This anomalous and very peculiar species was at first mistaken for a new generic type, bui so far as 
can be determined from the material, its antheridia arc not different from those of other meinln rsof the 
genus, and the multiplication of the cells of the secondary axis or fertile branch, and the ootncideiioe of die 
latter with the primary receptacle, which is in no way distinguished from it, are points of secondary im- 
portance. It resembles M. St. Helena more closely than perhaps any other species, the peculiar append- 
ages being strikingly similar. The long and usually nearly opaque axis is very like thai of Khackom ij<< * 
The peculiar staphylinid hosts on which it occurs are sparingly clothed with long stout hairs or seta\ ainong 
which the parasite is often distinguished with difficulty. Specimens growing on the jaws, or other por- 
tions of the host where they are exposed to unfavorable conditions, often product ccoodary fertile branch- 
lets, as in fig. 40, but this condition is exceptional; the normal form, a- it occurs on tin abdomen or in 
other favorable situations, being similar to that represented in fig. 39, which is the type form. The sixk 
however, varies considerably in the number of cells which compose it and in the depth of its suffusions. 
The hosts are tropical insects living under bark.

Receptacle consisting of a basal and subbasal cell, the latter producing terminally ■ rterilc u]>]*ndage 
and laterally a fertile branch (abnormally more than one) the axis of which is coinc ideal with thai of the 
receptacle, from which it is not distinguished, and consists of a series of superpo I cell the terminal 
one bearing an antheridium and a stalked perithecium; the rest bearing antheridia or pan I sterile ap- 
pendages from their upper inner angles. The antheridia compound, home on paired stalk-cells, and 
consisting of very numerous antheridial cells arranged in sul.horizontal, or oblique tiers; the Berk sepa- 
rated externally by two superposed sterile cells, and opening into a common cavity from which the 
antherozoids are discharged by a common outlet between four appendicular cells which terminate tb 
antheridium and arise from the two primary terminal cells of the antheridium, is in Umwwmycrs. 
The only material from which it is possible to form an approximately accurate idea oi the structur 
of the antheridium in this genus is that of E. Papuans, the hosts of which were preserved ,n alcohol. 
Although the form is very small, careful examination with a r \ oil immersion render* its general eel -arrange- 
ment sufficiently clear, notwithstanding the fact that from the irregularity of its outline and of the cells 
composing it, the different appearances that may be obtained from different points of view are very confus- 
ing. In the lateral view, fig. 15, which is practically the same on both sid- . and is the one atoost ".van- 
ably seen in preparations where the individuals lie flat, the stalk-cell appears to be, as was stated m the 
original description, single. It can be determined, however, by careful focusing or when a van interior 
or posterior in relation to the fertile branch is obtained, that the stalk like I hat of Hnnn,™,^.* uo

of a pair, as in M onoicomyces , two series of rows of antheridial cells are produced, one on ether «de 1 hen
