NEW DIATOMS. 
By Prof. H. L. Smith, LL.D. 
The following new Diatoms are described by Professor H. L. 
Smith in the first number of the “ American Quarterly Micro- 
scopical Journal.” 
Homaeocladia capitata. H. L. 8. 
Frond membranaceous, umbellately branched ; branches elon- 
gated, and with corymbose capitate apex. Frustules linear, valves 
lanceolate, with acute and very slightly constricted apices; frus- 
tules densely packed, but not in series, or fascicles ; marginal 
punctas faint, 35 in *001. Length of frustule, *0008 in. ; breadth, 
*0002 in. Frond, P5" to 2". 
Black Rock, California. 
Meridion intermedium. H. L. S. 
Frustules sessile, cuneate, margins nearly smooth, valves with 
very faint pervious costa? in f. v., which are scarcely discernible in s.v., 
cuneate, rounded at the larger extremity. Length *00166 to *003.
