OPALINA ANNANDALI, new species 



Figure 100 



Host: Rana tigrina Daudin. 



Of two freshly preserved specimens of this frog collected by Pro- 

 fessor Annandale in the garden of the Indian Museum at Calcutta 

 one bore many Opalinas of an undescribed species. The very thin 

 posterior edge is indicated in the figures between two "x" marks. 

 The infection shows a few individuals with abruptly sharp posterior 

 points. Their irregular shapes are similar to those of 0. natalensis, 

 0. rotunda, and 0. zeylonica. 



Measurements, in microns: (a) Body 128 by 57, nuclei 3.1, 3.3, 

 3.8 by 2; (b) body 112 by 75, nuclei 3.5, 4 by 2.8. 



This species resembles the japonica group in shape, and in dimen- 

 sions of nuclei.

From Tillimanti, southern India, 2 uninfected frogs; from Rham- 

 nad, southern India, 2 frogs uninfected; from Bogawantalava, 

 Ceylon, altitude 4,000 feet, 5 frogs, 3 infected. Bezzenberger's 

 figure shows but one of a number of shapes. A posterior point may 

 or may not be present. Frequently it may be exaggerated into a 

 well-developed tail. Dividing or even fragmenting individuals (di-
