13. Alona pulchella, King. 



I am somewhat in doubt whether this be a true Alona, as 

 the sculpture of the shell would seem somewhat different, the 

 stria? running rather obliquely, in which respect it appears 

 rather to agree with the genus Alonella. 



14. Alona diaphana, King. 

 Gen. Alonella. See above. 



15. Alona Karua, King. 

 Gen. Alonella. See above. 



16. Alona mascula, King. 

 This form is perhaps the male of Alona Bairdii, King. 



17. Dunhevedia crassa, King. 



See above. 



18. Dunhevedia podagra, King. 

 Undoubtedly congeneric with the last species, and apparently 

 specifically distinct.
