[Plates XLIII.-XLVIL] 



r OR the opportunity of describing the following species of Ostracoda I am indebted to 

 Mr. G. M. Thomson of Dunedin, New Zealand, and to Dr. Meinert and Dr. H. J. Hansen 

 of the Museum of Zoology, Copenhagen. Mr. Thomson's specimens are the result of his 

 own labours in the pursuit of natural history at Dunedin, Brighton, and other places 

 in New Zealand ; those sent to me from Copenhagen belong to the museum of that 

 city, and were dredged in Lyttelton Harbour and Akaroa Harbour by Mr. H. Suter. 

 One very interesting species (Eupathistoma nutans) is from an altogether different 

 geographical area, having been taken in the Bay of Bengal ; for specimens of this 

 species I have to thank my friend Mr. I. C, Thompson, F.L.S., of Liverpool. 



Though, except in the case of Eupathistoma, there is nothing very strikingly new in 

 the morphology of the species here noticed, there are many points of interest as showing 

 deviations from the usual types of structure ; for example, the setose armature of the 

 first pair of antennae in Trachyleberis scabrocuneata, the peculiar hairy cushions covering 

 the valves of Sarsiella, the adventitious concretionary nodules found on the limbs of 

 Philomedes sculpta, and the shell-glands and ducts of Philomedes flexilis.
