Habitat ad Teria Glnit, cum prsecedente. 



I have named this little species from its habit, observed by 

 Mr. Theobald, of springing several inches from the ground, like 

 the little Cape He/i.v Tal/ini, Albers, recorded in a former Num- 

 ber of this Journal on the authority of Mr. E. L. Layard. V. Sa- 

 Hhs also occurs near Darjiling, where Mr. W. T. Blanford has 

 found it sparingly, in company with another new species. 



Mr. Theobald met with my large species, Vitrina giyas, at 

 Cherra, on the mountains above Teria Ghat ; it was not com- 

 mon. On the limestone at the same place, a solid variety of the 

 little Western Himalayan shell, H. plicidens, B., was common.

XXII. — On the Gei'inination of the Lycopodieae. 

 By Dr. A. de Bary*. 



The complete failure of all attempts hitherto made to obtain 

 the germination of the Lycopodiacese proper, such as Lycupodium, 

 Psilutum, and Tniesipteris, leaves an important and very unsatis- 

 factory gap in the history of the development of the Vascular 

 Cryptogams, otherwise so well made out, thanks especially to 

 the happy investigations of Dr. W. Ilofmeister. 



By their mode of growth, their general organization, and 

 especially by the position and development of their sporanges, 

 the Lycopodiese proper are closely connected with the Selaginella, 

 which were long confounded with them under the same generic 

 denomination. On the other hand, however, the Lycopodiese 

 proper resembled the Ferns and Equisetacese in possessing only 

 one kind of reproductive body. Now, as the spore of the Ferns 

 and that of the Equisetacese both give birth to a prothallium 

 furnished with sexual organs, these two families of Cryptogamia 

 constitute a particular natural class, the Pteridefe of Griesbach, 

 while Selaginella, presenting at the same time two kinds of
