for the determination of most of the species of Phyllopods, Copepods, 

 and Ostracods, a laborious piece of work which will be useful to many. 



Ostracods from Australia.* — Frederick Chapman reports on a 

 collection of Ostracods made by the F. I. S. 'Endeavour ' from the east 

 coast of Tasmania and off Cape Wiles, South Australia. He deals with 

 f( >rty-rive species and two varieties, nearly all new to that area of the 

 Southern Ocean. There are some new species : Macroeypris gracilis, 

 Xestoleberis davidiana, Gytheropteroji dannevigi, and G.fimbriatum, and 

 some new varieties. Several of the deep-water species, such as 

 Argillwcia affinis and Bythocythere retiolata, have hitherto been recorded 

 only from Funafuti in the South Pacific. A number of very rave forms 

 occur, such as Eucythere declivis, a North Atlantic species, only once 

 recorded from the southern hemisphere.

Parasitic Oligochaete from Gill-chamber of Land Crabs.t — H. A. 

 Bay lis has described Enchytrseus carcinophilus, which occurs frequently 

 and in considerable numbers in the gill-chamber of Gecarcinus lagostoma 

 from South Trinidad. He describes another species, E. parasiticus 

 sp. n., from Gecarcinus quadratus from Clarion Island (Pacific). 

 Syrphid larvae were found in Gardisoma hirtipes from the Admiralty 

 Islands, and in Gecarcoidea lalandii from Christmas Island : but these 

 may have entered accidentally, and possibly after the death of the 

 crabs. It is not easy to see how the Oligochsete worms subsist, for they 

 are without jaws. Perhaps they eat mucus. 



Polychastes collected by the ' Hirondelle ' and ' Princess Alice. ; J 

 Pierre Fauvel gives in a large and stately memoir an account of 

 the non-pelagic Polychfctes collected on the various voyages of the 

 'Hirondelle' and the ' Princess Alice.' He deals with no fewer than 

 288 species, in 158 genera, and twenty-eight families. Five genera and 

 twenty-one species are new to science. Another new genus, Phalacro- 

 stemma, was described by Marenzeller before Fauvel took up the work. 

 Most of the specimens were collected in the areas off Spitzbergen, 

 Norway, the Bay of Biscay, the Azores, the Canaries, and Cape Yerd. 

 Seventy-five species were found below 1,000 metres, fifteen below 

 2,< mo, * eighteen between 4,000 and 5,000, three between 3,000 and 

 4,000 (a depth at which few trials were made). The species from the 

 greatest depths include few distinctive forms ; most are also littoral 

 and common. The new genera are Pseudohalosydna near Halosydna, 

 Palmyreuphrosyne near Euphrosyne, Paralacydonia near Lacydonia, 

 Pseudocapitella near Gapitella, and Spirodiscus, a remarkable Serpulid. 

 The author is to be congratulated on the completion of a gigantic piece 

 of work.
