AMPIIIl'ODA NOUMALTV. 



inferior an{?le of the carpus is gradiml in different species, from 

 heing only inferiorly, but not anteriorly, produced, to being antero- 

 inferiorly pi-odueed to nearly the h-ngth of the propodos ; so that 

 Dana " doubted the propriety of sustaining the genus of Kriiycr 

 based on this distinction — that is, on having well-formed hands 

 terminating the second pair of gnathopoda." 



Assuming, of which I have little doubt, that this is the same species 

 as that figured and described by Krciyer in his ' Grijnlauds Amfipoder,' 

 I am much inclined to consider it as a sjTionym of H. galha, the only 

 difference between them being scarcely more than a variation, and 

 consisting in the absence of any traces of articulation in the flagella, 

 and in having the carpus of the second pair of gnathopoda a little 

 more produced anteriorly. 



4. Hyperia macrocephala. (Plate XLIX. fig. 2.) 

 Tam-ia macrocephala, Dana, JJ. S. Exphr. Exped. p. 988. pi. G8. f. 2. 



" Cephalon very large, and nearly filled A\-ith the pigment of the eyes. 

 Pereion short and stout : fourth coxa produced below and acute ; 

 fii-st, second, and third truncate. Antennae short (hardly as 

 long as half the height of the cephalon), subequal, subiilate ; ex- 

 tremity multiarticulate. Fii-st pair- of gnathopocla shortest, quite 

 pubescent ; carpus broad, more than twice as long as the meros, 

 and much longer than the propodos ; dactylos minute. Pereiopoda 

 subequal and naked. Three posterior paii-s of pleopoda unequal ; 

 the antepenultimate pair reaching very nearly to the apex of the 

 ultimate ; the penultimate jxiir reaching only to the apex of the 

 bixse of the ultimate. 



" Length 9 lines.

5. Hjrperia agilis. (Plate XLIX. fig. 3.) 

 Hyperia agilis, Dana, JJ. S. Explor. Exped. p. 986. pi. 67. f. 11. 



" Cephalon of moderate size ; pigment of eyes much smaller than 

 usual. Pereion long. All the coxae short, truncate. Antennge 

 rather long (half as long as the pereion), subequal : inferior slightly 

 the longest, three-jointed, not terete ; last joint long and remotely 

 hairy : superior five-jointed ; foiu-th joint stout, long, ciliate below ; 

 the last minute. Gnathopoda subequal; coxae narrow. Three 

 posterior paii-s of pereiopoda of moderate length ; setse short and 

 few.
