CoBBOLDiNA nom. nov. 

 * for CohholcHa Leiper 1910, preocc. 



In my memoir on the " Entozoa of the Hippopotamus " pub- 

 lished in the Proceedings of the Zoological Society for 1910, 

 at page 235, I described and figured a new genus CohholcHa 

 having as type Cohholdia vivipara, sp. n. 



Mr. Hassall and Dr. Schouteden have kindlj^ drawn my 

 attention to the fact that Cohholdia has been used already for 

 a genus of Insects and is therefore not available. I propose 

 to replace Cohholdia Leiper 1910, by the new generic name 

 Cohboldina.
