lined "end-gut," and great reduction of the nervous system, is proposed for 

 the reception of an undescribed copepod, so far found only in the genital 

 ridges of the Enteropneust, Ptychodera australis Hill, still known only from 

 the type-locality, a few miles north of Port Jackson. — Description and Life- 

 History of a new Species of Nannophlebia [Neuroptera: OdonataJ. By R. 

 J. Tillyard, M. A., F.E.S. — The larva and imago were discovered on the 

 Bellinger River, N.S.W. , in November last. The discovery is important, 

 because no other larva belonging to Ris's Group i. , of the Libellulinae 

 has so far been found. As this group contains all the supposedly archaic 

 remnants of the subfamily, it was expected that the larva would throw some 

 light on the phylogeny of the groups of the Libellulinae in general. The 

 general theory of the descent of the Libellulinae from a Corduline stem 

 is discussed in the light of the new facts, but the author is unwilling to ac- 

 cept the idea propounded by Dr. Ris, that the Libelluline anal loop is se- 

 condarily developed from a narrow-winged ancestry similar to Group i. — 

 Notes on Australian Lycaenidae. Part v. By G. A. Waterhouse, B.Sc, 

 B.E., F.E.S. — The synonymy of a number of species, referable to the genera, 

 Danis, Miletus , Ccmdalides , Naoaduba, Theclinesthes , Pseudalmenus , and 

 Ialmenus, whose identification by Australian entomologists has hitherto been 

 difficult, is cleared up. — On some Trematode Parasites of Marsupials, and 

 of a Monotreme. By S. J. Johnston, B.A., D.Sc. — Two species of Har- 

 mostomum, parasites from the marsupial "cat" Dasyurus viverrinus, and the 

 bandicoot, Perameles obesula, respectively, are described as new. These 

 worms are very closely related to Harmostomum opisthotrias Lutz, parasitic 

 in the South American marsupial, Dìdelpìiys aurita ; and constitute some in- 

 teresting circumstantial evidence of the phylogenetic relationship of the South 

 American and Australian Marsupials. A new genus, Mehlisia } is instituted 

 for the reception of two species, one a parasite in the intestine of Dasyurus 

 viverrinus, and the other in the intestine of the Platypus. These two species 

 are looked upon as representing a subfamily Mehlisiinae, intermediate in 

 position between the Fasciolinae, parasitic in higher mammals, and the 

 Psilostominae, parasitic in birds and reptiles.
