In conclusion, the following comments may prove suggestive:

Out of fifty-five vials of the Chinese cestodes from Charadriiform birds, fifteen have not been determined definitely, owing to the poorly preserved condition and to insufficient material for detailed study, such as Pe 510, Pe 517, Pe 526, Pe 529, Pe 552 b, Pe 588, Pe 593, Pe 1466, Pe 735 c, Pe 1431 d, Pe 760, Pe 144 b, Pe 151, Pe 848 and Pe 841 d.

In this paper, seven species are described as new, namely, Amoebotaenia fuhrmanni, A. pekinensis, Monopylidium guiarti, Choanotaenia joyeuxi, Haplo-paraxis sinenis, Fuhrmanniella clerci, and Gyrocoelia fausti.

The present study indicates, to a certain extent, that the Chinese fauna of the avian cestodes is more or less related to that of the Ural, Australia, Egypt and Europe.

Pe 848 is an interesting tapeworm recorded from the liver of Totanus calidris. Owing to the poor preservation, the strobilae can not be examined, but its incomplete rostellar hooks, larger 0·0234 mm., and smaller 0·0216 mm. shown in Fig. 54, are characteristic.
