NEW DIATOMS.

ate, the other angles being without them. Cellules irregularly 
hexagonal. Margins striate ; connecting membrane finely punctate. 
Distance between the angles *059 mm. St. Bartholomew. 
New Forms found in a Barbadoes Gathering. 
25. Nitzschia GrafFei. Grun. MS. — Valves broad, with cuneate 
and rounded ends, almost parallel sides, slightly constricted at 
centre. Striae strong, 10 in. -10 mm., moniliform. Marginal 
puncta 5 in. *01 mm. L. -127-*14 mm. 
This form occurs in a gathering from Samoa and Port Jackson. 
(I have also found it in gatherings from the following localities : — 
Jamaica, Bahia and Pisagua. — F. K.) 
26. Bid&ulphia membranacea. Cl. — Valve elliptic, with rounded 
ends. F. V. quadrangular. Valve very large and membranaceus. 
The markings consist of very small cellules, arranged in lines cross- 
ing each other in three directions ; the lines are about 8 in. -01 mm., 
parallel on the middle of the valve, but somewhat radiant near the 
ends. The connecting membrane is covered by elongated puncta, 
arranged in lines somewhat coarser than those on the valve. L. 26. 
B. -085 mm. I have also found it in a gathering from Honolulu. 
(? a variety of B. balena. — F. K.) 
‘27. Actinocyclus ? tenuissimus. Cl. — Valve circular, with a row 
of marginal puncta. Marginal nodule distinct. Sculpture very 
delicate, granules arranged in lines, radiating from the centre. 
Diam. -04--08 mm. 
(Prof. Cleve refers Amphiprora? complexa to Castracane’s genus 
Amphitrite ; this form, however, does not belong to either genus, 
but is a true Palmeria. See “ Grevillea,” Vol. iii., p. 39. — F. K.) 
CALIFORNIAN SPHiERLE. 
By Charles B. Plowright. 
The following enumeration of Sphgeriaceous fungi is the result 
of several parcels of specimens, collected in California by my 
friend, Dr. H. W. Haikness. The majority were obtained by this 
gentleman and Mr. J. P. Moor upon the Sierra Nevada Mountains. 
Many of the species occurred at a considerable elevation above the 
sea level — 4,500 to 5,000 feet. Some very interesting species occur 
upon the celebrated “big trees” (Sequoia gig antea') in the Yose- 
mite Valley, while others equally novel were found upon Sequoia 
sempervirens. Amongst the species new to science the more 
striking are Sphoeria megalocarpa — a plant with very large perithecia 
— Sovdaria calijornica , and Gnomonia alni. Several of the more 
common European species occur in apparant abundance, while the 
growth of Sordaria bombardioides indicates that our less common 
species are not confined to this hemisphere.
