borne at the end of long robust branches ; antheridia diclinous, : 
stout, dark ; oospores globular from 5 to 20 in the oogontum, — 
usually however about 10 in number, 20u in diameter. Zoo-— 
sporangia produced later, filamentous, the zoospores escaping by — 
a narrow beak-like opening at the apex. Chlamydospores in ~ 
large numbers, mostly developed on stout lateral branches. J 
Beyond telling us that these two species were found at Bandon, — 
Mr. Swan has not indicated their habitat, although he mentions | 
‘that there is probably no open water in Ireland without — 
Saprolegniaceae. One of the distinctive generic characters of” 
Leptolegnia is the occurrence of but one oosphere in the — 
oogonium. Mr. Swan has placed his new species, which numbers — 
many oosplieres in Leptolegnia, without explaining his grounds | 
for doing so, or without emending the genus, which would be | 
necessary in order to include L. bandoniensis. Mr. Swan con- 
siders that the unusual production of chlamydospores is probably — 
due to the conditions of culture. 
Achlya apiculata De Bary, Bot. Zeit., 1888, p. 635. 
Hyphe stout 40-60 in diameter; sporangia terminal; oogonia — 
single, at the end of short, often bent branchlets 12m thick, — 
which rise in a crowded manner from the main hyphz, elongate- — 
ovate, ending in a sharp point, varying in size from 65 to 75p 
broad and 105 in length, smooth with few oospores ; antheridia — 
always present, often more than one to each oogonium, borne on 
slender branches which rise from the main hyphz near to the 
oogonial branch; oospores mostly 3-4, globose 35-50 in diameter, 
smooth.

Effused rosy-white ; sterile hyphe creeping, continuous filiform, 
with here and there short fertile branches, umbellately branched 
at the tips ; conidia acrogenous, globose, minutely muricate, rose —
