I would here express my great indebtedness to Professor 

 Haswell for placing at my disposal any literature which he 

 possessed, and for his kind encouragement in every way. 



I would also take this opportunity of expressing my thanks to 

 Dr. Hill for his kindness in placing the specimens at my disposal. 



Methods. — Corrosive sublimate proved an excellent fixative 

 with these specimens, and I find that Castle advises the use of 

 that reagent in fixing Glossiphonids. Specimens fixed in Zenker's 

 fluid show a certain amount of distortion as regards the cellular 

 elements. Entire specimens cleared in cedar oil gave me much 

 help preliminarily in the study of the gross anatomy of the 

 digestive system. 



Castle* recommends iron-hrematoxylin as the best stain for 

 sections; and I found sections so stained to outclass those stained 

 with other reagents. The strongly developed musculature offers 

 good material for a counter stain with eosin. 



The specimens were imbedded in paraffin by the benzole method 

 after having been cleared in cedar oil, and good results were thus 

 obtained. 



The genus Glossiphonia (Clepsine) is well represented as regards 

 species in North America and Europe, where much work and 

 attention have been given to them by Whitman, Castle, Apathy, 

 Grube, Mueller, Oka and others. 



In 1900 Dendy and Olliver described what was regarded as a 

 biannulate species of Glossip7wnia from New Zealand, but later 

 it was found to be a species of Microbdella Moore. 



The species of Glossiphonia described in this paper constitute, 

 I believe, the first record of the genus from Australia. Lately I 

 have obtained other species from Tasmania and the mainland, 

 so that the species is a really very widely distributed form. 



Glossiphonia is characterised among the Glossiphonid Rhyn- 

 chobdellidse by the triannulate nature of the somite and broad 

 flat body which is rolled into a ball when disturbed after the
