 To '^ Hijperoche Kroeyeri, C. Bovallius," the synonyms are Metoecus medusarum, Kr0yer, 1838; 

 Hyperia mcrlusarum (O. Fabr.). Spence Bate, 1862; Metoecus medusarum (0. Fabr.), 

 A. Boeck, 1870; Tauria medusarum (0. Fabr.), A. Eoeck, 1872; " Hyperia Kroeyeri, 

 C. Bovallius," 1885. Thus Bate's Hyperia medusarum is cited for two genera.

A short account is given of Amphipods obtained on the coast or by dredging "entre la pointe de 

 Penmarch et I'embouchure de la Loire," an estent of about 100 marine miles. "La baie 

 du Croisic " was specially examined, a locality prolific in forms in proportion to the varied 

 nature of the ground which its waters cover. Elasmopus latipes, Boeck, was found by M. 

 Chevreux to be a commensal of Maia squinado, together with Isxa montagui, M.-Edwards. 

 Twenty other species, he says, are found more or less often on this crab. The total number 

 of known species obtained in the region examined amounted to 115, to which are to be 

 added three new forms, briefly described under the names Ptilocheirus tricrisfafus, 

 Microprofopus longimanus, Miovdeuiopius armatus. The last of these appears to come 

 very near to Stimpsonia chelifera, Sp. Bate ; see Ann. and Mag. Nat. Hist., ser. 5, vol. i. 

 pi. v., 1878. 



Incidentally " Stenothoe mnnoculoides Mont., Atrjlus Swammerdamii Milne-Edwards, Amathilla 

 Sahini Leach " are recorded from the coast of Algeria.

Notes sur les Amphipodes des Cotes de France. (Extrait des Froces-verbaux 



des seances de la Societe Zoologique de France, t. XL seance du 28 decembre 1886.) 



Fuller descriptions are here given by M. Chevreu.x of Ptilocheirus tncristatus, n. s., Micro- 

 protopus longimanus, n. s., and Mierodeiitopus armatus, n. s., from the south-west of 

 Brittany. M. de Guerne gives a list of thirty species of Amphipods from the north of 

 France, but he notes that the Podocerus falcatus, Montagu, and the Janassa variegaia, 

 Leach, which he includes in the number mentioned, are regarded by Nebeski as the male 

 and female of a single species. In my opinion the Amphithoe podoeeroides, Rathke, and 

 Amphitho'e riihricata, Montagu, are also a single species, though some specimens are green 

 and others red. Probably also the .=:pecies named in the list Podoceropsis rimapalmata, 

 Sp. Bate, and Podoceropsis excavata, Sp. Bate, are identical.
