A HISTORY OF DEVONSHIRE 



the Mysidacea have no proper branchiae to display. For a long time this order was mixed up with 

 the Squillidae under the common name of Stomapoda. Mr. Parfitt in 1870 no doubt intended to 

 accept this nomenclature, although he misprints the title as ' Stampoda.' In the preliminary report 

 on the feuna of Plymouth Sound in 1888 the word is adopted in its improved form ' Stomatopoda,' 

 but the Marine Biological Association having entrusted the list of Crustacea to Spence Bate, he not 

 only maintained the discarded union of the Squillidae with the Schizopoda, but mixed up with them 

 still a third order then known as the Cumacea, and threw in a Phyllosoma apparently just for the 

 fun of the thing. In these matters there are plenty of pitfalls even for the wary. The synonymy 

 of Praunus flexuoms will be some indication of this. It is a pretty little multitudinous species 

 which no collector fails to observe. How to choose its right name is the puzzle. The genus 

 Myiis was established by Latreille in 1802 for Cancer pedatus of O. Fabricius, with a suggestion 

 that Cancer oculatus of the same author was a nearly related species. This ill-defined genus was 

 subsequently made the recipient of many other species, which in turn have been redistributed 

 to several genera. In 18 13 Leach established the genus Praunus for P. flexuosus apart from 

 Mysis, and although he afterwards rejected the name flexuoius in favour of Mysh spinulosa, 

 that procedure was not in accord with modern views of propriety. Since Muller's flexuosus has 

 been by general consent removed from Mysis, it is obvious that it must now be restored to 

 Praunus. Even so we are not clear of our difficulties. For in the Plymouth catalogue of 1904 

 Mr. Beaumont writes as follows ; — 



' Macromysis flexuosa (Mtlller) and M. nigra .• F. Keeble and Gamble, Phil. Trans. Roy. Soc, 

 (Ser. B), vol. cxcvi, pp. 332, etc. 



'Together these two species include, but they do not respectively coincide with, the Macromysis 

 flexuosa and M. neglecta of Sars and of Norman. Both are known to occur in the Plymouth area, 

 but they have only been quite lately differentiated, and consequently their distribution has not yet 

 been fully determined. The evidence at present available points to the conclusion that M. flexuosa 

 is essentially an estuarine form, and M. nigra more strictly marine. This is in agreement with 

 the experience of Gamble. The Macromysis which swarms about the shores of the Tamar at 

 Saltash (especially in the summer months) appears to be exclusively M. flexuosa. In Plymouth 

 Sound M. nigra is the predominant form. . . .' ^ 



It should be mentioned that Schistomysis parkeri was described by Norman from specimens first 

 found at Starcross by Mr. C. Parker. 



On the synonymy of Dasymysis longicornis the reader must be referred to the elaborate 

 discussion by Messrs. Holt and Beaumont.^ They reject the earlier genus Acanthomysis of 

 Czerniavsky on the ground of misdescription. Whether the reason is adequate seems open to ques- 

 tion. Siriella rostrata (Gu^rin) has a right of priority over S. armata, if we believe Gu6rin's statement 

 that his figure of the species was published long before the description by Milne-Edwards.' 

 Gastrosaccus appears to have been used for a fossil crab some years before it was applied to an 

 existing schizopod. It must therefore give way to Acanthocaris, the, generic name applied by Sim 

 in 1872.
