They most resemble C. formosae in shape and size and in the dimen- 

 sions of the nuclei, but the dividing nuclei are much more elongated, 

 as they are in C. celebensis. It seems to be another case of inter- 

 grading species. 



cepedea pmlippensis 



Figure 72 



Host: Bufo guadri'porcatus Boulenger, from Pulo Sugi, Rhio Archi- 

 pelago, south of western Sumatra, 2 specimens (U. S. N. M. Nos' 

 30986 and 30987), both infected. 



FlQUHE 72.— Cepedea philippemis: a and b, X 146; c, X 673. 



Measurements, in microns: Body (a) 229 by 50, (6) 128 by 29; 

 (c) width of body 30. Other measurements from c: Nucleus 5.4 by 

 4.3, daughter nucleus 7.3 by 4.3, dividing nucleus 8 by 5; length of 

 cilia 9.9; cilia line interval 2.5. 



CEPEDEA LUZONENSIS, new species 



Figure 73 



Type: U.S.N.M. No. 22639. 



Host: Rana luzonensis Boulenger, one specimen (U.S.N.M. No. 

 38047), 60 mm. long, from Benquet Province, Philippiue Islands, 

 collected July 1, 1907, and annotated "Heights in the Oaks." 



This frog bore a generally slender Cepedea whose forms of body, 

 forms and sizes of nuclei and ciliation do not agree with any other 

 species described. The general impression from the appearance of 

 an infection is distinct, and this is one of the most reliable indications 

 even when indefinable. 



Measurements, in microns: Body (a) 240 by 60, (6) 180 by 55, 

 (c) 60 by 31, (d) width of body 36. Other measurements from d: 

 Nuclei 4, 4.9 by 4, dividing nuclei 5.9 by 4, length of cilia 8.9, interval 

 between lines of cilia 2.7. The number of nucleoli is probably 4.
