morphosis, and have active larvae and pupae, similar to the imago. 

 He also announced his belief that those insects which undergo a 

 complete metamorphosis, — as, for instance, the Lepidoptera, — are in- 

 capable of reproducing lost parts. To this very imperfect and par- 

 tial view of a most important subject, — a view so little in accordance 

 with the simple, uniform, and beautiful laws by which nature inva- 

 riably works, — I could not, as your President, afford my assent ; but 

 expressed my decided belief that a reproduction of lost parts may 

 take place in every Order of Insects, and throughout the whole of 

 the Articulata. Unwilling, however, that either opinion should go 

 forth to the world as that of the Entomological Society of London, 

 or of its President, or of its Secretary, unsupported by facts, I availed 

 myself of the earliest opportunity during the past summer of putting 

 these opinions to the test of actual experiment. Several series of 

 experiments were made on Vanessa Urticce and Vanessa Id with 

 complete success, and the results of these experiments, the perfect 

 insects, with their diminutive and newly-formed limbs, were exhi- 

 bited to the Society at our last October meeting. Some of these 

 specimens are now deposited in the cabinets of the British Museum, 

 and others in the Hunterian Museum of the Royal College of Sur- 

 geons; and the details of the inquiries have been published else- 

 where ; so that this physiological question may now be regarded as 

 completely settled. Experiments similar to my own were also made 

 about the same time by one of our best physiologists, H. D. S. Good- 

 sir, Esq., on the Crustacea. An interesting account of them was 

 given by Mr. Goodsir to this Society when my own specimens of 

 Lepidoptera were exhibited ; and it was gratifying to find, that al- 

 though some of the details of experiments on these two Classes of 

 Articulata differed slightly, the great principles in both were pre- 

 cisely the same. — From the Anniversary Address delivered at the

Description of a new species of Solarium. By R. B. Hinds, Esq., R.N.

 dis, superioribus longitrorsumplicatis, ared mediand pallidd, strigis 

 latis obliquis fuscis pictd ; ad peripheriam carinatd, supra ared 

 angustd planulatd maculis fuscis quadratis articulatd ; ad basin

The only specimen which is known to us is about the size of S. 

 formosum, and is therefore materially smaller than the finer speci- 

 mens of S. perspectivum or S. trochleare. The character of its orna- 

 tion is however so very distinct from either of these, that it would 

 mislead to push the comparison further. The species is perhaps rather 

 thinner and lighter than usual, the inferior whorls and base are some-
