CONTRIBUTION TO OUR KNOWLEDGE OF 

 AUSTRALIAN HIKUDINEA. 



Part iii.

 THE Society in Zoology. 



(Plates xlv.-xlvi.) 



The present paper deals with two species of Glossiphonia 

 Johnson, 1816, (syn. Clepsine Savigny,1820), one of which is new 

 to science, the other a cosmopolitan form now recorded for the 

 first time from the Australian region; and also with a description 

 of our commonest and longest known aquatic Arhynchobdellid, 

 which I find is now to be known as Limnohdella australis in place 

 of Hirudo quinquestriata after taking into consideration the 

 generic characters, and giving preference to Bosisto's prior specific 

 name rather than to Schmarda's quinqibestriata. 



Since describing two species of Glossiphonia in these Proceed- 

 ings (1908, p. 320), and Dineta, gen.nov. (o;;. cit. p. 854), I have 

 been fortunate enough in collecting to obtain a number of aquatic 

 Hirudinea, the greater number of which belong to the genus 

 Glossijyhonia. 



I can here preliminarily also record the occurrence of Herpoh- 

 della (syn. N'ephelis), specimens of which I obtained in the vicinity 

 of Sydney, and in the Maitland District. 



I have met with specimens of Glossiphonia im a very large 

 number of places in the coastal district, including Fairfield, 

 Narara, Auburn, Oberon, Omega, Gerriftgong, and Maitland. In 

 some cases, as in creeks, they are found on floating weeds or 

 reeds; in the case of ponds or dams, one finds them frequentl}^, 

 in abundance, adhering to floating or submerged pieces of wood. 

 I have found that species of this genus are always associated with
