OPALINID CILIATE INFUSORIANS METCALF 



OPAUNA species (?) 



555 



In a specimen of Eana jerboa Gunther (U.S.N.M. No. 44013) from 

 Tjiburrum, Java, Mount Gede, at 6,400 feet altitude, one specimen 

 only of a large Opalina was found. It was not preserved. 



OPALINA species (?) 



Two examples of Rana verrucosa Gravenhorst, 32 and 36 mm. 

 long, collected in September 1914 and sent by the Madras Museum 

 from Parambikulam, Cochin State, southern India, showed a few 

 remnants of a large Opalina, too poorly preserved for study. 



"OPALINA TERMITIS" de Mello

Hosts: Two termites — Leucotermes indicola from India and Calop- 

 termes militaris (?) from Daman, Portuguese India. 



This form is somewhat Uke Opalina, yet one can but doubt its 

 belonging to the Opalinidae. I have found only de Mello 's reference 



Figure 124.— "Opalina teTuiitis" de Mello. (After de Mello.) 



to the form in the Report of the Third Entomological Meeting at 

 Pusa, India, and this and the accompanying figures (copied in our 

 fig. 124) are insuflacient for critical determination. Especially figure 

 124, c, a stage in what must, from the course of the lines of cilia, be 

 a transverse division, is unhke any appearance hitherto f()und in a 

 dividing Opalina. One cannot tell whether the animal is flat or 

 spheroidal. Another major difficulty in classing this as an Opalina 

 is the great difference between the aquatic reproductive habits of 

 the Anura and the terrestrial reproduction of the termites. The 

 life history of the opalinids includes encystment of minute mdividuals 

 their passing into pools of water where they Ue upon the bottom until 

 they are ingested by browsing, vegetarian, aquatic larvae of Anura 

 in whose recta they hatch from the cysts and develop into male and
