type. lie describes Allolobophora Lonnbergi sp. n., named after the 
collector, All. caliginosa Sav., All. Beddardi sp. n., Pontodrilus ? bermu- 
densis Bedd., Pontodrilus sp., Geodrilus Eiseni sp. n., Perichseta indica 
Horst. The presence of the three species of Allolobophora points to the 
affinity of this region with the region characterized by Lumbricidse 
(Siberia, Europe, North America); All. Beddardi is nearly related to 
All. parva Eisen of New England ; Geodrilus is distinctively North 
American. The presence of Pontodrilus seems at first sight strange, but 
this genus is littoral, not terrestrial, therefore not limited by the same 
conditions as the terrestrial forms ; and as for Perichseta indica it is 
probably carried by man. There are none of the characteristic West 
Indian forms. 
New Oligochaeta from Illinois.* — Mr. F. Smith publishes a pre- 
liminary account of the larger Oligochaetes collected during the past 
summer. Diplocardia riparia is the name given to a new species which 
is closely compared with D. communis , and the differences between them 
are pointed out in a table. Sparganophilus Eiseni sp. n. is very abundant 
in the mud of the Illinois river. It agrees in many points with 
S. tamesis, lately described by Dr. Benham, but has a sufficient number 
of distinctive marks to justify its being regarded as a distinct species. 
Funnels and Terminal Vesicles of Hirudinea.j — Dr. A. Graf has a 
preliminary note on this subject ; as against Bolsius he agrees in most 
points with Bourne. He finds that in Clepsine the funnel resembles 
closely that of Nephelis. The connection between the nephridial gland 
and the funnel takes place within the ventral sinus. The funnel is sur- 
rounded by chloragogenous cells in the interior of the ventral sinus. In 
Nephelis the terminal part of the nephridial gland always goes close to 
the wall of the ampulla, in which the funnel lies. Opposite the terminal 
portion of the gland there is always an opening in the wall of the 
ampulla, and this opening always corresponds to the bottom part of the 
funnel. With Aulostomum the author was less successful than with 
the other genera, but he found that the funnels lie in sinuous vesicles 
dorsal from the testis, and at the side of the intestine. These funnels 
are closely surrounded by an enormous quantity of chloragogenous cells 
which seem to form a sort of gland with intracellular $ucts. The 
funnel is many-lobed ; the ciliated cells greatly surpass in number the 
ciliated funnel-cells of Nephelis. With regard to the terminal vesicles, 
the author finds that in Hirudo the terminal vesicle is spacious and lined 
with richly ciliated epithelium. The duct connecting the vesicle with 
the exterior (terminal duct) enlarges into a secondary vesicle. This 
terminal duct is surrounded by circular muscle-cells, the number of 
which is increased at the opening of the vesicle into the duct, and near 
the communication of the duct with the exterior. 
New Discedrilid.t — Under the name of Pterodrilus , Mr. J. P. Moore 
describes an American parasitic leech. It is remarkable for the presence 
on certain of the post-cephalic somites of paired dorsal appendages 
chiefly developed from the muscular layers of the body. These dorsal
