A specimen of this gastrophrynid from Kuching, Sarawak, Borneo 

 (U.S.N.M. No. 53650), 21 mm. long, bore numerous Cepedeas with 

 rather small, spherical, or somewhat elongated nuclei and ciUa of 

 medium length in widely separated lines. They seem distinct.

 N.M. No. 36315), 67 mm. long, well infected, the female (U.S.N.M.

 only, the smaller animal with no opaUnids. 



This Cepedea has long cilia in lines unusuaUy far apart. Some m- 

 dividuals have nearly all nuclei elongated and large, probably ap-
