of the walls of the (non-sterile) cysts; however many may be 

 crushed by the dog's teeth, numerous others escape to perpetuate 

 the species. 



Mr. G. A. Waterhouse exhibited specimens of Etiplcea corinna 

 Macleay, from Sydney, Brisbane, Cairns, Cape York, and Port 

 Darwin. These demonstrated that this species is not subject to 

 geographical variation in Australia. At Cape York, occasional 

 aberrations occur, in which the white spots are reduced in size; 

 more rarely some of the white spots are absent. Miskin described 

 two such aberrations((j9) ^nid^r the name EupJcea euclus; but 

 the present exhibit not only showed examples even more divergent 

 from typical corinna than Miskin's specimens, but also inter- 

 grades between E. corinna and E. euchis. In a note upon the 

 exhibit Mr. Waterhouse said : " Dr. K. Jordan has kindly 

 examined, for me, Felder's types of this genus in the Tring 

 Museum. He has written to me that Euphfa anyasi Felder, is 

 identical with E. corinna; the type of E. angasi shows the single 

 brand in the ^. The second of Felder's species recorded from 

 Australia is E. hwini, which is without a brand in the ^. Dr. 

 Joi'dan considers that the locality given is incorrect, and with 

 this view I quite concur; no Euplasa known from Australia agrees 

 with the description of E. lewini." E. hoisduvali Lucas, is pro- 

 bably another synonym. 



Mr. E. Cheel exhibited the following interesting species of
