Fiji: Island of Viti-Levu. 



We had only a few hours for collecting in Suva, and no 

 promising collecting ground was found in the neighbourhood of 

 the town. In the circumstances, it is surprising that as many as 

 twenty species of Bdelloids were distinguished, though several of 

 them could not be identified. 



List of Species Collected. 



Philodina brevipes Murray. Rotifer longirostris (Janson). 



ureta brycei (Weber). Habrotrocha longiceps (Murray). 



P. humerosa (Murray). H. angusticoUis (Murray). 



Callidina habita Bryce. H. constricta (Duj.). 



C. quadricomifera (Milne). H. nodosa sp.n. 



C. pacifica sp.n. Adineta vaga (Davis). 



C. papillosa (Thomp.). A. longicornis Murray. 

 C. muUispinosa (Thomp.) 



Notes on the Species. 



Pleuretra brycei (Weber). 



No drawing was made of the Fijian form, but it is noted that 

 there was a second dorsal row of four spines. The number of 

 lateral spines is not recorded. 



Callidina quadricomifera (Milne). 



Variety. — Very large (700//, long), trunk thick-skinned, 

 strongly stippled; teeth very thick. I only find the variety 

 possessing all of these characters in warm climates. 



Callidina papillosa (Thomp.) ? 



Variety. — Small, warts few, second trunk segment laterally 

 prominent. It approaches C. canadensis, but is smaller. 



Callidina muUispinosa (Thomp.). Plate XV. figs. Qa, 6b. 



Variety. — Short-spined, spines few except on the foot. On 

 first trunk-segment one lateral spicule, and a broad process, den- 

 tate at the end ; on second trunk-segment three short spines at 

 each side ; on central trunk no spicules except at the posterior 

 angles ; spines numerous on foot ; teeth 2. 



Resembling an Indian variety ; remarkable for the reduction of 

 spines on the central trunk, and the broad dentate processes on 

 the first trunk-segment. 



Callidina pacified sp. n. Plate XIV. figs. 3a-3c. 



Specific Characters. — Small, pale brown. Corona large, wider 

 than trunk, sulcus wide, antenna very short. Trunk normally
