Land, Fresh- Water, and Marine Crustacea. 379 



specimens of an Idothea that appear to me to belong to this 

 species. 



After Porcellio pictus (p. 140), add 



The genus Metoponorthus, Budde-Lund, 1879, and the species 

 M. jpruinosus (Brandt). This Oniscoidan species has been 

 captured (in April this year) at Slateford, near Edinburgh, 

 by Mr William Evans, and is recorded by him in the Annals 

 of Scottish Natural History for July 1906, p. 187. 



Gammarus Dueheni, Lillj. (p. 163). 



To the localities for this species add : Brackish pools, 

 Luffness, near Aberlady, July 1906 (W. Evans). 



Genus Jassa, Leach (p. 170). 



The two species, Jassa falcata (Montagu) and Jassa 

 yusilla (G. 0. Sars), have been removed to the new genus 

 Bruzeliella, ISTorman. See Crustacea of Devon and Cornwcdl, 

 p. 92. 



Corophium grossipes, Linn^ (p. 172). 



This species, under the name of Cancer grossipes, was 

 described by Linne in 1767 in Sy sterna Naturae, vol. i. part 2, 

 p. 1055 ; but as Pallas had already, in 1766, described under 

 the name of Oniscus volutator, what appears to be the same 

 form (cf. Miscellanea Zoologica, p. 102, pi. xiv. fig. 20), the 

 name of the species should be Corophium volutator (Pallas), 

 with C. grossipes as a synonym. 



Protella phasma, Montagu (p. 174). 



Professor Mayer in his work on the " Caprellidae of the 

 Bay of Naples," Caprelliden des Golfes von Neapel, Nachtrag, 

 p. 19, refers this species to the new genus Pseudoprotella.
