. 



Mr. "W. Dannatt exhibited a variety of Papilio hectorides 

 from Paraguay. Mr. Osbert Salvin said he believed he had 

 seen this form before. 



Mr. C. J. Gahan exhibited a curious little larva-like 

 creature, found by Mr. A. P. Green in a rapid mountain 

 stream in Ceylon, and observed that there was some doubt as 

 to its true position in the animal kingdom. It was suggested 

 that it might possibly be an insect larva, and he was desirous 

 of eliciting information on this point. He could find no 

 account of any insect larva with a similar structure. It was 

 made up of six distinct segments, each of which bore a single 

 pair of laterally directed processes or unjointed appendages 

 coming off from the ventral side of the body a little below the 

 margin of the hard dorsal shield. Near the inner base of 

 each of these processes was a bundle of five club-shaped, 

 apparently branchial, filaments. Each segment had on the 

 middle of the under side a comparatively large sucker. The 

 anterior segment was furnished with a pair of two-jointed 

 autennal structures, in addition to a few stout bristles. 



Mr. Hampson supplemented these remarks by stating that 

 just behind the mouth, which was placed not far from the an- 

 terior margin on the under side, was a pair of broad flattened 

 jaws with rasp-like teeth, and that there was nothing that re- 

 sembled the mandibles of an insect. The appendages, which 

 were towards the sides and unjointed, were, he said, very 

 suggestive of the parapodia of certain chfetopod worms ; but 

 that all the known polych^etous worms were marine. 



Mr. Gahan agreed with these remarks, and said that the 

 animal seemed to have very much the characters of a poly- 

 chjetous worm. Lord Walsingham and Mr. M'Lacblan
