XVIII.— Some Parasitic Worms from Sa- 

 rawak. By H. A. Baylis, m.a., d.sc. 



(Published by permission of the Trustees of the British 

 Museum.) 



The following report deals with a collection of parasitic 

 Nematodes and Cestodes made rectr.tlv in Sarawak by Dr. 

 Eric Mjoberg, late Curator of the Sarawak Museum, Kuching. 

 and kindly submitted by him to the writer for determination. 



The material included eleven species of Nematoda and nine 

 of Cestoda. Of the Nematodes, one species was represented 

 only by a headless fragment, and was indeterminable. One 

 of the Cestodes, a species of RaiJlietina from a Barbet, 

 Cyanops puJcJierrima. was also in rather poor and fragmentary 

 condition, and has not been more precisely determined. Of 

 the remainder, at least one Nematode and three Cestodes are 

 believed to be new species, and one of the Cestodes seems to 

 represent a new genus of considerable interest. Several of the 

 other species represented in the collection are very little-known 

 forms, and advantage has been taken of the opportunity to 

 supplement the existing descriptions of Subulura perarmata, 

 Streptopharagus pigmentatus and Oesophagostomum ovatum. 



Some of the hosts are rare or little-known animals, and it is 

 of particular interest to have obtained material from the 

 Bornean Mydaus, a badger-like animal which is related to M. 

 javanensis from Java and Sumatra. 



Syntypes of the new species will be deposited in the British 

 Museum (Natural History) and in the Sarawak Museum, 

 Kuching. I also refer in the following to some odd finds from 

 other parts of Sarawak.
