Sarcosporidiai and the fish Psorospermice or Myxosporidicn. The 
Microsporidia of the Silk Moth, Attacus pernyi, are minutely described, 
as also those of an Orthopteron, Platycleis grisea.

Two new forms, figured and described, are found as parasites within 
the enteric canal of Phalangiida. A ctinocephalus jissidius , sp. n., has 
developed at the anterior extremity twelve pairs of cleft hooklets, be- 
tween each of which pairs is a simple spiniform process. In Stylorrhyn- 
chus caudatus the head-like anterior region is placed on a neck-like stalk, 
and has developed upon it twelve ridges or projections, which extend 
beyond the margin of the head, and then divide. At the opposite end a 
slender caudiform appendage is developed, which is not separated by a 
distinct septum from the body proper.

The Gregarine genus Stylorrhynchus, inhabiting Blaps , was found to 
produce spores, aggregated in the form of a rosary. The matured spores, 
being moistened with fluid from the intestine of the host, open along 
their convex border, and give birth to sporozoa, which creep out by 
movements of their anterior extremity. After prolonged observation, 
these sporozoa endeavour apparently to penetrate the subjacent surface, 
which, under normal conditions, would be represented by epithilium. 
An examination of the intestinal tissues of the Blaps reveals the pre- 
sence of Coccidia in every phase of development. The development of 
the Monocystis-form is produced by the division of the sporozoite into 
ptypMtM, T)w p/wmy mm (a wMa m % wp Ui tM 
or bead-like region of the Ulytorrhynehub. The development ot the 
spores of the gonus Klossia is likewise fully described.
