174 A. E. Lechmere. 
were not nearly so numerous as with the former species (p. 170, figs. 
11 and 12). 
Laterally formed sporocysts. A few cases were found where a 
sporocyst arose as a lateral branch below the one already discharged. 
The case figured (p. 175, fig. 1) shows this condition and a new 
sporocyst growing up within the wall of the first-formed sporocyst, 
thus apparently combining the Achlya and Saprolegnia- type of 
formation. 
The A planes type. In several hanging drop cultures of a few 
days’ growth, cases occurred in which the spores had failed to dis¬ 
charge and had germinated in situ (p. 175, fig. 2). 
Dictyosporocyst. In many cases of the gemmae developing 
directly into sporocysts with long tubular processes, the majority of 
spores failed to discharge, so the second motile stage takes place 
within the sporocyst and after the escape of the zoospores the 
empty cases remain in the sporocyst (p. 175, fig. 3). 
Comparison of the Species. 
From the general appearance of this species in the cultures 
and the facility with which it produces gemmae, it showed a very 
close resemblance to the species described in the previous paper. 
The size and shape of the gemmae and the methods of germination 
of the resting sporocyst type are identical in two cases. The general 
life-history, with the exception of the formation of oocysts and 
antherocysts is also identical. 
The resemblance is further carried out by the occurrence of 
certain identical variations of the normal sporocyst, such as the 
Achlya- type of branching of the sporocyst, the Aplanes-t ype of 
sporocyst with the spores germinating in situ, the formation of 
Dictyosporocysts, and, lastly, the formation of multiple sporocysts, 
or chains of gemmse. 
The chief points of difference are the abundant formation of 
oocysts and antherocysts, and also parthenogenetic oocysts in the 
present species, and the comparative rarity of the occurrence of the 
multiple sporocysts or chain-gemmae which were produced in great 
abundance in the last species. 
The following characters are common to the present “ Species 
1.” and that referred to as “a species of Saprolegnia ” in the 
previous paper:—
