REPORT ON THE AMPHIPODA. 43 



ApL stands for " Bomares Katur-historie af H. von Aphelen." 



On p. 280 Mliller says, with a reference to No. 2358, " Arhsegiarsoah augmentativum ex 

 Arksegiak nom. Caucri gener." On p. vii, abbreviations, &o., are thus explained, " Species 

 asterisco* notata; in scriptis perillustris equitis a Linne frastra quajruntur, signo f 

 impressEe a civibus, signo + a me, detecta indicantur. Nomina vcrnacula, quibus 

 nulla litera majuscula anteponitur Danis et Norvegis comniunia sunt, reliqua D. Banos, 

 N. Norvegos, I. Islandos, L. Lappones, Gr. Groenlandos significant." 



Of these species No. 2355 is generally accepted as Hyperia medusarum, Miiller; No. 2356 

 remains obscure; No. 2357 rejieats Strom's description from the Acta Havn., 1765, 

 of what is probably Orchestia (jammardlus ; No. 2358 in like manner refers to Strom's species 

 of 1770, now become Amathilla Iwmari, Fabr. ; No. 2359 is synonymous with Caprella 

 linearis (Linn.), Bate; No. 2360 is now called Proto ventricosa, Miiller; No. 2362 

 answers to Corophium volutator, Pall.; No. 2366 includes probably two or three species, 

 such as Ganimarus lociista and Gammarus ]ndex. No. 2353, Cancer g(l)acialis, is probably 

 not an Amphipod ; No. 2354 may be a Caprella.

In the Explicatio Tabularum, under Tab. xli., is given the reference, "I>. d. Cancek sedentarius. 

 Pag. 95, n. 59." Figure " d " is a recognisable figure of Phronima sedenfaria free ; figure 

 " D " represents it in its semitransparent case. For the description of this species, see note 

 on Forskal, 1775.

Here the genus Scorpio is transferred to Class V., the Unogata. The other five genera of the 

 Agonata are retained in the same order as in his earlier work. The account of the genus 

 Gammarus is as follows : — " Gammarus. Cancer Linn. GeoflP. Oniscus Pallas. Os mandibulis 

 palpisque absque maxillis. Palpi sex, inaequales, filiformes ; anterioribus quatuor porrectis,
