have the cutting edge not, as in that genus, simple, but minutely denticulate, 

 and the palp of the 1st pair of maxillae is far less developed, the maxillipeds 

 less robi;st; finally the basal joint of the penultimate pair of pereiopoda is 

 narrow linear, as with the preceding pair. The Challenger species of Andania, 

 described by the the Rev. Mr. Stebbing, agree with the present genus in the 

 poor development of the palp of the 1st pair of maxilla?, but seem in other 

 respects to diifer so essentially from the nothern forms, as perhaps more 

 properly to be referred to one or more distinct genera.

 Andania nordlandica, Boeck, Crust, amph. bor. & arctica, p ig. 



Body short and compact, quite smooth, with broadly vaulted back. 

 Cephalon without any distinct rostral projection, lateral corners nearly rect- 

 angular. First segment of mesosome scarcely attaining tlie length of the 2 

 succeeding ones combined. First pair of coxal plates oblong triang\\lar, much 

 deeper than they are broad at the base ; the 2 succeeding pairs i-ather nar- 

 row and obliquely truncated at the tip; 4th pair nearly as broad as they 

 are deep, inferior edge strongly curved in the middle, posterior expansion 

 rather large, and blunted at the tip. Last pair of epimeral plates of meta 

 some scarcely produced at the lateral corners, which are nearly rectangular. 

 Eyes narrowly oblong, tapering above, white, with a reddish tinge in their 

 inferior part. Superior antennae with the 1st joint of the peduncle somewhat 

 longer than the other 2 combined, flagellum scarcely twice as long as the 

 peduncle, 1st joint very large, nearly as long as the other 3 combined, 

 accessory appendage scarcely exceeding half the length of the 1st joint of 

 the flagellum. Inferior antennae about the length of the superior, but much 

 more slender, last joint of the peduncle somewhat shorter than the penulti- 

 mate one, flagelli;m about the length of the peduncle. Gnathopoda of moderate 

 size, propodos fully as long as the 2 preceding joints combined. Penultimate 

 pair of pereiopoda with the basal joint but very slightly dilated in its distal 

 part, meral and propodal joints about equal in length. Last pair of pereiopoda 

 scarcely more than ^/s as long as the preceding pair, basal joint oval in 

 form, and about the length of the remaining part of the leg, deflexed lobe 

 rather large and obtusely pointed at the tip, meral joint much expanded, 

 fully as long as the 2 outer joints combined, and jutting oiit posteriorly to 

 a pointed lobe, reaching nearly to the end of the carpal joint. Last pair of 

 iiropoda with the rami longer than the basal part, terminal joint of the
