 genus Parnassius, having special relation to the development, functions, and 

 structure of the horny pouch found in the females of this genus. He de- 

 scribed the habits, distribution, and variations of twenty- three species which 

 he recognized in the genus ; and illustrated his remarks by the exhibition of 

 a very complete collection of specimens and drawings. The paper was sup- 

 plemented by Prof. Howes' s remarks on his examination of the anatomy of 

 the Parnassius apollo, and by Mr. Thomson's notes on the habits of the in- 

 sects as bred in the Society's Gardens in 1885. — Mr. Oldfield Thomas,

25th January. — Dr. J. Spencer Cobbold read a paper on Strongylus 

 Axel and its affinities. This diminutive Maw-worm, obtained from the sto- 

 mach of a Donkey, possesses interest, in as much as its structural characters 

 closely correspond with those of the entozoon [Strongylus Douglasii, Cobb.) 

 infesting the Ostriches proventriculus. It also shows affinity with the grouse 

 Strongyle [S. pergracilis) and with the stomach worm [S, contortus) of Lambs ; 

 while its peculiarities throw light upon other questions of morphology, 

 especially its relations to the singular Maw-worm [Simondsia pa?-adoxa, Cobb.) 

 of the Hog. — J. Murie.
