Notes on Xostoehiuae. By Ilirain .\. Cuttinf^, A. M.,

 Cabinet, Luncnburgh, Vermont. 



Oil the 14th of St^ptembcr 1872. while looking for 

 dendrites on the schist rock in Newbury, in company 

 with Dr. J. M. Currier, we found the little pools of 

 water on the side of the r;iilrt)ad clo^cl}- filled with 

 alga:, which, upon examination, proved to be Nosto- 

 chine.e. The)- were round bodies resembling grapes. 

 in the main, though many were joined in shapeless 

 masses. They were from the size of a pin head to 

 one inch or more in diameter. In color they were 

 all shades of green. 



The j^hycoma or general mass of the plant was en- 

 closed by a pellicle or skin-like envelope, determinate, 

 clobose, but of various forms, gelatinous, soft, elastic, 

 containing, as shown under the micrcscope, simple 

 curved and entangled moniliform colorless or green- 

 ish filaments, composed of cells which appeared jolid.
