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. Cythere castanea,Cytheridea 

 littoral 'is ^Loxoconcha ellijjtica, Xestoleberis aurantia 1 mi&Cythe- 

 rideis subidata. 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 (Cyprt- 

 dopsis obesa and Cytheridea cornea) will be described and 

 figured from British specimens in a future communication. It 

 may be noted that the specimens here referred to Cytherura 

 similis, though agreeing perfectly in shape with an outline 

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

 strikingly from his description in their surface-ornament, being 

 distinctly punctate, and. bearing also several small, distant, 

 circular papillae. 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 which my name is affixed 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 Loxoconcha tamarindus are rather larger 

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

 measuring about one-fortieth of an inch in length : they are 

 also somewhat more ventricose, and slightly different in out-
