Family DAVAINEIDAE. 

 Subfamily Davaineinae. 



Raillietina Fuhrmann, 1920. 



Subgenus paeoniella Fuhrmann, 1920. 



Eaii-lietina (PARONiELiiA) BLANCHARDi (Parona, 1898). 

 Davainea blanchardi Parona, 1898, p. 2, pi. i, figs. 1--8. 



This species occurred together with Chitinolepis mjohergi 

 in Rattus sahanus at Mt. Duht. The two forms are of much 

 the same size and at the first glance not easy to separate. 

 Complete specimens, however, can be distinguished by the 

 great difference in the shape of the posterior segments, which 

 in R. hlanchardi ultimately become longer than broad. R 

 hlanchardi was originally recorded from Mas siporanus and 

 M. rajah. 



Ransoml\ Fuhrmann, 1920. 



Raillietina (Ranscmia) insignis (Steudener, 1877). 



Taenia insignis Steudener, 1877, p. 298, pi. xxxi, figs. 1--7. 

 Davainea insignis Blanchardi, 1891, p. 434, fig. 12. 



This species occiuTed in considerable numbers in Dncula 

 badia at Mt. Murnd. Tt has been recorded from Glohicera 

 [Carpophaga'] oceanica, to which the present host is closely 

 related. There are also in the British Museum specimens 

 which probably belong to it from Treron delandii, from East 

 Africa. 



Raillietina (Ransomia) calyptomenae sp. n. 



Host : Calyptomena whiteheadi (a Broadbill). Locality : 

 Mt. Murud. 



The strobila (in the preserved material) attains a length of 

 6--10 cm., and a maximum width of 0.9--1.15 mm. The 

 diameter of the scolex is 0.17--0.25 mm. The suckers measure 

 0.055—0.08 mm. in diameter, and are armed with minute 

 spines. The rostellum has a diameter of 0.1—0.125 mm., 

 and is armed with very numerous hooks, arranged in two 

 irregularly alternating rows and measuring about 0.008 mm.
