4(3 SUMMARY OF CURRENT RESEARCHES RELATING TO 
Queensland ; they belong to six species — four of Geoplana, and one of 
Bipalium and one of JRhynchodesmus ; only two are new to science, but 
of these Geoplana regina is a remarkably handsome worm. The widely 
spread Bipalium Kewense was, Prof. Spencer thinks, introduced by the 
agency of man to the locality (Gympie, Mary River) where he found it. 
Dr. Dendy thinks that the remarkable development of the head of 
Bipalium is a most marked and important character, and of great value 
for the purposes of classification ; for it has a certain normal shape, to 
which it constantly returns. 
Victorian Land Planarians.*— Dr. A. Dendy has a further descriptive 
paper on the land Planarians of Victoria, twenty-two species of which 
are now known ; it is probable that they may be found at all times of 
the year by diligent searching, but they are more abundant in spring 
and autumn than in the drought of summer or the excessive moisture of 
winter. The present memoir contains systematic observations on twenty 
species of Geoplana. 
Revision of Monostomida.f — Dr. G. Brandes does not agree with 
Dr. Monticelli in thinking that the Monostomida should be so defined 
as to include Didymozoon ; speaking generally, the Monostomidae are 
those digenetic Trematodes which have only one sucker, but it is to be 
understood that a truly Holostomid form like Hemistomum cordatum is to be 
regarded as a Monostomid. M. liguloideum is shown to be an Amphiline ; 
M. Squamula is a Bistomum ; M. echinostomum is a synonym of D. planicolle , 
and M. hystrix of D. endolobum. M. spirale is also a Distomid, while 
M. cochleariforme appears to be a Gastrostomum , and it is not possible to 
be certain about M. cornu . M. mutabile , M. flavum , M. arcuatum, M. 
Tringse, and M. ellipticum may be certainly regarded as good species, 
and the first four are allied to one another ; similarly M. verrucosum , 
M. alveatum , M. trigonocephalum, and M. Hippocrepis seem to form a 
group of allies. About twenty-four good species of the genus appear to 
have been described. 
Notes on Water-Vascular System of Mesostomidae4 — Dr. E. Sekera 
finds some exceptions to Graff’s generalization that the oral and water- 
vascular orifices are always combined in this family. In Mesostoma 
rostratum the double excretory branches open by two excretory pores 
below the genital orifice ; similar remarks may be made as to M. cyathus , 
M. hirudo , and M. Hallezianum. There are certain points of interest 
in Castrada , and in Bothrioplana , on which further information is 
promised. 
Rare Parasites of Man.§ — Prof. F. Zschokke has some notes on 
Tsenia ( Hymenolepis ) diminuta, which has been five times recorded from 
the human intestine. An example of Cysticercus cellulosee was found 
lying under the skin of a man thirty-nine years old. Another may be 
added to the three cases of the presence in Man of Bistomum lanceolatum ; 
twelve specimens were observed in a corpse in the Arabian Hospital at 
Alexandria.
