472 PEOCEEDIKGS OF THE NATIONAL' MUSEUM vol. 87 



Dr. Stejneger, however, has expressed doubt of the leptodactylid 

 afiiiiities of Heleophryne, in spite of its resemblance, suggesting that 

 it may well be a ranid in a state of arrested development. Its parasite 

 throws no light upon this suggestion. 



I am unable to give illustrations of the Protoopalina from Heleo- 

 phryne, to which when found I gave the provisional name of ^'capensis, 

 new species." In some way, not understood, during my several 

 years of illness the material has disappeared. It was of such unique 

 interest that I separated it from the material of about 30 other species 

 still to be studied, and placed it so carefully away that with all my 

 searching it has not reappeared. Apparently moving my laboratory 

 and getting settled in a new place, when I was too iU to give it proper 

 attention, led to the disappearance of this especially prized material. 

 The provisional name must not be accepted without more adequate 

 description and the preservation of a type specimen. I gave it only 

 for convenience of reference. The fact of the infection of a specimen 

 of Heleophryne regis by a Protoopalina of the most primitive subgenus 

 is, however, definitely recorded. 



PBOTOOPALINA CAUDATA MICROHYLA Nie 



FiGUBE 25 



Host: Microhyla ornata Dumeril and Bibron, Indian Mus. No. 

 17287, sent by Professor Annandale; collected at Harnai, Ratnagiri 

 District (south of Bombay), among mountains. 



Measurements, in microns: Body, 147.7 by 43.3; nucleus, 14 by 8.5; 

 cilia length, 9.7. Apparently 6 (?) nucleoli. 



This form resembles P. caudata. Its posterior end is slightly pointed 

 in a few specimens. Its measurements are about as in P. c. dis- 

 coglossi. 



PROTOOPALINA DORSAUS (Raff) 



Figure 26 



Host: Limnodynastes dor satis (Gray). I have had one good in- 

 fection from a frog 54 mm. long (U.S.N.M. No. 64043) from Busselton, 

 Western Australia, collected by C. N. Hoy, June 8, 1920. 



Measurements, in microns: Body, 240 by 60, 100 by 68, 180 by 33; 

 nucleus, 25 by 8.9; ciha length, 9.8. Nucleoli, 4. 



My specimens belong apparently to Raff's species. They are 

 somewhat intermediate in appearance between P. caudata and P. 

 intestinalis. I am therefore placing dorsalis, along with P. peronii, 

 in group II with them.
