anterior; the femoral joint of the second pair of legs is not clavate in the linearis, and is 

 also quite straight." 



CapreUa linearis, after describing -which he says, " this appears to be the Caprella liiiearia of 

 authors ; there are some marks of difi'erence, but they are trivial, and not sufficient to 

 authorize any new specific distinctions." 



Of these last three species, Mayer remarks, " Goodsir's species C. Ixvis and C tuhercidata, were 

 referred by Boeck to G. linearis and G. septentrionalis, the second was referred by Bate to 

 G. acaniliijera ; I refer them both to G. linearis, that is, to C. Johata, Kroyer, var. a and 

 var. y, leaving it on the other hand undecided, whether Goodsir's G. linearis has anything 

 in common with the Linnaean species." In a note Mayer observes that Goodsir rightly 

 distinguished his Caprella luhereiiJafa from Caprella acanthifera, Leach, by the double 

 fringe of sj)ines on the lower edge of the inferior antennaj. The name Caprella lulierculaia 

 was preoccupied by Gueriu, whose species is most probably distinct from Goodsir's.

The giant Amphipod here described is closely allied to one which was among the first prizes of 

 the Challenger dredgings, and which, owing to the comparatively scanty supply of literature 

 available on board, was considered to be of a new genus, receiving the title Thamiwpx 

 pellucida. Guerin says : — - 



"La famille des Hyperines se compose aujourd'hui de 15 genres, tons formes avec des 

 Crustaces de petite taille. En voici un que I'on pent regarder corame un geant dans sa 

 famille, car il est cinque ou six fois plus grand que les plus grandes esp^ces connues. Ce genre
