Habitat ad Teria Ghat, 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 Helix Tollini, Albers, recorded in a former Num- 

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

 lius 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 gigaSy 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 Germination of the Lycopodiese. 

 By Dr. A. de Bary*. 



The complete failure of all attempts hitherto made to obtain 

 the germination of the Lycopodiaceae proper, such as Lycopodium, 

 Psilotum, and Tmesipteris, 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. Hofmeister. 



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 SelagineUa, 

 which were long confounded with them under the same generic 

 denomination. On the other hand, however, the Lycopodieae 

 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 Pteridese of Griesbach, 

 while Selaginella, presenting at the same time two kinds of
