Mr. R. South read a paper on British snake-like reptiles. 



The author having briefly referred to Professor Huxley's 

 division of the Zoological sub-kingdom Vertebrata into 

 three primary sections, viz. : Ichthyopsida, Sauropsida, and 

 Mammalia, made some remarks on the apparently in- 

 congruous grouping together of reptiles and birds in the 

 section Sauropsida. He then proceeded to deal with the 

 class Reptilia, and observed that of the four orders in this 

 class represented by living forms in the present day, only 

 two, viz. : the Ophidia and Lacertilia had representatives 

 in Britain. 



The three British Ophidians, and one snake-like Lacer- 

 tilian were then discussed at some length.

Mr. T. R. Billups exhibited three species of Ichneu- 

 monidae, new to Britain : — 



Bassus bizonarius, Gr. (PI. 1., Fig. 13), taken in his garden 

 at Peckham, May, 1885. 



Erromenus {Trichocalymma, Foerst.) plebejum, Wolds 

 (PL 1, fig. 10), taken at Dulwich, June nth, 1885. 



Perilissus triangularis, Bridgm. (PI. 1, fig. 9). The male 

 was taken in his garden at Peckham, May, 1885, and the female 

 at Croxted Lane, Dulwich, May, 1885. He stated that he 

 was indebted to his friend, Mr. J. B. Bridgman for the identi- 

 fication of these three new species, which he has fully described 

 in a paper read before the Entomological Society of London, 

 July 7th, 1886, and printed in full in the Society's Transactions 

 for 1886. 



Mr. Dobson exhibited wasps' nests of the genus Odynerus, 

 found under a doorway in the New Forest.
