6. Succinea approximans^ Shuttle worth. 



7. Helicina fasciata, Lamarck. 



8. Helicina Gwppyi^ Pease. 



In my list of terrestrial Mollusca from Dominica I acciden- 

 tal! j omitted Helicina G-oldfussi^ Bottger (Jahrbuch deutsch. 

 mal. Gesell. 1887, vol. xiv. p. 103, pi. iv. fig. 10). 



This will raise the total number of species known to inhabit 

 the island to thirty-four. No freshwater shells have hitherto 

 been recorded from this locality. Mr. Guppy presented to 

 the Museum some specimens of iVen<ma^Mnc<?</a^a, Lamarck, 

 which he had himself collected, and specimens of this species 

 have also just been received from Mr. Ramage. This well- 

 marked form occurs in many of the Greater and Lesser An- 

 tilles and has also been recorded from Mexico. 



BIBLIOGEAPHICAL NOTICES. 



Catalog der Conchylien- Sammlung . Von Fk. Paetel. 

 8vo. Berlin, 1887-1888. 



The first volume of this work is now complete, and a few remarks 

 upon it may therefore not be out of j)lace. In the preface we are 

 informed that the ' Catalogue ' wiU consist of three parts : the first, 

 that now before us, to contain lists of the Cephalopoda, Pteropoda, 

 and marine Gastropoda, the second the land and freshwater * Gas- 

 tropoda, and the third the Acephala and Brachiopoda. 



The scope of the work is to give a list, not only of the species 

 and varieties contained in Herr Paetel's own collection with their 

 habitats, but also the names of all other recent species which have 

 been described, and such synonyms as were known to the Author. 

 A reference is also added to those species which are desiderata in 

 his collection. 



The great value of a Catalogue of this kind lies in its completeness 

 and accuracy. Is it or is it not reliable ? Unfortunately the two 

 requisite qualities mentioned appear to be wanting in an eminent 

 degree in the present work. One or two illustrations taken at random 

 will suffice. On page 1 at least half a dozen synonyms and species 

 are omitted in the list of Argonauta, and under Suborder I. Octopoda 

 no list appears of the 70 or 80 known species of Octopus, and in 



* The Melaniidse, Ampullariidfe, and Viviparidae, the largest freshwater 

 groups, are given in vol. i.
