SPOLIA ZEYLANICA. 
while including in his long list of synonyms Alpheus avarus , 
De Haan, expressly distinguishes that species from the homony¬ 
mous Fabrician species. That Miers gave the preference to 
Audouin’s name over the earlier one by Say is obviously due 
to his error in dating Audouin’s “ Explication ” in the year 1809. 
That date may apply to Savigny’s unnamed figure, but the name 
was not given by Audouin till 1825, and was evidently unknown 
to Desmarest when he published his “ Considerations generates 
sur les Crustaces ” in that year. The synonymy given by Miers 
is criticized by Coutiere in his valuable treatise on the Alpheidce 
(p. 35), with the result that, apart from detailed description, the 
term Alpheus edivardsii (or its equivalent here adopted) becomes 
rather the designation of a group than the name of a species.

Other references are easy to find under those which deal with 
the family. The typical species Tanais cavolinii , Milne-Edwards, 
under the name Tanais tomentosus , Kroyer, is figured with 
admirable detail by Sarsin the Crustacea of Norway, vol. II., pi. 5. 
According to Dollfus, the date of the Precis d’Entomologie is 1828, 
not 1829 as I have supposed in “Willey’s Zoological Results.”
