 PBOTOOPALINA XAMACHANA, new species 



Figure 33 



Type: U.S.N.M. No. 22625. 



Host: Eleutherodadylus luteolus (Gosse), a leptodactylid, from 

 Jamaica, West Indies. Two preserved specimens of this host were 

 examined, both collected by W. Harris, August 18, 1905. One showed 



no infection; the other, 29 mm. 

 long, was abundantly infected. 

 Two elongated nuclei, often 

 dumbbell-shaped, with 4 nucleoli 

 in each end, are usually found. 

 The yellow hosts along with their 

 eggs were found by Harris in the 

 water in the cups at the bases of 

 Bromelia leaves growing as epi- 

 phytes on trees on Mount Di- 

 abolo. It is interesting that these 

 "aquatic" tadpoles in Bromelia 

 leaf cups are infected like other 

 aquatic tadpoles that Uve in 

 much larger pools. 



Measurements, in microns: 

 Body 90 by 40, 90 by 30, 52 by 

 14; nucleus (elUptical, in anaphase) 18.1 by 7.1, nucleus (dumbbell- 

 shaped, early telophase) 27 by 6.1; cilia length 10; ciha line interval 

 2 ; nucleoU 4. A few of the animals show a slight posterior point. The 

 character of the nuclei places this species in group V. 



PBOTOOPALINA XENOPODOS Metcalf 



I described this species from Xenopus calcaratus Buchholz and 

 Peters, from the Belgian Congo. Fantham describes what he regards 

 as the same species from X. laevis from Johannesburg, South Africa. 



Fantham gives measurements, in microns, as follows: Body length 

 82-144, width 14-27; one ciliate 156 long and 31 wide; tailed gamete 

 from tadpole 44.2 by 5.8. Nucleoli 4 (Fantham says 8 but shows 4 

 at each end of the dividing nucleus).
