The gathering from the river Scheldt (for which I am in- 

 debted to Mr. E. C. Davison) exhibits a curious mixture of 

 marine and freshwater species, the former, however, being 

 chiefly such as exhibit a decided preference for littoral, estua- 

 rine, or sub-brackish habitats, e.g. Cytliere castanea^Cytheridea 

 littoralis ^Loxoconclia ellijitica^ Xestoleberis aurantia^ andCytlie- 

 rideis siihulata. The uniformly good preservation of the shells 

 would, nevertheless, lead to the supposition that all the species 

 were really living in company at the place where they were 

 found. Two of the new species included in this list {Cyjn-i- 

 dopsis ohesa and Gytheridea cornea) will be described and 

 figured from British specimens in a future communication. It 

 may be noted that the specimens here refeiTed to Cyther-ura 

 ,'iimilis, though agreeing perfectly in shape Avith an outline 

 drawing obligingly sent to me by Herr G. O. Sars, differ 

 strikingly from his description in their surface-ornament, being 

 distinctly punctate, and bearing also several small, distant, 

 circular papillas. The drawing of C. similis given in my 

 ' Monograph of the Recent British Ostracoda ' is faulty, and 

 has the posterior beak too much produced. 



The lists of species from the Mediterranean exhibit an inter- 

 mixture of British species similar to what has been noticed on 

 a previous occasion. Those marked with an asterisk have 

 been described in a French periodical, ' Les Fonds de la Mer ;' 

 the remainder of those to wliich my name is afhxed will be 

 found in the ' Transactions of the Zoological Society,' vol. v., 

 in the ' Monograph of the British Ostracoda/ or in previous 

 papers of the present series. The specimens which I have 

 doubtfully referred to Loxoconclia tamarindus are rather larger 

 than tliat species as it usually occurs on the British coast, 

 measuring about one-fortietli of an Inch in length : they arc 

 also soinewliat more ventricosc, and sliglitly diHferent in out-
