Measur&ments of a good-sized iridwidual. — Length of body 0.34 

 mm.; width of body, 0.051 mm.; diameter of nuclei 0.0026 mm.. 

 0.0035 (mean), some nuclei 0.0045 mm. by 0.0035 mm.; diameter of 

 endospherule 0.0017 mm. (a few endospherules are 0.0017 mm. by 

 0.0008 mm. as if divided) ; cilia line interval, anterior 0.0022 mm., pos- 

 terior 0.0034 mm. 



This Cepeda is somewhat like C. multiformis., but is more spindle- 

 shaped and has smaller nuclei which are spherical, or nearly so. 

 Compare here C. Tnadagascariensis., whose longer individuals show 

 an approach to C. longa. 



CEPEDEA DOLICHOSOMA, new species (flg. 136, p. 167). 



Type. — United States National Museum Cat. No. 16530. 



Host. — Bufo haematiticus Cope, five infections, one from Costa 

 Rica and four from Nicaragua, August 7, 1885; J. F. Bransford, 

 collector; all of the latter, including the type infection, are from a 

 jar of United States National Museum specimens numbered 14181. 

 The host furnishing the type infection is 38 mm. long. 



MeasureTnents of a large individual. — Length of body 0.848 mm. ; 

 width of body 0.03 mm. ; diameter of average nucleus 0.0053 mm. 



This is another multiform species. The longest, slenderest indi- 

 viduals, except for their spherical nuclei, would be assigned to the 

 species C. longa, but other individuals much resemble some of the 

 forms of C. multiformis. It seems to be an intermediate species. 

 more longa-like than C. Tnultiformls. 



CEPEDEA LONGA (Bezzenberger). 



Opalina longa Bezzenbekger (1904). 



A specimen of this form has been deposited with the United States 

 National Museum as Cat. No. 16519. 



Host. — Rana limnocharis Wiegmann, reported by Bezzenberger 

 from "Asia." I have had three infections from Japan and one from 

 Formosa. The example of this species which I have deposited with 

 the United States National Museum as No. 16519 is from United 

 States National Museum specimen of this frog No. 36502, 41 mm. 

 long, from Giilan, Formosa, September, 1906 ; T. Tada, collector. 



Measurements: A, after Bezzenberger; B, of an ordinary indi- 

 vidual, from one of my infections —
